Currently, a large number of integrated energy systems operate independently, which is not conducive to the efficient utilization of clean energy. To fully utilize the energy resources of multiple integrated energy systems, realize the local energy consumption and efficient utilization, and further improve the flexibility on the demand side, this paper constructs an optimal scheduling framework for integrated energy systems considering multi-energy sharing and integrated demand response. A cooperative operation model of multiple integrated energy systems is established to minimize overall cost based on Nash bargaining theory. The energy-sharing problem is solved distributively via the alternating direction multiplier method and the stakeholders' privacy and security is protected well. The validity of the proposed model is verified by arithmetic analysis. Compared with the situation of independent operation and no comprehensive demand response, the operation scheduling strategy proposed in this article has better results. Implementing multi energy sharing and comprehensive demand response can save 21.45% of costs. The overall cost of the whole system has been reduced from the initial 18033.26RMB to 14164.39RMB. In addition, In the context of fluctuating renewable energy scenarios, the energy sharing strategy proposed in this article can still effectively reduce energy costs. Therefore, the energy scheduling strategy proposed in this article can promote the utilization of clean energy and has high practical value.
