This study considers China's new electricity reform and related policies as a prerequisite, makes depth analysis of the power generation and sales companies bidding model, and puts forward the game strategy of single sales company and multiple power producers that considered network constraints based on the principle of dark auction in game theory. Considering the problem of transmission obstruction, a two‐layer optimisation model is established. The lower level makes the maximum profit of the generator as the objective function, using the probability function to describe the quotation behaviour of the competitors, using the average match method to solve the bidder's bid. According to the underlying information, the upper single sales company uses linear programming methods to give low‐cost unit queuing priority, combined with grid operating constraints to calculate the minimum purchase cost. Through the upper and lower models, interactive solution can improve the transaction success rate and reduce the occurrence of transmission congestion. Finally, the modified IEEE14 node example is used to analyse and verify.
