Energy Management Strategy for Photovoltaic-Energy Storage Mobile Charging Station

This paper proposes the integration of photovoltaic-energy storage charging stations with mobile charging services (MCD)to form a photovoltaic-energy storage mobile charging station (PV-ES-MCS). The PV-ES-MCS establishes a charging service framework that simultaneously achieves low-carbon environmental benefits and operational flexibility. Furthermore, an energy management strategy is developed that considers both operational economics and mobile charging scheduling requirements. Through detailed analysis of the PV-ES-MCS system architecture, comprehensive modeling of operational costs and revenues is conducted. By incorporating the energy replenishment demands of mobile charging scheduling and operational cost reduction, an energy management objective function with corresponding constraints is formulated and solved using the Grey Wolf Optimizer algorithm. Case study results demonstrate that the proposed strategy enables coordinated multi-element regulation within the PV-ES-MCS station, reducing operational costs by 6.7% while effectively ensuring the energy replenishment efficiency of mobile charging scheduling with 100% MCD battery swap success.
