Description

technical field [0001] The present invention relates to the field of integrated energy systems, park-level integrated energy systems, energy stations and other fields of multi-energy coupling link modeling, and in particular relates to a system that considers energy quality hub model. Background technique [0002] In order to solve the increasingly severe environmental problems, my country has proposed the goal of "carbon peaking and carbon neutrality". As the focus of carbon emissions in the energy field, building a clean, efficient and sustainable energy system has become an important means to solve current environmental problems. The integrated energy system couples multiple energy forms such as electricity, gas, heat, and cold, and reduces losses and improves energy efficiency through multi-energy complementarity, thereby achieving the goal of energy conservation and emission reduction. [0003] The coupling of many forms of energy brings certain difficulties to the u...
