This allows dimensional checking to detect possible errors in equations. The units for variables make it easier to interpret, input and plot their values. When we infer the unit of a variable we get the same benefits also for variables without a declared unit. We will use unit inference and checking for the combination, even if the check is primarily a dimensional check.\n\nBoth dimensional checking and unit inference are already implemented in several Modelica tools, but not consistently. The original motivation for this paper was to understand the different approaches, and demystify the unit handling with the goal of making it more available.

Considering the power of unit checking mechanisms in several Modelica tools today, one can be surprised that unit conversion in Modelica still needs to be performed using error-prone user-written formulas and functions.

However, experiments have revealed that simulation results of the same Modelica model may vary across different platforms (under identical simulation algorithm configurations). The root cause of such discrepancies lies in modeling uncertainties introduced by improper modeling practices, such as insufficient initial constraints or ambiguous state variables selection. Different Modelica platforms employ unique translation strategies when handling model uncertainties. Therefore, consistent model translation must be ensured to achieve aligned simulation results. Model Disambiguation can be done in two ways: by improvements in language, such as propose relevant annotations; by improvements in vendor tools.

Current state-of-the-art PVT collector Modelica models are largely limited to oversimplified, steady-state representations that fail to capture the dynamic thermal behavior inherent to real PVT systems. A comprehensive Modelica model is developed based on the ISO 9806 standard (test method for the quasi-dynamic thermal performance of solar thermal collectors), coupled with an electrical system model through an internal heat transfer coefficient. The model calibration relies exclusively on manufacturer datasheet parameters, thereby eliminating the need for parameter estimation from measurement data. The model is validated using experimental results from an unglazed PVT collector, demonstrating strong agreement for various (weather) conditions. The findings highlight that, while steady-state models may suffice for conventional solar thermal collectors (STCs), accurate PVT modeling necessitates a dynamic approach, particularly for the thermal aspects. The electrical output of the PVT collector is less sensitive to transient effects. In addition to the model formulation and validation, this work presents a user-friendly automated calibration method based on manufacturer data, and critically addresses the limitations and potential trade-offs of using exclusively datasheet-derived parameters, thereby providing a transparent tool for PVT system simulation, design, and optimization within the open-source IDEAS library.", "description": "", "recording_license": "", "do_not_record": false, "persons": [{"code": "APKPXZ", "name": "Lone Meertens", "avatar": "https://pretalx.com/media/avatars/APKPXZ_4MgKBPa.webp", "biography": "Lone Meertens is a scientific researcher at KU Leuven in the Thermal Systems Simulation (The SySi) Team.

Extending on a recent direct collocation-based method for Neural ODEs, we generalize to PeN-ODEs, incorporate physical constraints, and present a custom, parallelized, open-source implementation.

It is based on declarative specification of the control logic, and allows reuse of existing technologies for open-loop and closed-loop control testing through coupling with an HVAC system or a whole building energy model. It supports control testing using MIL, SIL and HIL, and export of digital twins for operational support. The process and ASHRAE Standard 231P have been designed to accommodate existing Building Automation Systems product lines, while also enabling direct code generation such as by using FMI or eFMI. Control deployment can be digital or manual and conformance to the digital specification can be tested formally and programmatically at each step of the control delivery.", "description": "", "recording_license": "", "do_not_record": false, "persons": [{"code": "BDZGLQ", "name": "Michael Wetter", "avatar": "https://pretalx.com/media/avatars/BDZGLQ_ARqi3HH.webp", "biography": "Michael Wetter is a Senior Scientist at the Lawrence Berkeley National Laboratory. \n\nHis research includes integrating building performance simulation tools into the research process, as well as their use for design and operation.

Although sensitivity analysis for continuously differentiable systems is directly supported by the standard, for systems with state discontinuities, it is only possible to determine correct sensitivities to a limited extent. In this position paper, we investigate how sensitivity analysis for discontinuous Functional Mock-up Units (FMUs), i.e. including state and time events, works in theory and which additional steps are required to obtain correct results in practice. We further investigate that these steps are unnecessarily computationally intensive from a mathematical point of view, but cannot be implemented in a more efficient way under the current restrictions of the standard. We therefore make a concrete proposal for the new layered standard sensitivity analysis (LS-SA) that remedies the current deficits of FMI in the sensitivity analysis of discontinuous systems.

By leveraging FMI 3.0 features such as clocks, clocked variables, and hierarchical terminals, the standard defines two complementary abstraction layers: Physical Signal Abstraction (High-Cut): Representing physical signal values as clocked variables. Network Abstraction (Low-Cut): Emulates hardware-level bus protocols (e.g., CAN, Ethernet) using FMI 3.0\u2019s clocked binary variables. Aligning with the V-model development process, we demonstrate how these layers address distinct challenges in different design phases: High-Cut supports require- ments engineering and functional testing by simplifying signal exchange during Virtual Electronic Control Unit (vECU) integration. Low-Cut enables later phases of the design validation by replicating network timing and protocol specific properties, such as error handling.

