Abstract: New requirements for energy consumption on the user side have been put forward by the continuous promotion of the "carbon peaking and carbon neutrality" goal, and the traditional electricity consumption methods will gradually develop towards low-carbon and clean. In order to meet the low-carbon electricity demand of users, a low-carbon operation strategy was proposed for different electricity groups of users on the user side. Firstly, the characteristics of user electricity consumption behavior were analyzed, and combined with the theory of carbon emission flow of the lossy network, a low-carbon operation power use strategy model was built, meanwhile, an economic evaluation index was formulated. Secondly, based on the characteristics of node carbon potential changes, the ant-lion optimization algorithm was used to solve the proposed model, accurately obtaining the low-carbon power strategy of different users. Finally, the proposed model and method were simulated and analyzed by using the IEEE14 node system to further verify the effectiveness of the proposed low-carbon operation power strategy.
