Modeling and Simulation of Hybrid Renewable Microgrid System

Abstract

This paper deals with the modeling and simulation of hybrid photovoltaic/ wind/ battery system used for isolated sites. In fact, for the wind energy system, a permanent magnet synchronous generator (PMSG) is used. The PMSG model is given in the d-q reference frame. The wind energy system control is determined by using proportional integral (PI) controllers for the currents and the speed. For the photovoltaic system, a PV panel is associated to a boost converter. In order to obtain a maximum of power, the Maximum Power Point Tracking (MPPT) technique is used. Battery is used as energy storage. The proposed hybrid microgrid system performance under different scenarios has been checked carrying out Matlab/Simulink simulations using real weather data.
