Abstract :
This paper describes the power quality control center (PQCC) for the microgrid systems composed of the photovoltaic power, wind power, fuel cell power, gas engine generator and various power quality loads. PQCC is consisted of a series voltage compensator and a parallel battery energy storage system (BESS). The series voltage compensator is composed of high performance DVR (Dynamic Voltage Restorer) with the neural network controlled voltage disturbance detector and the real-time output voltage regulator. DVR supplies the high quality power to the premium quality load by compensating the voltage disturbance such as voltage sag.
