Due to the difference of the physical constraints of traded goods and trading time scale in the electricity market and the carbon market are different, it was difficult for the two markets to integrate effectively. Aiming at the problem, a rolling clearing model of the electro-carbon joint market based on the variable carbon emission intensity and the centralized carbon trading mechanism was proposed. In the proposed model, the interaction between the electricity market and the carbon market was enhanced by considering the carbon intensity and load rate interval of the unit. Meanwhile, the rolling clearance of the joint market based on the centralized carbon trading mechanism reduced the trading time scale of the carbon market to synchronize with the electricity market, making it's better to found the value of carbon emission rights in different periods. With the further reduction of China's carbon emission baseline value and the increase of new energy penetration rate, the impact on each unit was analyzed by simulation examples. It was verified that in the proposed model, with the reduction of the carbon emission baseline value, the average carbon cost of high-carbon emission units increased by 46%, the average carbon income of low-carbon emission units increased by 27%, and the increase in the penetration rate of new energy units reduced the average carbon cost of the large-capacity thermal power units by 5. 53%. Therefore, the proposed model could effectively promote the transformation of the clean direction of the system. Compared with the traditional stepped carbon pricing mechanism, the average carbon cost of high-carbon emission units in the proposed model was reduced by 6. 13%, which could indirectly improve the enthusiasm of high-carbon emission units to participate in the carbon market.
