Impact of EV Interfacing on Peak-Shelving & Frequency Regulation in a Microgrid

Abstract

A "vehicle-to-grid system" enables electric vehicles to be charged by the grid and to discharge electricity back into it when required. This paper presents the performance of a microgrid under the condition of interfacing the electric vehicle with a typical microgrid, which consists of solar, wind, and diesel power generation along with residential and industrial loads. In this research, the V2G effect on chopping the peak of load and on the regulation of frequency is observed. Diverse practical situations are considered to find the effect under a wide range of scenarios. The complete Phasor model is modelled and simulated in MATLAB/Simulink. Simulation results show that for a wide range of inputs V2G effectively regulated the grid frequency and reduced the peak of power demand.
