Modeling and Simulation of Vehicle-to-Grid (V2G) Systems for Frequency Regulation in Microgrids

This paper presents the modeling and simulation of a vehicle-to-grid (V2G) system used to regulate the frequency in a microgrid (MG) with distributed energy resources (DERs) including a distributed diesel generator (DG), renewable energy sources (RES) like photovoltaic (PV) arrays and wind turbines (WTs), and the residential and industrial loads of the electrical grid. To see the impact of the V2G system on the grid frequency, the proposed MG system is simulated using MATLAB/Simulink software in different operating conditions. Analysis results show the power profile (generation and consumption) and the impact of the V2G system on peak regulation. It has been shown that the proposed V2G system can use the available power to regulate the frequency in the MG when different events affect the grid frequency.
