Abstract A novel electric load modeling method is presented from the view of information fusion.First,the framework of electric load modeling is given with the evidence reasoning algorithm as a basic theoretical tool,which not only develops the traditional classification and modeling method in a new way,but also satisfies the needs of simulations in various environments.Secondly,the electric load model is built in detail based on the evidence reasoning algorithm.With the model,information of electric load from various sources,levels,and times can be fully utilized and the complex load characteristics are described accurately.The specific links,e.g.the choice of evidences and the assignment of basic reliability,are also analyzed.The simulation results demonstrate its effectiveness in the online simulation and predictive simulation,respectively.
