Abstract: In response to the implementation of the“carbon emission peak and carbon neutrality”energy policy and the development requirements of the new power system,the research on new electric power load models and modeling methods can provide critical support for power system planning,stability analysis,dispatching control,and marketization operation.Firstly,the research history of load models and parameter identification methods at home and abroad is reviewed,and the research progress of new load element models,including controllable loads,distributed generation systems,distributed energy storage systems,and electric vehicles,as well as oscillating dynamic load models and harmonic load element models under the new distribution network framework is summarized.Secondly,the classic load modeling methods are summarized,their advantages and disadvantages are analyzed,and the measurement-based load modelling method is emphatically discussed.Finally,from the points of new load characteristic modeling,dynamic load model considering the impact of new technology,load aggregation model and online load modeling method,the prospects have been put forward,providing a practical technology roadmap for the technical development of future power load model.
