A cooperative game based fair-efficient trading model in global green energy market

This paper considers that many countries are connected in a global green energy market. The purpose of the work is to propose a trading model that guarantees the efficiency to maximize total system gains and the fairness of cooperative gain allocation to ensure trading stability. A cooperative game based trading model is designed for the market. In the model, a dynamic pricing rule is proposed to decide which countries are allowed to participate in trading, so as to maximize the cooperative gains. A Shapley value based method is used to fairly allocate the cooperative gains based on the marginal contributions of countries. Experimental results show that the proposed model can achieve both efficiency and fairness, which encourages countries to participate in trading more actively.
