Modeling and Simulation of Microgrid Dynamic Operation Modes Using MATLAB Simulink Software

Abstract

Microgrids are one of the effective solutions for utilizing renewable energy sources and distributed generations in distribution networks. This paper proposes a model to study operation modes of a microgrid consisting of a battery energy storage system (BESS), a solar power system, a diesel generator, a main grid and consumers. The microgrid components and control systems are modelled in the MATLAB Simulink software. Based on this model, different operating scenarios including the islanded mode and the black start mode are carried out to analyse and evaluate the dynamic response of the microgrid. The voltage, current, power, and frequency of the various locations on the system are simulated in the scenarios and they indicate that with the support of the BESS control, the microgrid is maintained at a stable operation condition in both studied modes.
