Abstract

This paper proposes an electric vehicle-energy storage system (EV-ESS) charge/discharge controller based on the deviation between load power and generated power. An interlinking converter is designed which acts as a gateway between AC and DC subgrids of the grid-Tied hybrid AC/DC microgrid system. It has the ability to control both active and reactive power based on individual control mechanisms. To control the reactive power in the system a reactive power controller is proposed and designed within the interlinking converter controller. The reactive power controller operates based on the manipulation of point of common coupling (PCC) reactive power and RMS voltage with their associated references. A generalized grid-Tied hybrid AC/DC mi-crogrid is designed with a PV module and a doubly fed induction generator (DFIG) wind turbine mimicking the real life microgrid model in Griffith University, Nathan campus. The simulation is carried out in MATLAB/SIMULINK environment to prove the effectiveness of both controllers. Simulation results show that both reactive power controller and EV-ESS charge/discharge controller perform efficiently under variable loading and variable irradiation conditions which facilitate smooth vehicle to grid (V2G)/vehicle to microgrid (V2M) operation.
