Abstract

Electric Vehicle Charging Stations (EVCS) with Solar Photovoltaic (PV) integration require efficient power management to ensure grid stability and battery longevity. This study proposes a hybrid energy storage system (HESS) utilizing Superconducting Magnetic Energy Storage (SMES) and Battery Energy Storage System (BESS) to mitigate transient power fluctuations and optimize energy distribution. The proposed current control strategy is validated through MATLAB/Simulink simulations under Variable Load Constant Generation (VLCG) and Constant Load Variable Generation (CLVG) scenarios. The results indicate that SMES integration reduces the peak battery current by 52.63 % and 32.72 % following the connections of EV-1 and EV-2, respectively, thereby enhancing battery lifespan. Additionally, real-time validation using the dSPACE DS1202 platform confirms that the proposed system effectively stabilizes grid voltage and optimizes power flow under varying load and power generation conditions. The findings demonstrate the efficacy of the HESS in reducing peak transient currents and improving the overall reliability of solar PV-supported EVCS.

基于混合储能系统的太阳能光伏电动汽车充电站电池寿命提升的先进能量管理策略

与太阳能光伏（PV）集成的电动汽车充电站（EVCS）需要有效的电源管理，以确保电网稳定性和电池寿命。本研究提出一种利用超导磁储能（SMES）和电池储能系统（BESS）的混合储能系统（HESS），以缓解暂态功率波动并优化能量分配。通过MATLAB/Simulink仿真验证了所提出的电流控制策略在变负荷恒变发电（VLCG）和恒负荷恒变发电（CLVG）两种场景下的有效性。结果表明，在EV-1和EV-2连接后，SMES集成使电池峰值电流分别降低了52.63%和32.72%，从而延长了电池寿命。此外，使用dSPACE DS1202平台进行的实时验证证实，该系统在不同负载和发电条件下有效地稳定了电网电压并优化了潮流。研究结果证明了HESS在降低峰值瞬态电流和提高太阳能光伏支持的EVCS的整体可靠性方面的有效性。
