摘要：

With the increasing penetration rate of distributed energy resources in the distribution network ，appropriate market mechanism can promote the local consumption of distributed energy resources. A bi-level optimization framework for local peer-to-peer （P2P） trading coordinated with centralized market is constructed. The upper-level is the nonlinear Nash bargaining model of local P2P trading and the lower-level is the linear clearing model of centralized market. A two-stage solving method is proposed to solve the model. In the first stage，the upper-level model is simplified to minimize the total operation cost of local market，while the lower-level model remains unchanged. By the Karush-Kuhn-Tucker condition-based equivalent substitution，the first stage optimization model is transformed into a mixed-integer second-order cone problem for solving. The second stage is the payment benefit maximization problem，which can be solved directly by inequality of arithmetic and geometric means. A combined transmission and distribution system is taken as an example for simulation analysis and validity verification. The results show that the proposed model can promote the local consumption of distributed energy resources，improve the income of local market players and ensure the safe operation of distribution network. © 2023 Electric Power Automation Equipment Press.
