摘　　要：针对可再生能源发电不断并入配电网,配电网出现双向流动的有功潮流,使配电网输电线路的有功潮流越来越不确定的问题,把握配电网关键线路的有功输电规律对于保证输电安全、防止大面积停电事故的发生具有重要意义。对此,在量测环境下,提出了基于双向长短期记忆网络的配电网关键线路单调性规律提取方法。首先,建立了配电网输电网潮流计算模型;在此基础上,给出了配电网关键输电线路的识别方法;基于双向长短时记忆网络方法,建立了配电网关键线路单调性的规律提取方法;最后,以某实际电网为例,表明了所提方法的有效性。In view of the fact that renewable energy power generation is continuously integrated into the distribution network, the active power flow in the distribution network appears two-way flow, which makes the active power flow of the transmission lines in the distribution network more and more uncertain, grasping the active power transmission law of the key lines in the distribution network is of great significance to ensure the transmission safety and prevent the occurrence of blackout accidents. Therefore, in the measurement environment, a method based on bidirectional long short-term memory network is proposed to extract the monotonicity law of key lines in distribution network. Firstly, the power flow calculation model of distribution network is established. Secondly, on this basis, the identification method of key transmission lines in distribution network is given. Thirdly, the monotonicity rule extraction method of key transmission lines in distribution network is established based on bidirectional long short-term memory network method. Finally, a real power grid is taken as an example to show the effectiveness of the proposed method.