Extensive simulations are required to assess the impact of numerous inverter-based resources (IBRs) deployed to the large-scale NYS power grid, aiming to evaluate their dynamic behavior and mitigate any negative interactions with their control schemes. However, the modeling efforts required are huge and the computational burden of large-scale simulations is extensive, and often limited by the capabilities of domain- specific tools. This work addresses these limitations by developing a Functional Mockup Unit (FMU) of Grid- Forming (GFM) Inverters for IBR control and integrating them with an electromechanical phasor-domain power system solver. The proposed FMU facilitates the simulation and parametric studies needed to analyze large- scale IBR usage with significantly improved manual modeling and computational efforts. The paper details the process of developing and FMU model for GFM IBRs, including all relevant control loops implemented in the Modelica language and FMU integrated in OPAL-RT\u2019s ePHASORSIM software.

This results in a critical opportunity to improve waste management systems by advancing circular economy objectives for material recovery whilst avoiding burden shifting. \nWaste management systems are multi-domain, multi-energy and multi-product (\u201cWaste-to-X\u201d): they include logistics, storage units, chemical conversion processes of waste materials into valuable resources such as energy, fuels, chemicals, or recycled materials, and all types of related processing for these commodities. The integration of waste treatment technologies via superstructure optimization has been extensively studied to improve resource valorization, but the drawback of integrated mathematical models is the lack of flexibility for refined process design. The evaluation of site-specific Waste-to-X systems critically requires the inclusion of dynamic models, with the capability to include any type of complexity such as the modeling of heterogeneous flows to track all impurities and compounds across a system, as well as the implementation of control strategies for the operations of the units. The analysis of such systems should handle input data uncertainties and provide transparent performance indicators computation to increase stakeholders\u2019 confidence in the results. \nIn this contribution, we present specific tool requirements to assess waste management systems, and introduce a corresponding design of a simulation and optimization framework. The tool (\u201cplatform\u201d) relies on OpenModelica for waste treatment process modeling and simulation, and on Python interfaces for data management, process and system co-optimization, and post-processing workflows to provide key performance indicators. We show how the platform structure allows to account simultaneously for the three pillars of sustainability (economic, environmental and social) for decision-making in an industrial R&D context. We provide insights on modeling conventions and emphasize their importance when establishing the Life-Cycle Inventory, for instance when defining heterogeneous streams (which can be environmental emissions, exchanged commodities or waste streams). We present how the Modelica-Python interface is built, showing how input data and modeling documentation are handled systematically to increase transparent evaluation of Waste-to-X systems. \nWe illustrate platform features (\u201cworkflows\u201d) such as pinch analysis for process heat integration, Life-Cycle Impact Assessment (LCIA), and cost breakdown analysis, on municipal solid waste treatment systems including sorting technologies, storage tanks, waste incineration, and post-combustion carbon capture.", "description": "", "recording_license": "", "do_not_record": false, "persons": [{"code": "AYJB8A", "name": "Julie Dutoit", "avatar": "https://pretalx.com/media/avatars/AYJB8A_busWneO.webp", "biography": "EPFL: MSc in Energy Sciences & Technology (2022).\nWorking at Kanadevia Inova AG in Zurich (Switzerland) since 2021, now since 2022 simultaneously as PhD student from EPFL (Lausanne, Switzerland) and as a Process Engineer in the R&D Renewable Gas Department.", "public_name": "Julie Dutoit", "guid": "a2705fec-b4e2-52d6-964b-8629f4512c43", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/AYJB8A/"}, {"code": "XBWSCS", "name": "Manuela Goulart", "avatar": null, "biography": "", "public_name": "Manuela Goulart", "guid": "c01cd477-a678-5b44-bf5b-7614647001cf", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/XBWSCS/"}, {"code": "UJNHAR", "name": "Mae McKenna", "avatar": null, "biography": "", "public_name": "Mae McKenna", "guid": "61f08d06-4bfe-5f45-a030-b7d91aa66609", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/UJNHAR/"}, {"code": "XVTZ7G", "name": "Jaroslav Hemrle", "avatar": null, "biography": "", "public_name": "Jaroslav Hemrle", "guid": "0ccb52b5-9ba5-5697-aece-386981dace4a", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/XVTZ7G/"}, {"code": "JVEFTC", "name": "Jana Lukic", "avatar": null, "biography": "", "public_name": "Jana Lukic", "guid": "f0a7aec4-e52b-5421-b53c-7cc35f37bb67", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/JVEFTC/"}], "links": [], "feedback_url": "https://pretalx.com/16thmodelicafmiconference/talk/8ACE8N/feedback/", "origin_url": "https://pretalx.com/16thmodelicafmiconference/talk/8ACE8N/", "attachments": []}, {"guid": "2ce93b4b-c887-5e4a-975e-a10656faf2ed", "code": "DGXCAF", "id": 80576, "logo": null, "date": "2025-09-09T10:45:00+02:00", "start": "10:45", "end": "2025-09-09T11:10:00+02:00", "duration": "00:25", "room": "203", "slug": "16thmodelicafmiconference-80576-on-the-challenges-of-large-scale-simulation-platforms-andour-solution-to-overcome-them", "url": "https://pretalx.com/16thmodelicafmiconference/talk/DGXCAF/", "title": "On the challenges of large-scale simulation platforms andour solution to overcome them", "subtitle": "", "track": "Modelica Applications", "type": "Paper", "language": "en", "abstract": "Operator training simulators are one of the cornerstones of Model-Based Systems Engineering and a key technology to enable cost-efficient, fast, safe and customizable training.

