Fig. A1. Local optimal solution and global optimal solution. In order to make the integer variables (the number of charging piles) optimizable in an effective way, the charging demand of EVs in the PV-ES-CS is calculated under different numbers of charging piles at first, then the demand is called in the optimization program directly.
The coupled photovoltaic-energy storage-charging station (PV-ES-CS) is an important approach of promoting the transition from fossil energy consumption to low-carbon energy use. However, the integrated charging station is underdeveloped. One of the key reasons for this is that there lacks the evaluation of its economic and environmental benefits.
Furthermore, the utilization of energy storage with EMS for real-time charging and discharging scheduling allows for the effective control of the wholesale store’s electricity consumption within a lower contracted capacity, thus further reducing the charging station’s electricity costs.
The capacity optimization model of the integrated photovoltaic- energy storage-charging station was built. The case study bases on the data of 21 charging stations in Beijing. The construction of the integrated charging station shows the maximum economic and environment benefit in hospital and minimum in residential.
Solar-and-energy storage-integrated charging stations typically encompass several essential components: solar panels, energy storage systems, inverters, and electric vehicle supply equipment (EVSE). Moreover, the energy management system (EMS) is integrated within the converters, serving to regulate the power output.
The economic and environmental benefits of the integrated charging station also markedly differ on different scales: with scale expansion, the rate of return on investment and the carbon dioxide emissions reduction first increase and then decrease.
