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:

• VILLASnode / DPsim

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

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

The latest version of the CoSiF libraries can be found at RWTH’s GitLab server:
