Abstract: In the context of low-carbon power, the participation of large power system in the carbon market and green certificate market has become an important means to promote energy conservation and emission reduction. To further reduce the carbon emissions level of energy storage-multi energy complementary system (ES-MECS) and improve the operational economy of the system, an ES-MECS optimization scheduling strategy is proposed under the integrated carbon green certificate trading (ICGCT) mechanism. Firstly, physical modeling of ES-MECS, after analyzing the operating modes of the carbon emission trading (CET) market and the green certificate trading (GCT) market, ICGCT mechanism is established for the mutual conversion of carbon emission rights and green certificates. Secondly, an ES-MECS optimization scheduling model is established with the objective of minimizing the overall operating cost, which consists of ladder-type carbon trading cost, energy purchase cost, and green certificate trading benefit. Finally, data analysis is conducted using examples, and the impact of factors such as the basic transaction prices of green certificate trading and carbon trading on system operation is analyzed to verify the effectiveness of the proposed strategy. The final result shows 0.35 % reduction in overall operating cost and 5.03 % increase in total revenue, providing ideas for optimizing the operation mode and strategy of regional power grids.