(2) The pressure to increase development speed and efficiency to stay competitive. There are solutions addressing both challenges: Model-based systems engineering (MBSE) addresses consistency and traceability, while virtualization and simulation address development speed and efficiency. In state-of-the-art industrial practice, however, these two solutions are still applied in isolation from one another, leading to inconsistencies, missing traceability and high effort and resource investment (due to redundant or manual modeling work, finding and correcting inconsistencies etc.). To address these industry challenges, the prostep ivip SmartSE project\u2014an established multi-year cross-industry initiative\u2014has been working on integrating MBSE with simulation to enhance traceability, consistency and efficiency in product development processes. We will present our industry experiences and the obtained results from the SmartSE project, where our companies collaborate on solving the real-world challenges that drive the urgent need for a standards-based integration of MBSE and simulation. Related standardization efforts include the \"Simulation Credibility Standard and Recommendation\" [1] from SmartSE, the SysML specification for creating MBSE system architecture models [2], and the SSP Traceability Standard [3]. The unique value of this presentation lies in bringing together industry perspectives from OEMs, suppliers and tool vendors to share their experiences, challenges and targets with the integration of MBSE and simulation. Rather than only presenting theoretical solutions, we will also show working proof-of-concepts created within the SmartSE project. The proposed solutions are based on standards (SysML, XMI, SSP, SSP-Traceability, FMI) and thus applicable across industries, irrespective of the specific tool set used in an organization. Our presentation will reveal how the integration of MBSE and simulation enables consistency and traceability between quantitative (i.e., system architecture model) and qualitative (i.e., simulation models) models, whilst increasing development speed and efficiency due to auto-generation of artifacts. We provide industry insights into why the integration of MBSE and simulation is an essential means for traceability, consistency and development speed, and how it can be put into practice.\n\nReferences [1] White Paper: SmartSE - Guard Rails for \"Simulation Credibility Standards and Recommendation\", prostep ivip Association.

Therefore, the use of modeling & simulation activities as part of product development and release is also increasing. Traceability is for these activities a keystone for quality tracking and reuse for efficiency. This presentation shows how this can be realized by applying the SSP Traceability layered standard (i.e., which information is involved related to the modeling and simulation activity, where does it come from and where shall it be propagated) in conjunction with the MIC Core standard for metadata. At the beginning, the Credible Simulation Process Framework developed as part of the prostep SmartSE project is presented, which enables integration into company processes. We will show this using the example of the challenges of developing a simulation model Due to different reasons, the development of a simulation model typically consists of the design and the implementation in a simulation tool (e.g. Dymola), the model being then immediately used for simulation purposes, skipping essential activities like the requirement specification (e.g. relevant application area, relevant physical effects, \u2026), the documentation for the end-user and/or the model verification respectively the model validation. Often, the user documentation is written afterwards from the model implementation, leading, e.g. to potential transcription issues, inconsistent content respectively versions between implementation and documentation, and high review efforts to ensure the high quality of the developed model. We will then present the solution approach based on the SSP 2.0 and SSP Traceability Layered Standard and show it as a demonstration. Another important point for traceability and reuse is the use of standardized metadata to find and evaluate information. We will present a solution based on the MIC-Core Metadata Standard. We will close with an overview, which of these solution elements are implemented and publicly available.", "description": "", "recording_license": "", "do_not_record": false, "persons": [{"code": "WY37LH", "name": "Dag Br\u00fcck", "avatar": "https://pretalx.com/media/avatars/WY37LH_IHrodad.webp", "biography": "Technology architecture director, working on Dymola development in a broad sense since 1992.

Simulation models designed to represent the behaviour and features of real systems are increasingly available for testing during the early phase of the full development, but in many cases, their testing suffers from the availability of test oracles. Metamorphic testing has become increasingly used in different application domains as an approach to test systems when an explicit test oracle is unavailable. In order to increase its adoption by domain experts, we combine metamorphic testing with Behaviour Driven development for the verification and validation of simulation models. The tool-based approach facilitates automated test generation based on domain-specific custom metamorphic transformations to generate meaningful test inputs for metamorphic input relations. The method also uses features and scenarios extracted from system requirements and domain expertise to define metamorphic output relations. By automating test generation based on system behaviours as features, scenarios, metamorphic transformations, and output candidates for metamorphic relations in a Gherkin-like format, the tool enables practitioners to verify models based on domain-specific constraints and metamorphic relation checks.

Many such systems involve complex variability. Modelica, a leading equation-based language for modeling and simulating physical systems, struggles to manage this complexity.

