FPGA Based Power Quality Improvement of Grid Connected EV Battery System

Abstract

This article presents a bidirectional converter that allows for both charging and discharging of the EV battery while enhancing grid power quality and we are also using an FPGA-based algorithm in regulating the converter enables instantaneous current generation, which maintains the current at a level below 5 THD, resulting in improved power quality. The approach also effectively manages battery usage by minimizing the use of the EV battery during times of low power quality. Implementing the Instantaneous current generation approach using an FPGA-based algorithm in hardware and simulation can provide an effective way to enhance the grid-connected EV battery system, reduce pollution, and preserve resources in the environment. This approach can also improve the efficiency of the EV charging system, making it more appealing to potential users and accelerating the transition to sustainable transportation. It regulates the bidirectional buck-boost converter during charging and discharging, improving power quality and managing battery usage. The program is designed to charge the battery during high power quality times and minimize battery usage when not needed. Simulation results show a decrease in THD of current. Overall, the approach can enhance the EV battery system and improve power quality.
