Electric vehicles(EVs)become one of the most important active loads in the distribution network. With the opening-up of electricity market

the charge optimization management of EV has become one of the important research parts. As an effective solution to the management of distributed energy resources(DERs)

the traditional definition of virtual power plant(VPP)focuses on the increase of the renewable energy consumption into power grid by the integration and utilization of low-capacity DERs in the power generation side. However

based on reformation of electricity selling mechanism in China

this paper proposes that the VPP is used as an electricity retailer to participate in the coordinated optimization model of the management of EV charging. In the energy market trading model

distributed power of VPP and aggregator agents of EV participate in the electric power declaration and transaction of electricity market. In the model of Stackelberg game

VPP is expected to lead the EV orderly charging into the grid of EV through making the reasonable electricity retail price. In addition

the centralized coordinated dispatch of VPP optimizes the output of DERs. The illustrative example verifies the effectiveness and economic improvement of VPP in the centralized optimal management for the energy complementary of DERs and EV.
