Optimum Design of On-Grid PV-BESS for Fast Electric Vehicle Charging Station in Brazil

Smart charging associating the synergy benefits of Photovoltaics (PV) systems and Battery Energy Storage Systems (BESS) can be used to minimize the negative impacts of Electric Vehicles (EVs) on the power distribution system. However, Electric Vehicle Charging Stations (EVCS) based on PV-BESS are more complex, and several topics must be analyzed, such as size and management. Concerning the sizing perspective, the present paper aims to provide an option to Brazilian charging infrastructure thought of an on-grid PV-BESS for fast EVCS. The proposed system comprises a modular solution that increases the PV power installed according to the previous load demand between 2020 and 2030. The power grid impact will be presented by comparing the required PV power installed to the consumed power from the grid by the charging station. The Homer Grid software is used to model, simulate, and optimize the EVCS.
