Description

technical field [0001] The invention belongs to the technical field of multi-objective optimization of energy systems, and in particular relates to a multi-objective optimization method and an optimization system for regional comprehensive energy systems. Background technique [0002] The comprehensive energy system integrates various energy sources such as electric energy, natural gas, heat energy, and cold energy in a certain area, and realizes the synergistic optimization and mutual assistance among various energy sources, which is helpful for improving energy utilization efficiency, promoting the consumption of renewable energy, and realizing energy conservation. Emission reduction targets are important. Traditional integrated energy system planning and operation are limited to a single optimization goal, which is not conducive to finding a balance between economic operation and environmental protection, and does not conform to the law of sustainable development.

Problems solved by technology

The optimization of carbon emissions in the previous comprehensive energy system optimization scheme is to convert the carbon emissions to the economic level for unified optimization and scheduling, which can only obtain a single optimization result, which cannot reflect an interactive relationship between carbon emissions and economics. Moreover, the optimization result of carbon emissions depends on the conversion coefficient, and a relatively ideal optimization goal cannot be obtained. Carbon emissions have become an important factor that cannot be ignored in the construction of comprehensive energy.
