Control of Grid-Interfaced Solar Photovoltaic System Assisting Electric Vehicle Charging Dynamics

This work aims to showcase a control scheme for a solar photovoltaic (PV) panel interfaced to the grid supporting a three-phase electric vehicle charging system. It uses a multifarious harmonic elimination (MHE) technique for the operation of the control infrastructure. Peak power is extracted from the PV array and is delivered towards the grid side, where it fulfills the demand of the EV charging dynamics. The MHE based control is employed to exquisitely harvest the fundamental component out of the nonlinear current waveforms. Moreover, the dynamic variations experienced by an EV charging station are satisfactorily fulfilled. The overall system's power quality is maintained throughout the operation. Moreover, the multifarious aspect of the control corresponds to the extraction of third, fifth, seventh and ninth order harmonics and eliminating them from the input signal. The perennial power after the demand of EV charging is transferred to the utility. The performance is tested on developed hardware experimental model. The results unveil the prodigious potency of the presented control scheme.
