The invention discloses a comprehensive energy system multi-level optimization method considering carbon emission, and the method comprises the steps: dividing a comprehensive energy system into threelevels: a region layer, a block layer and a local layer according to the type of a node, the local layer being located at the bottom layer, the block layer being located at the middle layer, and theregion layer being located at the top layer; establishing an optimal configuration model objective function of each level of the comprehensive energy system; establishing optimal configuration model constraints of each level of the comprehensive energy system, wherein the optimal configuration model constraints comprise an energy network trend constraint, an energy coupling constraint and a carbonemission constraint; and optimizing the comprehensive energy system based on a genetic algorithm according to the optimal configuration model objective function and the optimal configuration model constraint of each level to obtain an optimal configuration result of each level of the system. According to the invention, the collaborative planning of centralized energy supply and distributed energysupply in the comprehensive energy system can be achieved, and the flexible design requirement of the comprehensive energy system is met.
Description
technical field [0001] The present invention relates to the technical field of energy Internet planning, in particular to a multi-level optimization method for an integrated energy system that takes carbon emissions into consideration. Background technique [0002] Existing energy system planning usually proceeds from the relationship between supply and demand, and conducts special planning for each energy separately. In the actual process, various special plans interact with each other, which may cause problems such as double calculation of load, land occupation conflicts, and unreasonable energy structure. In Energy Internet planning, the planning of each energy system is integrated. How to achieve the optimal matching of energy supply and demand under the interaction and constraints of various energy sources is a key issue in the planning and design of integrated energy systems. This problem can be described as: within a limited geographical area and planning period, to ...
