Abstract: As an important class of structure in future power system with the integration of high shares of renewable energy resources, virtual power plant（VPP） integrated diversified distributed energy resources（DER） to promote renewable energy generation. In order to enhance the capability of VPP for wind power accommodation, "Generation-LoadStorage" multi-type reserve capacity system of VPP was established based on the composition characteristics of VPP, and a risk-based reserve decision method was proposed. Considering conditional value-at-risk（CVa R） as a tool to assess the risk loss produced by the uncertainty of wind, the coordinated optimal model of generation and reserve of diversified DERs was built based on a cost-benefit analysis. The rationality and effectiveness of the presented method and model were validated by numerical results.
