In an attempt to solve the joint clearing problem of integrated energy system and external grid under the environment of spot market and distribution side deregulation, a two-stage clearing method including day-ahead and real-time stages is proposed considering the mutual balance of interests between multi entities. In the day-ahead clearing stage, multiple rounds of iterative bidding are implemented considering the interest-driven of all entities, and incorporating factors into the day-ahead bidding process, such as mutual insurance, reserve and peak shifting. In the real-time clearing stage, a triple energy supply system from producers, superior power grid and spinning reserve providers is formed by coordinating internal and external reserve, energy supply refinement and interest distribution. Moreover, the clearing decision models for producers, operators, and load aggregators are built. Finally, the effective effects of demand response, mutual insurance contract and spinning reserve market on peak shifting and internal and external reserve are analyzed by case simulation, which shows that the method can realize the supply and demand balance and interest balance between each entity.
