Rolling Clearing Model of Electric Carbon Joint Market Based on Centralized Carbon Trading Mechanism

In the context of the “30·60” carbon peak and carbon neutrality goals, China has launched carbon emission trading nationwide, which is currently only in the power generation sector. However, due to the different physical constraints of the carbon market and the electricity market on commodity trading, the trading time scale is quite different, and it is difficult to integrate effectively. Therefore, in order to better discover the price signals of carbon traded commodities by unifying the trading time scale of the carbon joint market, this paper proposes a clearing model of the electricity carbon joint market considering the unit load rate-carbon emission intensity curve according to the characteristics of the current trading modes of the electricity market and the carbon market. Through the centralized carbon trading mechanism and the rolling liquidation of the electric carbon joint market, the time-segment carbon price and the benefits of the joint market are maximized.
