Cooperative Operation Strategy of Electricity-Carbon Market Considering Randomness and Correlation of Electricity-carbon Price

The electricity-carbon market are connected through the price transmission mechanism. The risk of the electric-carbon market's cooperative functioning will be caused by the variation in the price of carbon and how it interacts with the price of energy. As a result, a cooperative marketing strategy for electric-carbon is put forth that takes the price of electric-unpredictability carbon's and correlation into account. Firstly, the interaction mechanism of the electric-carbon market was analyzed through the demonstration project of the collaborative operation of the international electric-carbon market. Secondly, the conditional value-at-risk function was used to calculate the potential risks posed by the randomness of the electric-carbon price, and the Copula function was used to model the joint probability distribution of the electricity price and carbon price to describe the correlation between them. Aiming at the maximum profit of generators, a generator bidding model considering the randomness and correlation of electric-carbon price was established to characterize the cooperative operation state of the electric-carbon market. The example simulation results show that the bidding model considering the randomness and correlation of the electric-carbon price can improve the revenue of generators and reduce the carbon emissions of electric energy.
