Abstract
In the recent era, there has been a surge in the use of Electric Vehicles (EVs) as a result of rising fossil fuel prices and rising Carbon Dioxide (CO2) emissions. Thus, an EV charging station that utilizes Renewable Energy Sources (RES) offers a significant advantage as well as a certain level of control. The fact that EV charging stations run on the current utility power grid systems places more strain on it and raises distribution-side load demands. As a consequence, this paper discusses the application of Photovoltaic (PV) fed energy efficient DC-DC high gain interleaved SEPIC converter with pigeon inspired optimization for ultra-fast charging systems. The proposed high-gain converter offers constant input current, capacity to handle the highest amount of current, increased efficacy and higher step-up voltage gain. Furthermore, the pigeon optimization algorithm is employed to regulate the high gain interleaved SEPIC converter that has an ability of rapid convergence speed and strong robustness with better optimization characteristics. To store extra electricity from solar panels, the battery storage system is implemented. The stored energy can be utilized when solar panels aren’t producing enough electricity, and the overall proposed system is executed in MATLAB/Simulink. Finally, the comparative analysis is carried out to show the importance of developed work; as a result, the proposed high gain Interleaved SEPIC converter attains a high efficiency of 94.9% and low THD of 2.33% respectively.
