| 摘 要： | 目的 针对电动汽车光伏充电站的有序充电问题，提出一种分时段有序充电策略。 方法 研究了光伏充电站的结构体系及工作原理，构造了电动汽车充电时间、储能电池荷电状态（SOC）范围等约束条件。负荷高峰时段，在满足车辆充电需求的同时，减少向电网的购电量，降低购电费用，并辅助电网“消峰”。负荷低谷时段，在满足车辆充电需求的同时，增加向电网的购电量，辅助电网“填谷”。 结果 通过仿真事例验证了所建模型的有效性，并与即时充电方案进行比较，说明了所建模型在减小充电站的购电费用，降低电网峰谷差方面的优势。 结论 所提电动汽车光伏充电站的充电策略是正确并有效的，可为实际应用提供参考。

| Abstract: | ［Introduction］ Aiming at the problem of orderly charging of electric vehicle photovoltaic charging stations， the paper aims to establish a bucketed order charging strategy. Method The structure and working principle of the electric vehicle photovoltaic charging station were studied， and the charging conditions of the electric vehicle and the state of charge of the energy storage battery were constructed. During the peak load period， while meeting the vehicle charging demand， reduces the power grid purchases and the cost of electricity purchase， assisted the power grid to “eliminate the peak”. During the low load period， while meeting the vehicle charging demand， increased grid purchases and assists the power grid to “fill the valley”. Result The validity of the model is verified by simulation examples， compared with instant charging solutions， shows the advantages of the builted model in reducing the cost of electricity purchase and reducing the peak-to-valley difference of the power grid. Conclusion The charging strategy of the proposed electric vehicle photovoltaic charging station is correct and effective， and can provide reference for practical applications. |
