摘要(Abstract):
针对配电网故障恢复持续时间较长、故障恢复未考虑光伏和负荷功率随时间变化的问题,基于时变性对含光储系统的孤岛划分和配电网故障恢复进行研究。将故障时段内配电网恢复重要负荷总电量最大为上层目标函数,光储系统恢复孤岛内的重要负荷总电量最大为下层目标函数,建立了配电网故障恢复二层规划模型,上下层模型之间的关联实现了配电网故障恢复与孤岛划分整体寻优。分别采用蚁群算法和遗传算法对上下层模型进行求解。仿真结果表明:光伏出力和负荷时变性对配电网故障恢复具有重要影响,配电网进行故障恢复应该结合故障发生后的实际光伏出力和负荷需求进行合理操作;将主网和光储系统进行协调配合能够最大限度恢复失电区域的供电。
