Research on synergetic scheduling of electric vehicles and energy cloud in residential microgrids
With the significant progress in technologies of electric vehicle (EV), its characteristic of energy storage (ES) has attracted extensive attention. However, the primary function of EV is still a sort of transportation. When considered as distributed energy storage (DES), the EV does not possess the stability and persistence which is inherent in traditional energy storage units. In order to reduce the adverse effects of disorder charge/discharge, efficiently and reasonably exert the EV’s characteristic of ES, and to optimize the energy management of the residential microgrid (RMG) system, a novel electricity scheduling architecture based on synergetic scheduling of EVs and shared ES under the operation of the energy cloud (EC) operator is proposed in this paper. The EC operator is not only the provider of shared ES devices, but also the agent which aggregates all the EVs involved in electricity scheduling. Besides, the energy transaction service in the EC system also promotes the energy interactions and commutations between different users. Taking the depreciation cost of EV into account, the optimization model is established with the target of minimizing the user’s cost on electricity. Case study of the RMG validates the justifiability and economic feasibility of the strategy proposed in this paper. And the energy transaction service is proved to be beneficial to all the participants.
