The construction of a spot market which is suitable for clean energy consumption is a focus of China's current power market. A spot market trading mechanism with bilateral reserve markets and green credentials transactions is proposed. First, a green certificate trading mechanism is introduced to promote wind power grid-connected transactions. Combined with the current domestic clean energy market situation, this paper presents a green certificate mandatory trading quota system and determines the green certificate transaction amount and pricing model; second, to reduce the high assessment fee of wind power due to bid bias, a bilateral reserve market is introduced in which wind power suppliers participate in the purchase and sale of electricity. Under this market mechanism, the thermal power supplier is regarded as a supplier of trading power to play with the wind power supplier in the purchase and sale game. The post-deformation model which is based on the Cournot model and the Rubinstein model are employed to determine the transaction volume and transaction price of the bilateral reserve market. Then, a function model is used to determine the profit of the generator by simulating the actual output of wind power through Monte Carlo simulation and scene reduction technology. The simulation results show that the wind power suppliers who participate in the trading between the market and the bilateral reserve market can reasonably avoid the deviation penalty, and the profit of each generator is improved. This verifies both the logic and effectiveness of the proposed model at the same time. This work is supported by National Natural Science Foundation of China (No. 51807125).
