CoSiF

Interface Algorithms for Distributed Power System Co-Simulation

CoSif: Co-Simulation Interface Algorithms

CoSif is a collection of co-simulation Interface Algorithms (IA) for (geographically) distributed real-time simulation. It has been developed by the Institute for Automation of Complex Power Systems at RWTH Aachen University with the goal to simplify the execution of distributed co-simulations by using using re-usable library blocks within the simulations models.

We aim to provide a set of tested and interoperable implementations of IA targeted at the following platforms:

  • OPAL-RT eMEGASIM (MATLAB Simulink)
  • RTDS (RSCAD)
  • VILLASnode / DPsim

At the moment we aim to provide interface algorithms for the following domains:

  • HVDC-VSC
  • Vrms / Freq / Phase
  • PQ
  • Dynamic Phasor ITM
