Abstract: The "double carbon" goal promotes the development of China's energy sector in the direction of

green，low-carbon，safe and efficient. In order to improve the penetration of renewable energy such as scenery，

stabilize the diversified load fluctuation on the user side，improve energy utilization efficiency and develop safe，lowcarbon and clean energy，based on the carbon trading mechanism，the optimal operation model of micro energy grid （MEG）considering comprehensive demand response was constructed，and the CPLEX solution toolbox was used to solve the model for different scenarios. The results display that the operation cost of MEG system without considering carbon trading and comprehensive demand response is ¥18 853.30，while the operation cost of MEG system after considering carbon trading and comprehensive demand response is ¥15 540.57，which decreases by ¥3 312.73. At the same time，the peak-valley difference of electric，heating，cool and air conditioning load on the user side decreases by 5.9%，3.4%，10% and 9.13%. The results show that the established MEG optimal operation model can further improve the operation economy of the system and effectively reduce the carbon emission of the system.