This work introduces a context-oriented modeling paradigm for Modelica by integrating Petri Net-based context control with FMI-based Variable Structure Systems (VSS). Specifically, we present Context Petri Nets (CoPN) as a formal mechanism for representing and managing contextual dependencies. By combining CoPN with VSS, our approach enables advanced variability management, supporting the modeling and simulation of complex, context-aware CPS.", "description": "Speaker on Duty: Zizhe Wang", "recording_license": "", "do_not_record": false, "persons": [{"code": "8PEPZL", "name": "Christian Gutsche", "avatar": null, "biography": "", "public_name": "Christian Gutsche", "guid": "e1e42e25-7c3e-5879-bfc1-1b8642a0bce9", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/8PEPZL/"}, {"code": "CMJUFS", "name": "Zizhe Wang", "avatar": "https://pretalx.com/media/avatars/CMJUFS_5W7jJ9v.webp", "biography": "Zizhe holds degrees in Mechanical and Automobile Engineering.\nSo basically, if it moves, he knows how it works.\n\nSince 2019, however, he\u2019s been more fascinated by Deep Learning, which eventually lured him into the world of Computer Science. \nNow, he\u2019s pursuing his PhD in Computer Science.\n\nLet\u2019s just hope he manages to finish it successfully in 2025!", "public_name": "Zizhe Wang", "guid": "8d4fc4bd-417c-55f7-a20b-be9f5483757b", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/CMJUFS/"}, {"code": "MS9C3E", "name": "Uwe A\u00dfmann", "avatar": null, "biography": "", "public_name": "Uwe A\u00dfmann", "guid": "17d7e58c-d192-5450-8430-ea289baa00ef", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/MS9C3E/"}], "links": [], "feedback_url": "https://pretalx.com/16thmodelicafmiconference/talk/HRT78M/feedback/", "origin_url": "https://pretalx.com/16thmodelicafmiconference/talk/HRT78M/", "attachments": [{"title": "Presentation", "url": "/media/16thmodelicafmiconference/submissions/HRT78M/resources/_CQM96Za.pdf", "type": "related"}]}, {"guid": "35deb9e7-af5c-5288-88ba-5b5852e7bf2e", "code": "JZQD7Q", "id": 81133, "logo": null, "date": "2025-09-10T14:09:00+02:00", "start": "14:09", "end": "2025-09-10T14:10:00+02:00", "duration": "00:01", "room": "202", "slug": "16thmodelicafmiconference-81133-session-chair", "url": "https://pretalx.com/16thmodelicafmiconference/talk/JZQD7Q/", "title": "Session Chair", "subtitle": "", "track": "New Translation Methods and Tools", "type": "Session Chair", "language": "en", "abstract": "This session is chaired by", "description": "", "recording_license": "", "do_not_record": false, "persons": [{"code": "KPKQ7S", "name": "Dirk Zimmer", "avatar": "https://pretalx.com/media/avatars/KPKQ7S_SzwXq4W.webp", "biography": "Dirk Zimmer Chairman of the Modelica Association and Coordinator for Methods and Tools regarding simulation at the Institute of Robotics and Mechatronics within the German Aerospace Center (DLR).

For over two decades, Carrier has relied on Modelica as a cornerstone technology for model-based product design.

Today, while controls development remains a vital application, Carrier has expanded Modelica\u2019s use across the entire product lifecycle\u2014from conceptual design, through testing and verification, to business sales tools, and into operation with monitoring and diagnostics. Design and operation of highly integrated energy systems such as data centers and district heating systems also calls for new methods and tools. Differentiated applications has driven diversified analysis with Modelica models. Modelica-based steady-state simulation has emerged as a back-bone in product design, sales tools, as well as in field diagnostics.

Simulation models that can capture simultaneous heat and mass transfer phenomena associated with frost/defrost behaviors and their impact on the overall heat pump system performance are of critical importance to improved controls of heat delivery and frost mitigation. This paper presents a novel frost formulation using an enthalpy method to systematically capture all phase-change behaviors including frost formation and melting, retained water refreezing and melting, and water drainage during cyclic frosting and defrosting operations. A Fuzzy modeling approach is proposed to smoothly switch source terms when evaluating the dynamics of frost and water mediums for numerical robustness. The proposed frost/defrost model is incorporated into a flat-tube outdoor heat exchanger model of an automotive heat pump system model to investigate system responses under cyclic operations of frosting and reverse-cycle defrosting.", "description": "", "recording_license": "", "do_not_record": false, "persons": [{"code": "8JRFDD", "name": "Jiacheng Ma", "avatar": null, "biography": "", "public_name": "Jiacheng Ma", "guid": "e2d5d6a9-d496-5471-8bf8-7fa5600480c9", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/8JRFDD/"}, {"code": "BNXZJR", "name": "Matthis Thorade", "avatar": "https://pretalx.com/media/avatars/BNXZJR_vOOswLd.webp", "biography": "Matthis Thorade has been using Modelica for modeling of thermofluid systems since 2008, focusing on fluid properties, heat exchangers, vapor compression cycles and robust numerics.

