Since recent decades, the depletion of fossil fuels and the alarming increase of greenhouse gases in the environment have led to the deterioration of environment on a large scale. Therefore, environmental protection is increasingly opening the door in the advancement of renewable energy-based systems. The system described in the study includes an electric vehicle that is connected to the distribution grid, together with PV and wind energy in combination with a battery in one case and without a battery in another. To determine the impact on LPSP, RF, and NR, comparative evaluations of two instances are performed in one case and without a battery in the other by using Firefly and PSO. Utilizing such a system is proposed to enhance the reliability of renewable energy sources, bolster system dependability, and concurrently lead to reduced expenses associated with electric vehicle (EV) ownership.
