Abstract
本发明提供一种含微电网的配电网供电恢复方法及系统，该方法包括：获取配电网区域网络结构及负荷信息；分析配电网孤岛划分要求；基于孤岛划分要求建立孤岛划分模型，搭建配电网孤岛划分目标函数，建立约束条件；结合专家经验和熵权法确定模型中目标函数各权重指标，得到合理精准的孤岛划分模型；通过智能算法对孤岛划分模型解，实现配电网各区域网络的孤岛划分，充分发挥微电网支撑配电网供电能力。本发明可在配电网发生严重故障情况下，基于优先保障重要负荷、便于故障恢复后重新接入原则，通过配电网孤岛划分模型，将配电网区域主动解列为若干个独立的孤岛，以此保障配电网负荷的不间断供电，从而提升配电网故障恢复的快速性和可靠性。
