Performance Analysis of Bidirectional Electric Vehicles Charging Station with PV Integration

Abstract

There are significant obstacles for operation and dependability of the system with the growing use of electric vehicles (EVs), transportation systems, and distribution generators (renewable resources) for power generation. This paper designs a bidirectional control technique that provides efficient operation during the charging and discharging of EV batteries. The Photovoltaic (PV) array is integrated with the system to charge the EV batteries and reduce the reliance on the grid. But due to the environmental conditions, the fluctuations in PV generation are very high. The interface between these systems is not well understood. The control technique is essential to secure reliable operation and enhance the performance of the system. This technique controls the voltage deviation of the grid at the point of common coupling and reduces the total harmonic distortions (THD) while EVs are charging/discharging with the PV array.
