【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]:Aiming at the emergency of power grid under the current state and the anticipated fault, the automatic search algorithm of dynamic partition scheme for multi-area and multi-type emergency is proposed. For dispatchers to formulate control measures and operational ways to provide reasonable auxiliary decision-making advice. Firstly, the dynamic zoning technology is introduced to dynamically adjust the power network zoning structure by means of line switching. Then, aiming at the states of emergency, such as overload and voltage overrun, the automatic searching algorithms of dynamic partition for single state of emergency and multiple states of emergency are given respectively. Finally, the quantitative evaluation index of dynamic zoning scheme considering safety, economy and reliability is put forward. This index can be used to determine the optimal dynamic zoning scheme. The simulation results show that there are many emergency situations in the actual power network. The proposed method can give correct decision-making suggestions and effectively eliminate the emergency of power grid.
