【摘要】 配电网中光伏和电动汽车充电站的接入会影响配电网稳定运行，但其各自的灵活调度特性也为配电网增强了一定灵活特性，故提出一种考虑光伏利用效率与电动汽车充电设施数量限制的配电网分布式资源协调控制策略（distributed resource coordination control strategy, DRCCS）。该方法在光伏侧考虑配网中光伏控制能力，协调配网各光伏逆变器的V-Q下垂控制斜率，实现光伏出力优化控制。在电动汽车充电侧考虑实际充电站内充电设施的数量限制，实现电动汽车有序充电，在保证充电需求的前提下调用充电灵活性实现对配网的辅助支撑。综合构建考虑光伏利用效率与电动汽车充电设施数量限制的协调控制模型，实现维持配网电压稳定，提升光伏逆变器有功输出，并保证电动汽车充电需求的目标。所构建的混合整数非线性问题采用广义Benders分解算法（generalized Benders decomposition, GBD）进行求解，并通过仿真验证了该方法的有效性。更多还原

【Abstract】 The integration of photovoltaic(PV) and electric vehicle(EV) charging stations into the distribution network affects the stable operation of the distribution network, but the respective flexible scheduling characteristics of PV and EV charging stations enhance the flexibility of the distribution network. Therefore, a distributed resource coordination control strategy(DRCCS) for the distribution network is proposed, which considers the efficiency of PV utilization and the limitation of the number of EV charging facilities. On the PV side, the V-Q droop control slope of each PV inverter in the distribution network is coordinated, and optimal output control of PV is achieved by considering the PV control capability in the distribution network. On the EV charging side, the number of charging facilities in actual charging stations is considered to achieve orderly charging of EVs. The flexibility of charging is utilized to provide auxiliary support for the distribution network while ensuring charging needs. The coordination control model considering the efficiency of PV utilization and the limitation of the number of EV charging facilities is comprehensively constructed, so as to ensure stable distribution network voltage, improve the active output of PV inverters, and satisfy the charging demand of EVs. The mixed integer nonlinear problem constructed in this paper is solved by the generalized Benders decomposition(GBD) algorithm, and its effectiveness is verified through simulation.更多还原
