Research on the cooperation stability and operation strategies of heterogeneous energy alliances based on multi-scale cost equilibrium

With the goal of high proportion new energy generation, this study investigates the dynamic evolution mechanism of the cooperation stability (hereinafter referred to as "stability") of heterogeneous energy, as well as the relationship between the energy supply demand power imbalance mechanism and the cost equilibrium allocation among the alliance participants. Based on the Largest Consistent Set (LCS) stability analysis method of each agent's cost deviation, a multi-scale scenario stability operation strategy model of the alliance is constructed. The impact mechanism of time of use (TOU) pricing on the cost allocation equilibrium, benefit consistency, and complementary characteristics of heterogeneous energy is analyzed. Meanwhile, a comprehensive alliance operation strategy is proposed based on stability, economy, and strong complementarity. The methods proposed in this study provide an effective analysis of the stability of each participant, offering a basis for decision making in cooperative, stable energy alliance generation portfolios. It also contributes to system coordination optimization theory. The alliance cooperation operation mechanism can promote efficient energy utilization and provide effective support for the development of new power systems.
