Large-scale 5G base stations (BSs) confront high operating costs under traditional power supply. In order to coordinate the green economy transformation of energy structure on the supply side of 5G BSs with the improvement of flexibility regulation capability on the grid side. this paper proposes a hybrid game optimization dispatch method of active distribution network (ADN) with large-scale PV integrated 5G BSs leasing shared energy storage (SES) system. First, a master-slave game optimization model is constructed with ADN as master body and 5G BS coalition as slave body, and is solved by dichotomy method to derive optimal time-sharing tariff strategy and operation strategy of 5G BS alliance. Secondly, considering the cost sharing among entities of 5G BS coalition, an cooperation game operational model is constructed based on the Nash bargaining theory, and then equated into 5G BS coalition operation benefit maximization subproblem and power transaction payment bargaining subproblem, and is solved by alternating directional multiplier method (ADMM). Finally, the simulation results verify the effectiveness of the proposed method.
