Abstract

The paper presents a novel FACTS device developed by the First Author to improve the power quality, reduce total harmonic distortion, decrease AC and DC inrush currents, and provide device voltage stabilization. The novel FACTS device is a AC-DC coupling neutral point filter compensation (NP-FC) which is connected between AC and DC sides of the converter and increases the level of power. A DC-DC buck-boost chopper is also utilized in DC side of the converter to control battery charging and decrease the ripples of the DC side voltage and current. A multi-regulator multi-loop error driven Modified-PID controller is used to control on-off pulsing sequence for NP-FC FACTS device and DC-DC buck-boost chopper. The proposed scheme is validated for V2H battery charging scheme.
