Advanced adiabatic compressed air energy storage (AA-CAES) has excellent combined heat and power characteristics. To promote its synergistic cooperation with the power grid and heat network, this paper proposes a Multi-agent collaborative planning strategy of AA-CAES electro-thermal coupling system considering alliance stability. First, to address the issues of inadequate matching between electricity and heat load supply and demand, as well as insufficient energy interaction in the AA-CAES cogeneration system, a cogeneration system architecture incorporating electricity load, heat load, and AA-CAES is established. Second, on the basis of satisfying constraints such as equipment operation constraints and system electro-thermal balance constraints, a capacity optimization configuration model for the advanced adiabatic compressed air energy storage electro-thermal coupling system is constructed with the goal of minimizing the overall cost of the alliance. Then, a cooperative game allocation strategy based on the equalized improvement tendency index is designed, which can align the satisfaction levels of all parties, thereby ensuring allocation fairness and alliance stability, and providing feasibility for the capacity allocation planning results. Finally, case simulations were conducted using typical daily data from China’s northwestern region. The results indicate that considering the cooperative game among the power grid, heat grid, and compressed air energy storage operators can significantly reduce the alliance’s operational costs, and the proposed allocation method can ensure the satisfaction of all parties involved in the game with the allocation results.
