Considering the diversity and comprehensiveness of the scheduling and operation strategies of the integrated energy system

the paper develops the research on multi-objective joint optimization of low-carbon economic scheduling and operation of the integrated energy system.Firstly

taking into account both economic and environmental aspects

and aiming at the minimum system economic cost and pollution gas emissions

a multi-objective and multi-constraint integrated energy system joint low-carbon economic dispatch operation model is established.Secondly

a granulation method of operation scheduling cycle based on multivariate load characteristics is proposed

and granulation calculation and multi-objective bacterial colony chemotaxis is combined to solve the problem.Finally

an integrated energy system is used as an example to verify the proposed method

which shows the rationality and effectiveness of the proposed method.