This paper provides a dynamic analysis of a commonly used VCC model, identifies and analyzes the root cause of this variation, and proposes a number of remedies. The cause lies within the dynamic equations that result from application of the principle of mass conservation. In many common formulations, these equations express the conservation of mass as one or more differential equations that equate the time derivative of mass to zero. The resulting set of n ordinary differential equations (and a number of auxiliary algebraic equations) include the time derivative of a mass constraint function, but not the actual mass constraint function itself. As a result, this modeling formulation has the following properties: (1) equilibrium solutions of the system are neither isolated, nor exponentially stable; (2) a linearization about any equilibrium solution has at least one eigenvalue equal to zero, making an equilibrium solution stable, but not exponentially stable; (3) for a VCC model formulated using two fluid states per control volume, a one-dimensional equilibrium manifold exists containing all of the equilibrium solutions, and is parameterized by the total fluid mass; (4) an (n-1) dimensional, stable, invariant manifold exists transverse to the equilibrium manifold, defined by the mass constraint function, and on which analytic solutions to the model evolve and the total fluid mass remains constant; and (5) numerical solutions may drift off of this manifold, resulting in an observed drift of fluid mass. These properties have consequences for simulation, control design, numerical model reduction, and state estimation. A number of methods to stabilize the mass constraint are proposed and a number of examples that illustrate the behavior, analysis and remedies are provided.", "description": "", "recording_license": "", "do_not_record": false, "persons": [{"code": "C98AT8", "name": "Christopher Laughman", "avatar": null, "biography": "Add your biography.", "public_name": "Christopher Laughman", "guid": "dda5437d-3f83-57ec-b3cf-820c7b144c93", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/C98AT8/"}, {"code": "SKNQZK", "name": "Scott Bortoff", "avatar": "https://pretalx.com/media/avatars/SKNQZK_n9p0ukY.webp", "biography": "Chief Scientist", "public_name": "Scott Bortoff", "guid": "2f8a995f-faa7-5b1a-8788-fccdaf87f8ff", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/SKNQZK/"}, {"code": "XBXVTM", "name": "Vedang Deshpande", "avatar": null, "biography": "", "public_name": "Vedang Deshpande", "guid": "c81ca5a1-2942-5862-ae9f-24febd0f3cd2", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/XBXVTM/"}, {"code": "GSQSNH", "name": "Hongtao Qiao", "avatar": null, "biography": "", "public_name": "Hongtao Qiao", "guid": "e2597ca2-e83c-55cb-b5d2-d56ebad5c9b2", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/GSQSNH/"}], "links": [], "feedback_url": "https://pretalx.com/16thmodelicafmiconference/talk/KBVKH7/feedback/", "origin_url": "https://pretalx.com/16thmodelicafmiconference/talk/KBVKH7/", "attachments": []}, {"guid": "650bdf78-e4c4-56e7-be70-06732f511933", "code": "TG7HHT", "id": 81208, "logo": null, "date": "2025-09-10T10:59:00+02:00", "start": "10:59", "end": "2025-09-10T11:00:00+02:00", "duration": "00:01", "room": "Audi-Max", "slug": "16thmodelicafmiconference-81208-session-chair", "url": "https://pretalx.com/16thmodelicafmiconference/talk/TG7HHT/", "title": "Session Chair", "subtitle": "", "track": "Energy Generation Systems", "type": "Session Chair", "language": "en", "abstract": "This session is chaired by", "description": "", "recording_license": "", "do_not_record": false, "persons": [{"code": "LK7X9J", "name": "Luigi Vanfretti", "avatar": "https://pretalx.com/media/avatars/LK7X9J_PmIHGcN.webp", "biography": "+20 years for R&D+I for electrical power & energy systems, leading the development of the OpenIPSL - a library for power system modeling and simulation using Modelica.\nFull Professor at Rensselaer Polytechnic Institute, Troy, NY, USA.\nOffering consulting services through Vanfretti Consulting LLC, Troy, NY, USA.", "public_name": "Luigi Vanfretti", "guid": "9296726e-8cfa-5c84-8ea6-1155d58b5dc2", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/LK7X9J/"}], "links": [], "feedback_url": "https://pretalx.com/16thmodelicafmiconference/talk/TG7HHT/feedback/", "origin_url": "https://pretalx.com/16thmodelicafmiconference/talk/TG7HHT/", "attachments": []}, {"guid": "2a76dcac-57e2-5d48-941b-959456960104", "code": "Y379AV", "id": 80562, "logo": null, "date": "2025-09-10T11:00:00+02:00", "start": "11:00", "end": "2025-09-10T11:25:00+02:00", "duration": "00:25", "room": "Audi-Max", "slug": "16thmodelicafmiconference-80562-modelling-and-impact-of-hydraulic-short-circuit-operationin-pumped-hydro-energy-storage", "url": "https://pretalx.com/16thmodelicafmiconference/talk/Y379AV/", "title": "Modelling and Impact of Hydraulic Short Circuit Operationin Pumped Hydro Energy Storage", "subtitle": "", "track": "Energy Generation Systems", "type": "Paper", "language": "en", "abstract": "This paper investigates the hydraulic short circuit (HSC) operation of pumped hydro energy storage systems, specifically how it can be modelled and its impact on energy capacity, efficiency and operating range.

In this work, a pumped hydro storage system with 140.5 MW nominal charging power and 10 h nominal charging time is analysed. The storage is simulated via a dynamic, system-level model composed of detailed physical component models to accurately depict the HSC operating behaviour. HSC enables part-load operation from 39 MW to 107 MW but with significantly lower overall system efficiencies. The HSC operating limits are governed by the turbine's minimum flow and maximum power.

