The V2 G network is made up of a large number of electric vehicles,recharging stations and power grid.In the V2 G network,electric vehicles can either be charged from the grid or fed to the grid.If a huge number of electric vehicles access to the grid without control,it will bring a "peak plus peak" pressure to the power grid.Therefore,the power grid needs to acquire the information about the charging willingness and position of the electric vehicle in time,and remotely monitor the operation status of the power station.According to the load condition of the power grid,the electric vehicles will be macro-charging control.How to guarantee the reliability and timeliness of communication between electric vehicle,recharging stations and power grid in V2 G environment in an efficient way has become an important problem in V2 G technology.In this paper,the V2 G network system composed of electric vehicle,public charging station,parking lot charging station,aggregator,and energy supply and demand manager is studied.The information flow type and the process of charging and feeding,as well as the current V2 G network communication technology,designed to achieve the booking charge,global feed,local feed and price management function of the V2 G charge and discharge scheduling management communication protocol.According to the demand of power flow and information flow in various functional components of V2 G network,this paper uses two kinds of V2 G element model to implement three modules in the V2 G network simulation system.These modules are the application layer management control module,the resource-scheduling module and the mobile management module.Through the simulation test,the transmission success rate and network delay of V2 G network simulation system are tested and evaluated.At present,there is no mature application of V2 G charging,dispatching management communication standard,so this paper designs a charging,and dispatching management communication protocol of V2 G network has a certain theoretical and application reference value.
