Normalized Gaussian Kernel LMS controlled Grid interactive PV based EV Charging Station

A grid connected photovoltaic (PV) based electric vehicle (EV) charging station is proposed that provides uninterrupted power supply to EV and non-linear domestic load. Here, PV is responsible for power transfer to the EV and household load. The proposed Normalized Gaussian Kernel Least Mean Square (NGKLMS) control technique mitigates several power quality (PQ) issues arising due to non-linear load, unbalanced load or change in solar irradiance (G). This technique lowers the harmonic content of the grid parameters based on IEEE 519 standard and maintains unity power factor (UPF). The superiority in performance of the proposed control is validated by comparing with conventional techniques like Least Mean Fourth (LMF) and Least Mean Square (LMS) in MATLAB/SIMULINK.
