Energy Management Strategy for Grid-Connected Charging Station Systems with Predefined Grid Energy Consumption Levels

The increasing adoption of electric vehicles and the accompanying expansion of charging infrastructure pose significant challenges to the existing electrical network. Therefore, it is essential to address these challenges by implementing support mechanisms designed to mitigate future problems. This paper presents an energy management strategy for a grid-connected charging station system with predefined maximum grid consumption levels and incorporated local energy sources. Integrating local energy sources and an energy management strategy reduced grid energy consumption from 62.34 MWh to 20.35 MWh. The presented energy management strategy demonstrates the capability to adhere to the predefined grid energy consumption levels, thereby minimizing the strain imposed on the electrical network during the charging process.
