DESCRIPTION:From power grids to hydrogen pipelines and diffusion processes\
 , dynamic flow networks are ubiquitous in science and engineering. In this
  talk\, we present NetworkDynamics.jl\, a Julia package for modelling such
  systems\, along with PowerDynamics.jl\, a domain-specific library for pow
 er grid simulations built on top of it.\nBoth packages have been around fo
 r many years. However\, over the last 1-2 years we have essentially rewrit
 ten both from the ground up\, fully embracing ModelingToolkit.jl as the pr
 imary way to define component models and deepening our integration with th
 e broader SciML ecosystem.\nNetworkDynamics.jl enables users to model inho
 mogeneous network systems in terms of components: dynamical systems on nod
 es (e.g. generators or pumps) and on edges (e.g. power lines or pipelines)
 . Component models can be defined using ModelingToolkit.jl and are then pl
 aced on a graph. The interconnection between components is handled by our 
 performance-oriented backend. This clear separation between dynamic models
  and network topology enables efficient scaling for large networks. Rather
  than symbolically analyzing the entire system—which may contain hundred
 s of thousands of equations—we compile each component type once and reus
 e it across all instances.\nThe resulting system is simply a right-hand si
 de function for a differential equation\, making it fully compatible with 
 the SciML ecosystem: OrdinaryDiffEq.jl for time integration\, SymbolicInde
 xingInterface.jl for accessing network states and observables\, and SciMLS
 ensitivity.jl for parameter optimisation.\nWe will present the underlying 
 mathematical model\, demonstrate applications in hydrogen networks and pow
 er grids\, and show how Makie.jl\, Bonito.jl\, and GraphMakie.jl can be us
 ed to build interactive dashboards for exploring simulation results.
