Power Quality Enhancement in PV and Battery Storage Based Microgrid Using Hybrid Active Filter

In this work a photovoltaic (PV) and battery storage system (BSS) based microgrid (MG) integrated with shunt hybrid active filter (SHAF) is proposed for power quality (PQ) enhancement in three phase system. The proposed system is developed to reduce harmonics and manage the reactive power in the power system. For tracking the maximum power in the PV array, a novel self-tuned perturbs and observe (SPO) algorithm is employed. The SHAF employs a maximize M Kalman filter (MMKF) for reference current estimation and hysteresis current control (HCC) for switching signal generation. The proposed system is compared with the traditional Kalman Filter using MATLAB/Simulink tool.
