中文摘要: 随着可再生分布式电源(DG)在配电网中的渗透率不断提升,如何充分利用DG与主网联合对非故障失电区域恢复供电引起了人们的重视。对孤岛与主网联合恢复供电的配合性以及风光荷的波动性问题进行了研究。首先,综合考虑了风光荷的波动性问题,建立了广度与深度优先搜索相结合的动态孤岛划分策略;然后,为实现孤岛与主网联合恢复供电的最优性,建立了具有配合性的两阶段规划模型,一阶段以主网通过重构恢复重要负荷最大化为目标,二阶段以主网和DG孤岛联合恢复重要负荷最大化为目标,两者目标之间存在一定的关联性,能够实现联合恢复供电的整体寻优;最后,利用改进IEEE 33节点系统算例验证了所提方法的可行性与有效性。
Abstract:With the increasing penetration of renewable distributed generation in distribution networks,how to fully utilize the joint restoration of non-faulted blackout areas by DG and the main network has attracted much attention.This paper focuses on the coordination between islanded microgrids and the main network for joint power restoration,as well as the fluctuation issues of wind and solar loads.Firstly,a dynamic islanding partitioning strategy combining breadth-first search and depth-first search is proposed,considering the fluctuation issues of wind and solar loads.Secondly,in order to realize the optimality of the joint restoration of power supply between the island and the main network,a two-stage programming model with coordination is established.The first stage aims at maximizing the important load of the main network through reconstruction,and the second stage aims at maximizing the important load of the main network and the DG island.Due to the certain correlation between the two objectives,the overall optimization of the joint restoration of power supply can be realized.Finally,the feasibility and effectiveness of the proposed method are verified using an improved IEEE 33-node example.
