摘要

针对电力系统大停电恢复的网架重构过程中可能出现的线路潮流越限问题，文中提出一种网络调整策略。从尚未恢复的网络中寻找能够分担该线路输电功率的所有可行的输电路径组成备选路径集；定义了备选路径的综合评价指标，从后续恢复影响、消除越限效果、系统运行状态的影响和恢复操作复杂度等角度对各备选路径进行评价和排序，排序后的备选路径集作为消除线路潮流越限的网络调整策略。IEEE 39节点系统算例验证了该网络调整策略对消除线路潮流越限的有效性。

Abstract

During the process of network reconfiguration after blackouts

overloading of the restored transmission lines may occur due to pickup of a major load. An optimization control method is proposed by amending the network structure. For the overloaded lines

all the feasible paths that can mitigate the occurred overloading are found out from the unrestored network to constitute a set of optional paths. The optional paths are evaluated and ranked by the effect of subsequent recovery

over-load elimination

operating status

as well as the complexity of the recovery operation. The sorted path set can be the network adjustment strategy for reducing the line overloading. The proposed network adjustment strategy is validated by the simulation results on the IEEE 39-bus power system. This work is supported by National Natural Science Foundation of China (No. 51277076) and Fundamental Research Funds for the Central Universities (No. 2014XS75).
