Coalition Game Based Optimized Operation Method for Integrated Energy Systems

As the reformation and development of energy industry, future energy system will become more diversified. The integration and complementary of various energy will be trends of future integrated energy system. A coalition game based optimum operating method for integrated energy system is proposed. Firstly, based on energy hub model, a bi-level optimization model is established considering integrated demand response and distributed energy generation such as wind power and solar power. The upper level is to maximize the revenue of the energy suppliers, and the lower level is to minimize the energy purchasing cost of the customers. Then, a non-transferable utility coalition game model for energy hubs is developed, implementing the cooperation of energy hubs. The proposed model is solved by a distributed coalition formation algorithm. Example is given to verify the feasibility and efficiency of proposed model and methods. It is verified that the proposed method can decrease energy waste, reduce energy purchasing cost and promote the economy and flexibility of the multiple energy systems.
