Abstract

The invention discloses an optimization method of a comprehensive energy system containing electricity-to-gas and carbon capture equipment. The energy equipment of the comprehensive energy system comprises a wind turbine generator, a photovoltaic unit, a cogeneration unit, a micro gas turbine, an absorption refrigerator, electricity-to-gas equipment, carbon capture equipment and an electric refrigerator. The optimization method of the integrated energy system comprises the following steps: acquiring an initial carbon emission distribution limit, an actual carbon emission amount and a carbon emission amount price of the integrated energy system, and fuel cost and power purchase cost of energy equipment; obtaining carbon transaction cost by using a carbon transaction cost model of the integrated energy system; obtaining the operation cost by using the operation cost model of the integrated energy system; and on the basis of the carbon transaction cost and the operation cost, the optimal scheduling model is solved by adopting YALMIP and GUROBI, and the lowest comprehensive operation cost is obtained. According to the optimization method disclosed by the invention, the consumption capability of renewable energy sources is improved, and the carbon emission and the operation cost of the integrated energy system are reduced.

Description

technical field [0001] The invention relates to the technical field of power system optimization operation, in particular to an optimization method of a comprehensive energy system including power-to-gas and carbon capture equipment. Background technique [0002] In the face of energy crisis and climate warming, renewable energy is widely used to reduce environmental pollution. Renewable energy integration becomes more critical due to the heat load requirements provided by combined heat and power (CHP) units. At the same time, extensive use of fossil fuels will release a large amount of carbon dioxide, leading to the greenhouse effect. Optimizing the integrated energy system (IES) can improve the efficiency of renewable energy utilization and the flexibility of system operation. Improving the consumption of renewable energy and environmental pollution is imminent. [0003] Carbon capture system (CCS) technology is widely used in coal or gas-fired power plants. CCS captur...
