Abstract: In the regional integrated energy system, different stakeholders usually have various optimization objectives and supply energy demands. In particular, the appearance of multiple novel power transaction subjects makes it more sophisticated for controlling strategies and decision-making mechanisms related to power transaction. As a result of that, it is an inevitable trend to bring in price-oriented gaming mechanism to balance the gap among multiple benefits. Considering multiple stakeholders sequence and fluctuating changes in the energy trading process, a leader-follower electricity market mechanism model based on Stackelberg game theory and electricity market basic rules is brought out in this paper, in which user aggregators integrate demand resources and negotiate with industrial park operators. Then negotiating strategies and game rules between industrial park operators and user aggregators are analyzed by qualitative methods. Besides, two stage-optimization algorithms are used to solve this model. By the comparison and analysis of optimization results, it is verified that the proposed mechanism could guarantee the economic interests of the three parties as well as improve the weak positions of aggregators and enterprise users during gaming mechanism. Therefore, it is of great significance for electricity market operation, reducing the peaking cost of large users and relieving the pressure on the power grid.
