Control of Single-Phase Bidirectional PEV/EV Charger Based on FCS-MPC Method for V2G Reactive Power Operation

Abstract

This paper presents the design of a finite control set model predictive controller (FCS-MPC) for single-phase bidirectional PEV/EV charger for vehicle to grid (V2G) reactive power operation. In addition to charging the battery, the proposed method can provide reactive power to the utility grid. The desired topology of the charger consists of two stages; a multilevel H-Bridge AC–DC converter and an isolated DBRCS bidirectional DC–DC converter. The AC-DC converter is controlled by the FCS-MPC strategy, which, in addition to simplicity, improves the dynamic performance of the battery charger. Furthermore, the single-phase shift (SPS) control is used for the DC-DC converter. This paper investigates single-phase schemes of the proposed charger and control system. The proposed control of battery charger is theoretically analyzed and the simulation results are presented using the MATLAB/SIMULINK software.
