Abstract: As the prerequisite for participating in the power market or grid scheduling, determining the overall operation characteristic of virtual power plant has been widely studied in recent years. Based on the principle and advantages and disadvantages of the algorithm, the operation characteristic aggregation method of distributed energy resource in virtual power plant is summarized in this paper. First, the difficulties of operation characteristic aggregation of distributed energy resource in virtual power plants are analyzed from the perspectives of economy and technology. Then, as technical virtual plants, the aggregation algorithms of adjustable power domain and adjustable power cost are introduced. Determination methods of bidding electricity price or bidding electricity quantity of commercial virtual power plants as price receiver and price maker are described in detail. Finally, combined with the development requirements of high proportion new energy system in the future, the research direction of operating characteristic aggregation algorithm of virtual power plant is prospected.
