Research on Low-carbon Integrated Energy Microgrid Multi-objective Optimal Operation Method

The integrated energy system is of great significance in realizing the comprehensive utilization of multiple energy sources, improving the utilization rate of new energy and reducing carbon emissions. Aiming at the problem that the types of research equipment and models for optimal operation of the integrated energy system are less and the objective function of optimal operation is single, a multi-objective optimal operation method of integrated energy microgrid with multi-energy complementary is proposed. Firstly, the optimization objective function considering the operating cost, carbon emission and primary energy consumption and system constraints are established. Secondly, the multi-objective operation optimization of the integrated energy system is carried out based on a weight analysis method. The calculation examples show that the integrated energy system constructed in this paper can operate effectively, and the optimized weight ratio can significantly balance each objective function.
