Abstract

The invention discloses a comprehensive energy system Ex efficiency and energy efficiency evaluation method considering primary energy permeability, and the method comprises the steps: determining a total input value of each energy type at an energy supply side, including an external power network power purchase input value determined on the basis of considering the primary energy source permeability; determining the total output value of each energy type at the energy consumption side; and performing efficiency energy efficiency evaluation according to the ratio of the total output value of the energy consumption side to the total input value of the energy supply side. The method introduces efficiency to quantify the characteristics. According to the method, the external power grid power purchase input value is determined on the basis of considering the primary energy source permeability, the multi-type energy quality and the determined total input value of the integrated energy system are comprehensively considered, the two attributes of energy quantity and quality are comprehensively considered, and the energy efficiency of the integrated energy system can be evaluated more objectively and effectively.

Description

technical field [0001] The present invention relates to an integrated energy system, in particular to an integrated energy system considering the penetration rate of primary energy Efficiency energy efficiency assessment method. Background technique [0002] With worldwide attention to low-carbon, economical, high-efficiency, and sustainable development, the coordinated and optimized operation of multiple energy sources, such as cooling, heating, electricity, and gas, has become a new possible way to improve system operating efficiency. The integrated energy system involves the interconnection and coupling of cold, heat, electricity, gas and other types of energy, and includes a variety of equipment, and the overall system operation is more complicated. By building an energy network covering multiple energy fields such as electricity, gas, heat, and cold, it breaks down the technical and management barriers between heterogeneous energy sources, realizes optimal allocation ...
