Abstract

With the development of load modeling technology, the accuracy of load model is increasingly required. In addition, as the end user of power, the accuracy of load model has a great impact on the simulation of power system. In the load modeling of large power grids, 220KV or 110KV substations are generally used as load nodes, and enterprise load modeling is rarely carried out. In view of the shortcomings of the current comprehensive load model in the enterprise load grid structure, due to the large proportion of the enterprise motor load, this paper uses the comprehensive statistical method based on statistical data to divide the motors with different load characteristics into multiple motor groups, and then aggregate the motor clusters into equivalent motors. Then, according to the characteristics of motors and the influence of distribution network impedance, the motors in the enterprise are aggregated into two or more motor groups to realize the integrated load modeling of the enterprise load grid.
