Research on typical power customers load model of urban distribution network

In modem electric power systems,a reasonable accurate representation of load is necessary for power system stability and dynamic analysis. Load modeling is one of the most important cause effecting the precision and credibility of the simulation result. For a long time, load modeling studies have been behind the development of the electric power industry. The basic theoretical knowledge of electrical load modeling is introduced and load characteristics of a variety of typical power consumer are also described in the thesis, realistic load modeling methods are selected, improved Comprehensive statistical method combined with the actual modeling ideas is used to construct load model, based on the typical consumer load data, the industrial load static model and the industrial load static model of actual power network are obtained. A useful exploration are carried out for improved comprehensive statistical method to come to practical; what is the most important is that solid foundation is built for establishing integrated actual load model of a urban distribution network in northeast area, new method of industrial load forecast for the region is provided, and the credibility of industrial load simulation of the heavy industrial area is improved.
