摘　　要：建立符合实际的电力系统动态负荷模型的重要性已越发突出,但因设备众多、类型繁杂、结构和参数时变性强、分散性强等,负荷建模有着实质的困难。文中综述了负荷建模现状,对负荷建模难点问题进行评述,继而基于在线综合负荷主导参数测辨方法提出区域综合负荷整体等值和参数测辨方案,概括其中的关键技术及初步解决方案,包括区域负荷划分方案、处理负荷群间的关联、大容量发电机接入负荷群和关键负荷群的特殊处理等。Nowadays,it is of great importance to build proper load models with practical parameters.However,due to the large numbers of equipment involved,increasing complexity in element structures,time varying characteristics and dispersibilities of load structures and parameters,it is essentially difficult to achieve this.This paper gives an overview on the research and development of power system modeling,and presents a descriptive review of several essential challenges in load modeling.A load area integral equivalence and parameter identification scheme is proposed.This scheme is based on an online dominant parameter identification method.Finally,key techniques for implementing the scheme are summarized with preliminary solutions,including load area partitioning,disposal of electrically related load groups,disposal of larger generation access points and key load groups.
