Study on Synthesis Load Modeling for North China Power Grid

This paper mainly surveyed and classified all the 220kV substations of North China power grid, selected some typical substations for load characteristics investigation, and built the SLM (synthesis load modeling) of each class load using investigation on Component based method. At last, the SLM was popularized to the North China power grid. In addition, the impact of new load model to the security level of North China power grid was studied.
