A Hybrid Multi-Loop Controlled FACTS-based Smart V2G Battery Chargers

Behnam Khaki, Adel M. Sharaf


The paper presents a flexible hybrid FACTS based AC-DC interface scheme with Flexible AC Transmission System Neutral Point Switched Filter Compensator (NPSFC) stabilization scheme developed by the Second Author to improve power quality and energy utilization in future Smart Grid-V2G Electric Vehicle (EV) Fast Battery Charging Stations. The FACTS-based filter compensation scheme proposed in this paper is equipped with a novel multi-loop dynamic error driven time de-scaled controller to enhance power factor, stabilize AC and DC side Common Bus voltages, ensure efficient energy utilization, and halt inrush current especially under fast battery charging modes. The FACTS-based hybrid filter compensator is a pulse width modulated/switched capacitor compensation scheme which uses IGBT/MOSFET switches. In addition, a revised controller is designed to improve the utilization of the DC bus voltage in combination with a Green Plug Filter Compensator (GPFC) device. GPFC device is controlled by a novel dual-loop controller which handles the voltage and current of the DC side of the rectifier. Output signals of the controllers are the inputs for weighted-modified-PID which its output feeds the sinusoidal Pulse Width Modulation (PWM) block. In other words, the control signals of the controllers are used for regulating the PWM (on-off) pulsing sequences. The unified scheme is validated Using MATLAB/SIMULINK toolbox
