GMCC based Adaptive Filter for SPV-RES to Improve Power Quality in Distribution Grid

The distribution grid (DG) suffers from poor power quality due to the nonlinear/unbalanced loads. Hence, this paper presents the generalized maximum correntropy criteria (GMCC) adaptive filter-based control algorithm for the solar PV renewable energy system (SPV-RES) to improve power quality in the DG. The SPV-RES improves the power quality in the DG by forcing the DG currents balanced and distortion-free. During the daytime, the SPV-RES feeds the extracted energy of the PV array at the point of interconnection (POI) and improves the power quality. During the nighttime, it operates as a shunt compensator and improves the power quality only. Hence, the utilization factor of the presented system is higher as compared to the conventional system as the presented system operates all the time. Moreover, the presented SPV-RES feeds reactive power to compensate for the load reactive power demand. Hence, the DG power factor remains unity and the line losses are reduced. To validate the performance of the presented system, a simulation model is developed and its performance is investigated in the presence of the nonlinear/unbalanced load.
