Measurement-based load modeling-model structure

Referenced to the results of component-based load modeling approach, the paper presents an improved composite load model structure that can be applied into measurement-based load modeling area. The improved composite load model can keep its parameters concentrated when the load changes. Besides that, comparing with the typical dynamic load model, the improved composite load model can describe the reactive power of the real loads more accurately. Finally, a great lot of data measured from site were dealt with and the effectiveness of both measurement-base load modeling and load model structure was proved.
