Abstract: The implementation of carbon emission trading will increase the pressure of power enterprises to reduce emissions， and the phenomenon of "three discards" will also enhance the demand of clean energy across provinces and regions， which will profoundly change the market game behavior of power generation enterprises. This paper proposes a low-carbon incentive clearing method and discusses an optimal bidding strategy for the main subject of trans-provincial power trading， in which the constraint of carbon quota and the obstruction of clean energy are taken into account at the same time. Firstly， the market structure under the cooperation of carbon trading and power generation right trading is established， and synergistic influence between the carbon trading and power generation rights is clarified. Secondly， monetizing the carbon emission reduction benefits of clean energy power generation， a low-carbon incentive clearing model of trading center is constructed on the basis of maximizing the sum of economic utility and carbon emission reduction benefits of trading. Meanwhile， the competitive decision model of heterogeneous power producers is constructed on the basis of profit maximization. Numerical examples verify the effectiveness of the proposed clear model and bidding decision model. The results show that the proposed clear model can promote the trans-province consumption of clean energy；the established game model can enable each generator achieving optimal profit and the market reaches equilibrium， which realize the joint optimization of the clearing target.
