电动汽车和能量云在家庭微网中的协同调度研究
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 distributed 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 and discharge, efficiently and reasonably exert the ES characteristic of EV, and optimize the energy management of the residential micro-grid (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. Moreover, the energy transaction service in the EC system also promotes the energy interactions and commutations between different users. Taking the depreciation cost of EV and ES into account, the optimization model is established with the target of minimizing the electricity cost of users. 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, and the electricity cost is further reduced.
