摘要
文章主要构建了基于电压暂降识别的配电网运行可靠性评估模型.通过电压暂降检测系统获取实际运行数据,采用基于序贯蒙特卡洛的概率仿真方法进行可靠性指标计算,并结合配电网拓扑和设备参数构建了精细化网络模型.在此基础上,提出多准则优化的配电网运行决策支持系统.仿真实验表明,该模型能够精确评估配电网的运行可靠性,为配电网的运行规划提供可靠的决策依据.
Abstract
This paper mainly constructs a reliability evaluation model of distribution network operation based on voltage sag identification.The actual operation data is obtained by the voltage sag detection system,and the reliability index is calculated by the probability simulation method based on sequential Monte Carlo,and a refined network model is constructed by combining the distribution network topology and equipment parameters.On this basis,a multi-criteria optimization decision support system for distribution network operation is proposed.The simulation results show that the model can accurately evaluate the operation reliability of distribution network and provide reliable decision-making basis for the operation planning of distribution network.
