ABSTRACT

The load modeling of the power system of a refining and chemical enterprise is an important basic research, and the establishment of a load model is an important part of the analysis of the stability of the enterprise's internal power grid. Based on the data measured on site, the error function is established to optimize, and the unknown parameters of the polynomial model of the static load and the power function model are identified. The evaluation index of the fitted curve proves that the static load model established by the steady-state test method is feasible and effective.
