Investment Optimization of Incremental Distribution Network Based on Cooperative Game in the Context of Investment Liberalization

Incremental power distribution reform is an exploration of electric power reform in the natural monopoly of distribution network. By introducing multiple investment entities, the economics and operational efficiency of incremental distribution investment can be improved. From the perspective of different market entities, considering the cost of investment in different incremental distribution network investment projects, the investment model of multiple investment entities is proposed, and the investment cost models are established. On the basis of multi-energy collaborative planning, a cooperative game model of different investment models is established, and then an incremental distribution investment benefit allocation strategy is proposed based on Shapley value. The examples show that multi-agent cooperative investment can reduce the investment cost of incremental distribution network, and the allocation strategy based on Shapley value can reasonably allocate investment benefits and optimize the allocation of resources.
