Nonlinear processes are extremely frequent in the process of the industry, and it is always better to build a stabilizing controller to optimize the rate of output. One of the recent emerging technology which makes the system nonlinear is electric vehicle charging stations. This research work aims to optimize the PI controller with a voltage-oriented controller-based Vienna rectifier for electric vehicle charging stations (EVCS). With the trial and error method for EV charging stations, the PI controller parameters K-p and K-i values, the error values such as integral square error (ISE) and integral absolute error (IAE), system parameters such as rise time settling time, and peak overshoot values are extremely high in the Vienna rectifier based VOC system. Due to the increased system parameters, the stability of the system has been reduced, which approaches a reduction in the system efficiency. The system parameters must be mitigated to provide stable operation to overcome the aforementioned issues with EV charging stations. In this research work, the PSO optimization-based PI controller for EV charging stations has been proposed. The proposed PSO-PI controller optimizes the control parameters and reduces the error values to make the system more stable. The proposed system is simulated and optimized using MATLAB software. The proposed PSO-PI controller-based EV charging station improves the system stability 12% more than the existing VOC controller with Vienna rectifier for EV charging stations. © 2021 IEEE.
