Incentive Bidding Strategies for Power Generator in the Electricity-carbon Joint Market
To optimize the bidding strategies of power generation enterprises in the electricity market,carbon market,and green certificate market,this paper proposes a bidding model for generation enterprises in the electricity-carbon joint market.Firstly,a cost function for electricity-carbon trading in power generation enterprises was established to analyze the cost transmission in the electricity-carbon joint market quantitatively.Secondly,with the objective function of maximizing the comprehensive income of power generation enterprises,and considering the coupling constraints of electricity,carbon allowances,and green certificates,a bidding model for power generation enterprises in the electricity-carbon joint market was established,and a linear reconstruction and solution method for the model is proposed.In addition,the Vickrey-Clark-Groves(VCG)mechanism design theory is introduced to propose incentive bidding strategies for power generation enterprises applicable to the electricity-carbon joint market to suppress malicious and false bidding by power generation companies.Analyzing a case in a certain area of Shanghai verified that the proposed model can improve the revenue of power generation companies and promote carbon emissions reduction,providing references for power generation company portfolio trading in the electricity-carbon joint market.
