基于IGWO-BP的配电网接线方式综合评价

配电网接线方式的优劣,影响着电力系统运行的稳定性与安全性。对配电网接线方式进行评价研究,为配电网的合理规划提供科学的指导意见,是配电网规划建设的重要内容。为了提高配电网接线方式评价的准确性,基于经济性,可靠性,安全性,建立了配电网综合评价指标体系。提出了一种改进的灰狼算法(IGWO)优化BP神经网络(IGWO-BP)的算法,将IGWO选择的最优位置作为BP算法的权值和阈值。建立基于IGWO-BP的配电网接线方式评价方法,将配电网接线方式评价指标体系作为IGWO-BP的输入,将评分值作为IGWO-BP的输出,建立配电网接线方式评价模型。算例仿真验证了所提方法的有效性和可靠性。

Comprehensive evaluation of distribution network connection mode based on IGWO-BP

The advantages and disadvantages of the connection mode of distribution network affect the stability and security of power system operation.The evaluation and research on the connection mode of distribution network can provide scientific guidance for the rational planning of distribution network,which is an important content of distribution network planning and construction.In order to improve the accuracy of the evaluation of distribution network connection mode,a comprehensive evaluation index system of distribution network is established based on economy,reliability and safety.An improved grey wolf algorithm(IGWO)is proposed to optimize BP(IGWO-BP)neural network.The evaluation method of distribution network connection mode based on IGWO-BP is established.The evaluation index system of distribution network connection mode is taken as the input of IGWO-BP and the scoring value as the output of IGWO-BP,and the evaluation model of distribution network connection mode is established.Simulation results show the effectiveness and reliability of the proposed method.
