摘　　要：研究大停电后系统恢复后期的负荷全面恢复问题,提出了网架重构结束后负荷恢复策略的优化方法。通过将负荷全面恢复过程划分为几个次序进行的恢复阶段,以每阶段的可投入负荷量最大为目标函数,考虑各节点待恢复负荷的类型差异和停电损失的不同,将负荷恢复优化问题转化成一个0-1背包问题,并采用回溯算法进行求解。提出的负荷恢复策略制定方法同时兼顾了重要负荷的快速恢复及减小系统停电损失两方面的要求。以IEEE30节点系统为算例,验证了提出的恢复方法的有效性,并比较了不同网络重构方案下负荷恢复时间和停电损失的差异性。The full load recovery in the late restoration process of a blackout power system is investigated to build an optimization method for determining the load restoration plans after the network reconfiguration. By dividing the full load recovery process into several sequential restoration stages, the maximized amount of the load restoration in each stage is taken as the objective function, with consideration of the diversity of load types and outage cost at each load bus, the optimization of the load restoration is treated as a 0 - 1 knapsack problem, and the backtracking algorithm is used to solve it. The proposed approach to determine load restoration plans can make a balance between the quick re- covery of the important loads and minimization of the outage cost. The IEEE-30 test system is employed to verify the ef- fectiveness of the proposed method and to assess the difference of load restoration for the different reconfigured networks.
