Hierarchically partitioned coordinated operation of distributed integrated energy system based on a master-slave game

Abstract

-- With the rapid development of the energy internet, integrated energy system (IES) has become a topic of interest in the field of energy research. In light of energy interconnection system containing multiple communities, this paper proposes a hierarchically partitioned coordinated operation method for distributed integrated energy system (DIES) based on a master-slave game. First, based on the concept of "distributed autonomy and centralized coordination", a hierarchically partitioned structure of urban integrated energy system is given, and a variety of energy equipment are modeled and analysed. Next, in considering the energy and interest interactions among different communities, the urban manager and community operators are taken as the game leader and game followers, respectively, to establish a hierarchically partitioned master-slave game optimization model of DIES based on game theory, and a mixed integer linear programming method is applied to solve the model. Finally, a typical case of urban integrated energy system is taken as an example to verify the optimization model. Simulation results show that the proposed method can effectively promote the balance of energy supply and demand, and reconcile the benefits of leader and followers, while further realizing the economic, flexible and efficient operation of DIES.