When combined with heat storage and advanced control strategies, it can cover a significant share of heat demands. However, designing and optimizing such systems is complex due to their dynamic behavior and the interplay of multiple physical phenomena. To better understand and design these systems, modeling tools are essential. Modelica is particularly well-suited for this purpose. At Newheat, large scale solar thermal field models have been developed in the Modelica language using the Dymola environment. These models represent the thermal and hydraulic behavior of a solar thermal field at two different levels of complexity. Each is designed for different project phases-fast simulations for early-stage feasibility studies and slower but more detailed simulations for the engineering phase. To assess the accuracy of both models, comparisons with measured data on an operational solar plant were performed. Results indicate that both models achieve high thermal accuracy, with errors of less than 4% in annual heat production. On the hydraulic side, the detailed model provides more precise results than the simplified one. The main drawback of this model being slow simulations in case of very complex solar field layouts. Moving forward, these models will support various applications and enable scalable modeling of complex solar thermal systems, adapting to different project phases and requirements.", "description":

This paper presents ufmu, a lightweight framework that enables execution of FMI 2.0-compliant Functional Mock-up Units (FMUs) within the MicroPython environment, targeting platforms such as the ESP32. The proposed approach translates FMU model descriptions into C structures, integrates them into MicroPython firmware, and exposes a minimal Python API for simulation control, enabling model-based computations on-device without cloud dependencies. We evaluate the framework using a standard FMU model, comparing performance across ESP32, Unix, and plain C environments in terms of memory usage, execution time, and firmware size.

To simulate whole systems, multiple tools are usually needed to cover different parts. These parts include the hardware of a system and the environment the system interacts with. The Functional Mock-up Interface (FMI) standard for co-simulation can be used to connect those tools.\n\nThe control part of modern systems is usually a computing unit, such as a System-on-a-Chip (SoC) or Microcontroller Unit (MCU), which executes software from a connected memory and interacts with peripherals. To develop the software without requiring access to the physical hardware, full-system simulators, so-called Virtual Platforms (VPs), are commonly used. The industry standard framework for VP development is SystemC TLM. SystemC provides interfaces and concepts that enable modular design and model exchange. However, SystemC lacks native FMI support which limits the integration into broader co-simulation environments.\n\nThis paper presents a novel framework to control and interact with SystemC-based VPs using the FMI. We present a case study showing how a simulated temperature sensor in a SystemC simulation can obtain temperature values from an external tool via FMI. This approach allows the unmodified target software to run on the VP and receive realistic environmental input data such as temperature, velocity, or acceleration values from other tools. Thereby, extensive software testing and verification is enabled. By having tests ready and the software pre-tested using a VP once the physical hardware is available, certifications like ISO 26262 can be done earlier.", "description": "", "recording_license": "", "do_not_record": false, "persons": [{"code": "8NUNHK", "name": "Nils Bosbach", "avatar": null, "biography": "Nils Bosbach received his B.Sc. and M.Sc. degrees in Electrical Engineering from RWTH Aachen University in 2019 and 2022, respectively.

When using AC, the in-ductance of the cables results in reactive power that contributes to the load of the cables and increases the voltage at busbars. At the same time, offshore power systems are becoming increasingly complex. They are evolving from dedicated collector grids and transmission cables for wind farms through shared use of transmission cables by multiple wind farms to hybrid offshore grids that connect wind farms to multiple countries. This paper discusses operational challenges of off-shore grids and how they are solved with a model-based master controller that solves optimal power flow problems in real-time. The Kriegers Flak Combined Grid Solution serves as example. It transports wind power from the four offshore wind farms (Baltic 1 and 2, Kriegers Flak A and B) with a total capacity of 950 MW to shore. Additionally, it promotes energy trade between Germany and Denmark. At the heart of the connec-tion of these two energy grids through the Baltic Sea there is a Master Controller for Interconnected Operations (MIO). Based on a Modelica model and using the PowerSystems library, it solves several state estimation and optimal power flow problems in real-time.

Fast Fourier Transform (FFT)-based methods are well-suited for respective analysis. While FFT algorithms inherently assume signal periodicity, rotating systems often exhibit true periodic behavior (e.g., shaft rotation frequencies). Using angle-sampled data rather than time-sampled data allows direct analysis of oscillations relative to rotational cycles, which is particularly useful for tracking unbalance or periodic external excitation in rotating assemblies. Modelica provides several built-in resources to address these challenges. First of all, inverse models have the potential to derive an ideal control signal in time domain. For periodic disturbances, this ideal control is likely to be approximated well by a periodic, i.e. Fourier-transformable signal. Modelica is an appropriate model environment to store and retrieve tabled FFT data depending on operating conditions such as rotational speed. In a real-time application, synthesizing control signals from precomputed Fourier tables offers a practical alternative to executing potentially complex inverse models online, reducing computational effort and system complexity.

