The method comprises the following steps: acquiring operation data and system equipment parameters of the integrated energy system; establishing a new energy prediction error model, and solving a prediction error; establishing a system equipment operation model; setting a power system constraint condition, a cold and thermal system constraint condition and a hot water system constraint condition; linear transformation is carried out; respectively establishing a system operation cost function model, a prediction deviation penalty cost function model, a carbon emission cost function model, a green certificate transaction cost function model, an energy storage battery life cost function model and a comprehensive energy system total cost objective function model; and solving to obtain a scheduling result. According to the method, volatility and randomness of wind power are fully considered, carbon emission to the environment is reduced through carbon transaction and green certificate transaction, and the optimal solution considering the total cost of the comprehensive energy system and the carbon emission of the environment can be effectively obtained.

Description

technical field [0001] The invention relates to an energy dispatching method, in particular to an optimal dispatching method for an integrated energy system. Background technique [0002] With the increasing demand for energy in the world, the global ecological environment has been severely damaged. Reducing carbon emissions and improving energy efficiency have become the mainstream research directions of the world's energy. [0003] Through the optimal dispatch of energy, the utilization rate of energy can be improved and carbon emissions can be reduced. However, the existing comprehensive energy system research is generally thermoelectric and cold-thermal electric systems, and less renewable energy is involved. The scope of the load model is relatively general and not specific, and the complex model is not conducive to solving. [0004] Due to the influence of weather and environment, the output of renewable energy has the characteristics of volatility and uncertainty, ...
