Implementation of Coordinated Control and Power Flow Management Strategy for a Solar Powered EV Charging System

Abstract

A solar-integrated electric vehicle (EV) charging system is presented in this project along with a new approach to power flow management and coordinated control, CC-PFMS. Built within the CC-PFMS is the capacity to automatically balance power consumption across different modes of operation and different energy sources. In addition, regardless of the dynamics of the charger system, it will make it easier to direct power flow from the grid to the battery or the other way around. One major benefit of the suggested technique is that it can detect and stabilize operation under a variety of scenarios, including changes in solar irradiance, vehicle availability, and battery charging/discharging states. With ANN enhancing PV MPPT, the battery's load is reduced by 20%, leading to minimum current usage. The innovative method is put to the test using a 1.5 kW charger system that incorporates a photovoltaic (PV) source that is linked to the utility grid. Comprehensive MATLAB simulations validate the CCPFMS performance throughout many operating modes, including grid to vehicle (G2V), vehicle to grid (V2G), PV to vehicle (PV2V), PV to grid (PV2G), G2V+PV2V, V2G+ PV2G, and PV2V+PV2G.