While various methods and tools for tolerance analysis exist in the mechanical domain, there is currently no standardized or widely established approach for their integration into multi-domain system simulation. This work proposes a structured FMU interface based on the Functional Mock-up Interface (FMI) standard, enabling a modular and reusable representation of tolerance behaviour. The concept is demonstrated in a case study, in which an FMU for static tolerance calculation was implemented and successfully verified against a commercial analysis tool. Furthermore, the use of the FMU with FMUGym illustrates the potential of the FMI ecosystem to flexibly combine tolerance models with other simulation environments and analysis methods. The results demonstrate that FMUs can provide a suitable and tool-independent interface for integrating geometrical tolerance effects into system-level simulations and model-based engineering processes.", "description": "", "recording_license": "", "do_not_record": false, "persons": [{"code": "VRFCTV", "name": "Christoph Steinmann", "avatar": "https://pretalx.com/media/avatars/VRFCTV_mEhs54J.webp", "biography": "- Research assistant at the Institute of Electromechanical and Electronic Design since 2021\n- PhD student \nfield of research: Simulation of geometric tolerances in the product development process", "public_name": "Christoph Steinmann", "guid": "32f5c397-2f3f-5996-8de9-1cac8478f90a", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/VRFCTV/"}, {"code": "B3CNAM", "name": "Konstantin Wrede", "avatar": "https://pretalx.com/media/avatars/B3CNAM_cpJIPxX.webp", "biography": "PhD student at Fraunhofer IIS in Dresden; I work on bringing learning-based control systems from simulation to reality.", "public_name": "Konstantin Wrede", "guid": "fafdbfb6-b3ce-53d9-8b85-ab4fba9fd627", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/B3CNAM/"}, {"code": "98MH8T", "name": "Jens Schirmer", "avatar": null, "biography": "", "public_name": "Jens Schirmer", "guid": "8f99e688-67c6-54d0-8ea3-0c3d74d44302", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/98MH8T/"}, {"code": "FFJLLB", "name": "Jens Lienig", "avatar": null, "biography": "", "public_name": "Jens Lienig", "guid": "3969dd7a-d828-585c-8200-28b0f6bfc3eb", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/FFJLLB/"}], "links": [], "feedback_url": "https://pretalx.com/16thmodelicafmiconference/talk/UUQSKP/feedback/", "origin_url": "https://pretalx.com/16thmodelicafmiconference/talk/UUQSKP/", "attachments": []}, {"guid": "ff42c27e-edc7-5764-8b12-7d4ecb596fc9", "code": "HH3PC9", "id": 81210, "logo": null, "date": "2025-09-10T10:59:00+02:00", "start": "10:59", "end": "2025-09-10T11:00:00+02:00", "duration": "00:01", "room": "Forum", "slug": "16thmodelicafmiconference-81210-session-chair", "url": "https://pretalx.com/16thmodelicafmiconference/talk/HH3PC9/", "title": "Session Chair", "subtitle": "", "track": "Maritime Applications", "type": "Session Chair", "language": "en", "abstract": "This session is chaired by", "description": "", "recording_license": "", "do_not_record": false, "persons": [{"code": "C9VD3M", "name": "Roger Eivind Stenbro", "avatar": null, "biography": "Add your biography.", "public_name": "Roger Eivind Stenbro", "guid": "2b5acd87-0550-548f-9f08-b75abda4f42c", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/C9VD3M/"}], "links": [], "feedback_url": "https://pretalx.com/16thmodelicafmiconference/talk/HH3PC9/feedback/", "origin_url": "https://pretalx.com/16thmodelicafmiconference/talk/HH3PC9/", "attachments": []}, {"guid": "d29028b8-5185-524a-ba41-f5b75540805e", "code": "T8LTL3", "id": 80475, "logo": null, "date": "2025-09-10T11:00:00+02:00", "start": "11:00", "end": "2025-09-10T11:25:00+02:00", "duration": "00:25", "room": "Forum", "slug": "16thmodelicafmiconference-80475-shared-sea-environment-definition-and-realization-formaritime-and-offshore-co-simulations", "url": "https://pretalx.com/16thmodelicafmiconference/talk/T8LTL3/", "title": "Shared sea-environment definition and realization formaritime and offshore co-simulations", "subtitle": "", "track": "Maritime Applications", "type": "Paper", "language": "en", "abstract": "Marine operations are often developed with the use of numeric simulation, in particular lifting operations and transfer of cargo between different units at sea. The effect of the environmental conditions is often the limiting factor and must be included together with models of different components and sub-systems. This paper describes an approach to synchronize spatial and temporal environment information such as universal constants, current, wind, and wave for use in co-simulations of marine operations. Co-simulation models in marine operations will inherently use physical constants, wind and current velocities to calculate forces. Wind and current velocities can have spatial and temporal variations that require the models to synchronize the values. In the event of simulations in waves, the position of the ocean surface, wave particle velocities must be coherent between individual co-simulation models. Further complicating matters is the case of propulsors that produce forces by creating local currents. This paper suggests a structured description of an environment for co-simulation of marine operations.

Optimization is about improving the capabilities and performance of a system; stress testing is about uncovering its weaknesses and faults. Both require a quantitative representation of the system's behavior, and for complex, multi-physical systems, co-simulation can be a very powerful method to create such a representation. However, co-simulation frequently involves the use of black-box subsystem models, which poses challenges to traditional optimization and stress testing methods. Here, we review the state of the art in co-simulation-based optimization and stress testing, focusing especially on \\emph{adaptive stress testing} in the latter case, and discuss open research questions and promising research directions. In particular, we make the case that a co-simulation is not an entirely black box even when some or all of its subsystems are; it may be possible to exploit the visible system structure, coupling variable values, and partial subsystem information.

