By using BSS to manage the charging of EVs, microgrids can mitigate grid congestion issues caused by multiple EVs charging simultaneously. BSS can distribute the charging load intelligently, considering grid constraints and available capacity, to prevent overloading and ensure a reliable power supply to both EVs and other critical loads .
The integration of EV charging with RESs and storage systems is a concept that aims to maximize the benefits of clean energy generation while efficiently managing EV charging and grid interactions.
Thus, connecting BSS with EV charging stations in microgrids offers several benefits in terms of operational efficiency, cost reduction, and environmental impact . BSS can help balance the load by absorbing excess energy during periods of low demand and supplying it to EV charging stations during peak demand.
BSS can store excess energy during low-cost periods and discharge it during high-cost periods. By leveraging time-of-use pricing, microgrids can optimize the charging of EVs to align with cheaper electricity rates, resulting in cost savings.
The charging and discharging patterns of EVs are influenced by several key factors, including the number of EVs connected for charging, the type and speed of the charging stations, the state of charge (SoC), battery capacity, duration of charging, and the start time of charging .
By assigning equal weights of 0.5 to each objective, the optimization sought to find solutions that provide an equitable compromise between the objectives of reducing operational expenditures and lowering the environmental footprint of the microgrid system. The three objective functions are subject to the following constraints:
