Electricity Price Considering Cross-subsidy and Carbon Emissions with Dual Carbon

To cope with the conflict between the goal of “carbon neutral and carbon dioxide peaking” and the development goal of electricity price, as well as the problem of excessive power cross subsidies in China, firstly, from the perspective of region and users the cross subsidy was classified. Secondly, a calculating model of cross subsidy scale was constructed. Thirdly, taking the maximizing social welfare as the objective and considering the carbon emission constraint, an optimal electricity price mechanism was designed. Finally, the results of the computing example based on actual data of a certain provincial power grid show that overall social welfare can be improve by accepting electricity prices considering carbon constraints.
