A unified carbon linkage and low-carbon electricity price design method for a clearing electricity market
By constructing a co-cleaning model for electricity and carbon emissions and separating the components of electricity and carbon costs, and designing differentiated low-carbon electricity pricing products, the problem of the separation between the electricity market and the carbon market has been solved. This has enabled the effective transmission of carbon emission reduction signals and the rational design of electricity prices, thereby improving the economic efficiency and fairness of the market.

Abstract
The application discloses a unified electricity-carbon linkage and low-carbon electricity price design method for electricity market, and belongs to the field of electricity market and energy economy. By constructing an electricity-carbon dispatching model with the minimum sum of electricity purchase cost and carbon cost as a target, the dispatching electricity quantity, node electricity price, carbon emission and carbon cost are solved, and the electricity and carbon cost components are decomposed; according to the carbon cost component and the carbon market price, the conduction ratio and the smoothing rule are set, the conduction path and the linkage coefficient are determined, the low-carbon electricity price product including the basic electricity price, the green electricity package electricity price and the carbon credit electricity price is designed, and the green certificate market is connected to avoid repeated incentives.
