摘　　要：电力系统的电力电子化成为新型电力系统的重要特征之一,负荷设备电力电子化也成为发展趋势,电解铝、电动汽车等整流类负荷比重越来越高。随着分布式电源大量接入配电网,大电网负荷特征更加复杂,含有分布式电源的特殊负荷模型亟待研究。本文首先对电力系统负荷建模的两种主要方法——统计综合法和总体测辨法进行了阐述;然后,重点对电解铝、电动汽车、含分布式电源的特殊负荷建模的研究现状进行了分析;最后,对新型电力负荷特性和建模方法进行了展望。The power electronization of the power system has become one of the important features of the new power system,and the power electronization of load equipment has also become a development trend.The proportion of rectifier loads such as electrolytic aluminum and electric vehicles is getting higher and higher.With a large number of distributed generators connected to the distribution network,the load characteristics of the power grids have become more complex,and special load models containing distributed generators are needed to be studied.This article first describes the two main methods of power system load modeling:component-based method and measurement-based method;then,it focuses on the current research status of load modeling of the electrolytic aluminum,electric vehicles,and special load modeling with distributed power sources.Finally,the characteristics of the new power load and its modeling methods are prospected.
