摘要
电力系统发生大停电事故后,含高比例分布式电源的主动配电网可以通过分区实现快速并行恢复。提出了一种主动配电网黑启动分区优化策略。以最小化用户停电损失为目标,建立了主动配电网黑启动分区的混合整数线性规划模型,通过分布式电源、线路、母线和负荷的恢复约束将各个分区内部的恢复操作顺序集成到分区模型中。利用线性规划求解器ILOGCPLEX对所提出的优化模型进行求解,从而得到配电网黑启动分区恢复方案。以改进的IEEE 69节点配电系统为例验证了所提模型与策略的有效性。
When power system blackout occurs,the active distribution network with high penetration of distributed generations can realize fast parallel restoration through zone partitioning.An optimization strategy for black-start partitioning of active distribution network is proposed.With the minimum customer outage cost as objective,a mixed integer linear programming model is established for black-start partitioning of active distribution network,and the restoration operation sequences inside each partition are integrated into the partition model through the restoration constraints of distributed generations,lines,buses and loads.The linear programming solver ILOG CPLEX is adopted to solve the model,and then the partition restoration scheme of distribution network is obtained.The effectiveness of the proposed model and strategy is verified by the modified IEEE 69-bus distribution system.