In this time, we have worked with several challenges inherent to co-simulation, and its application to model-based assurance and secure industry collaboration. For the past three years, we have had a central role in the SEACo (Safer, Easier, and more Accurate Co-simulations) research project, from which we will present some of the results that we find relevant to the FMI community.\n\nThe coupling problem in co-simulations encompasses not only the challenge of correctly connecting the different simulation models in a larger system but also dealing with the coupling errors that are introduced during the data exchange [2] [3]. In recent work, the concept of power bonds, introduced in bond graph modelling of physical systems, has been applied to co-simulations, resulting in several experimental methods for error quantification and control. In particular, the energy-conservation-based co-simulation method (ECCO) [1] is attractive for co-simulation as it relies only on the coupling signals as power bonds and assumes no additional constraints on the models, co-simulation solver, or FMI version in use. The impact of this approach is highest for couplings with large numerical contributions, where the simplistic discretization found in many co-simulation solvers leads to correspondingly large numerical errors. For stiff couplings, where we here refer to stiffness in the numerical sense, this is of particular interest as an error reducing step size control algorithm may be used to identify a suitable step size for integrating the system equations based on minimizing the observed coupling error for each timestep.\n\nAs a part of case-study in the SEACo project, the ECCO algorithm is applied to the connection between a deck crane and hull. This system is known to be poorly suited for co-simulation because of the large inertias inherent to this coupling. We look at the effect of applying ECCO to such a system, starting with a simplified configuration of two connected masses that can be actuated in one degree of freedom, before considering the same problem under multiple degrees of freedom.\n\nIn SEACo, we also consider assuring complex operations based on simulations. This requires building trust in the chosen simulation methods, the system models, as well as the system integration as a co-simulation. The value of assurance in such a context can only be realized with sufficiently efficient and practical methods, which are currently lacking. We will present from the assurance activities performed in the project, centered on a case study involving a marine lifting operation between two floating structures. We will also connect this work to our recommended practice for the assurance of simulation models, and connected methodology for model qualification, verification, and validation.\n\nReferences [1] Sadjina, S., Kyllingstad, L.

This presentation also introduces the model exchange and co-simulation environment built on cloud server and show example use cases of simulation-based decision making using SmartSE and JAMBE standards, as well as FMI and SSP standards.", "description": "", "recording_license": "", "do_not_record": false, "persons": [{"code": "N779ZX", "name": "Dai Araki", "avatar": "https://pretalx.com/media/avatars/N779ZX_MXfhP9G.webp", "biography": "Chief Specialist, ICT Solutions Division, Toshiba Digital Solutions Corporation\nParticipating in collaborative MBD study groups of\n- prostep SmartSE project group\n- JAMBE (Japan Automotive Model-Based Engineering center)\n- JSAE (Society of Automotive Engineers of Japan) FMI Utilization and Expansion Woking Group", "public_name": "Dai Araki", "guid": "a1cf4ebf-13cb-573c-986a-86a85a972368", "url": "https://pretalx.com/16thmodelicafmiconference/speaker/N779ZX/"}], "links": [], "feedback_url": "https://pretalx.com/16thmodelicafmiconference/talk/QN3HGM/feedback/", "origin_url": "https://pretalx.com/16thmodelicafmiconference/talk/QN3HGM/", "attachments": [{"title": "presentation slides", "url": "/media/16thmodelicafmiconference/submissions/QN3HGM/resources/_8zRgQXF.pdf", "type": "related"}]}, {"guid": "2a987451-9b4b-5493-b3ad-7dcc8ab60d8e", "code": "QBWPWE", "id": 80585, "logo": null, "date": "2025-09-10T15:25:00+02:00", "start": "15:25", "end": "2025-09-10T15:50:00+02:00", "duration": "00:25", "room": "203", "slug": "16thmodelicafmiconference-80585-neural-network-based-reduced-order-model-of-a-large-scale-co-heat-pump-for-real-time-simulation-and-digital-twin-applications", "url": "https://pretalx.com/16thmodelicafmiconference/talk/QBWPWE/", "title": "Neural Network-Based Reduced-Order Model of a Large-Scale\nCO\u2082 Heat Pump for Real-Time Simulation and Digital Twin\nApplications", "subtitle": "", "track": "Model-Based Workflows and SSP", "type": "Paper", "language": "en", "abstract": "This study presents a reduced-order model (ROM) of a large-scale transcritical CO2 heat pump designed by MAN Energy Solutions, currently operating in Esbjerg and under construction in Aalborg, Denmark. The original high-fidelity model, implemented in Modelon Impact and presented at Modelon Innovate, captures the complex thermodynamic and control dynamics of the heat pump but comes with high computational cost, making it impractical for real-time applications. To address this issue, we trained a neural network ROM using simulation data from the Modelica-based model, enabling significant reduction in simulation time without compromising accuracy. We demonstrate how the ROM is integrated back into the Modelica framework to facilitate fast simulations, paving the way for real-time control scenarios and digital twin implementations. Performance evaluations show that the ROM retains key dynamic behavior and delivers simulation speed-ups by more than two orders of magnitude. The model captures start-up and shut-down scenarios, assessing system reliability and transient behavior, and evaluates the heat pump\u2019s flexibility for grid balancing, responding to variable load demands and grid needs. This approach not only accelerates system-level studies but also supports online applications such as fault detection, predictive control, and system optimization. Our work highlights the potential of combining physics-based modeling with data-based machine learning techniques to bridge the gap between simulation fidelity and computational efficiency, crucial for the development of next-generation digital twins in the energy domain.", "description": null, "recording_license": "", "do_not_record": false, "persons": [{"code": "LAA7BL", "name": "Kamran
