摘要

针对当前状态和预想故障情况下的电网紧急状态，提出多区域多类型紧急状态时的动态分区方案自动搜索算法，为调度员制定调控措施和运行方式提供合理化辅助决策建议。首先，引入了以线路投切为手段动态调整电网分区结构的动态分区技术；然后，针对设备过载、电压越限等紧急状态，分别给出了单一紧急状态和多种紧急状态时的动态分区自动搜索算法；最后，提出了综合考虑安全性、经济性和可靠性的动态分区方案量化评价指标，该指标可用于确定最优动态分区方案。算例以实际电网中同时出现多种紧急状态为例，分析了动态分区方案制定过程。仿真结果表明，所提方法能够给出正确的辅助决策建议，有效消除电网的紧急状态。

Abstract

According to the emergency situations of current state and anticipated faults

an automatic searching algorithm of dynamic partitioning scheme for multi-region and multi-type emergency situations is proposed

which can provide reasonable auxiliary decision-making for control measures and operation mode. Firstly

the dynamic partitioning technology(DPT)is introduced

which takes transmission line switching to dynamically adjust the grid partition structure. Considering emergency situations such as equipment overload and voltage violation

the automatic searching algorithms of DPTs for a single emergency and multi-emergencies are given. Finally

concerning safety

economy and reliability

a quantitative evaluation index of dynamic partitioning scheme is proposed to determine the optimal scheme. With an example of multi-emergencies occurring in an actual power grid at the same time

the execution process of dynamic partitioning scheme is analyzed. Simulation results show that proper auxiliary decision-making strategies can be obtained by the proposed method to relieve the emergency.
