Model Structures and Parameter Estimation of Generalized Loads

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 given 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 case study is given at the end of the paper.
