A Dynamic Dispatching Strategy for Smart Grid Based on Composite Game Model Considering Preferential Policies

Abstract

Renewable energy resources and electric vehicles give pressure on the smart grid. Once a large number of electric vehicles do batch charging at peak time, the dynamic resource allocation ability of the smart grid appears to be very important. This article proposes one composite game model to describe the interaction process during the charging. The smart grid area covers numbers of charging stations which satisfy spatial non-equilibrium distribution. Each vehicle has enough remaining energy to reach each charging station in the considering field. This paper considers preferential policies to the cost-sensitive drivers. From the view of energy management, preferential policies from charging stations will fluctuate the energy demand. To do dynamic dispatching strategy in power supply, the model describe two type of interactions, one is between stations and vehicles, the other is between vehicles. The model help strategy managers understand more about energy demand which hopefully can assist them do reasonable dynamic dispatching strategy.
