An open-source Simulink-based program for simulating power systems integrated with renewable energy sources

This paper presents an open-source Simulink-based program developed for simulating power systems integrated with renewable energy sources (RESs). The generic model of a photovoltaic, wind turbine, and battery energy storage is used for the RES. The program can be used for educational and research studies. It comes with several important subjects in power systems including power system modeling and integration, linearization, modal analysis, participation factor analysis, controller selection using residue analysis, and frequency response analysis. IEEE 68-bus dynamic test system is used to verify the performance of the program. The results show the efficiency and speed of the program to simulate a large-scale modern power system.
