Abstract 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. Keywords Renewable energy sources (RESs) · Power system modeling · Power system integration · Simulink
1 Introduction With the growing penetration level of renewable energy sources (RESs) such as wind turbines and solar photovoltaic (PV) plants, there is an increasing need by researchers to develop programs that include modeling of new power-electronic-based sources. Since mid-2014, major commercial and professional software platforms have added the generic model of RESs to their libraries based on the plant model developed primarily by Western Electricity Coordinating Council (WECC) and extended later by Electric Power Research Institute (EPRI) for stability studies [3–7]. Some of these platforms are GE PSLF, PSS\E, PowerWorld Simulator, etc. These programs are professional, well coded, computationally efficient, fast, and accurate. However, commercial software has four The author would like to share the program publicly (open source). The link to the files can be obtained from [1]. A short video was created while running the program and is available in [2]. * Ismael Abdulrahman [email protected] 1

main drawbacks [8–10]: (1) its components are “closed source”; the user is not allowed to edit the code sources except for some special cases; (2) it is expensive; (3) it provides less educational due to the closed-source nature of its components; and (4) it requires training courses. On the other hand, MATLAB\Simulink is a high-level language platform, less expensive, and available at almost all universities, and students and researchers are familiar with it. Although Simulink has added block elements in its library for the wind turbine, solar plant, and battery systems, however, none of these components are based on the generic model developed recently by EPRI and WECC.
