摘　　要：针对区域负荷中含有电源但仍然以电力负荷为主的广义电力负荷,在分析电源对广义电力负荷建模影响的基础上,给出了广义电力负荷的3种模型结构。提出了广义电力负荷模型的参数确定策略,指出等值发电机参数可以采用理论等值方法确定,而负荷模型参数可以采用辨识方法确定。最后给出了仿真结果。The load area including not only loads but also power supplies is defined as generalized loads. Based on the analysis of the impacts of power plants on load modeling, three load models of the generalized loads are gfven in this paper. The methodology for estimating parameters of generalized loads is proposed, it is pointed out that the parameters of equivalent generators can be worked out through aggregation method, and those of equivalent loads can be estimated through measurement based method： A eb.se study is given at the end of the paper.
