Analysis and comparison of two kinds of composite load model
The accuracy of simulation affects directly the safety and economy of power system. With the development of power grid and wide application of PSS, the effect of load model on the accuracy of digital simulation becomes more and more important. In this paper two kinds of load model are analyzed, one is TVA load model based on measurement, the other is SLM model considering distribution network and shunt reactive compensation. Based on data measured from site, resounding tests are made to compare the accuracy of the two models. The simulation of Jilin grid in China indicates that if the parameter set of SLM model is identified, the accuracy of SLM model is equivalent to that of TVA model. The conclusion is that the effects of the two load models on the simulation are independent of the model structure, only dependent on model parameters.
