Description

technical field [0001] The invention relates to the field of power system operation and control, in particular to a multi-energy system homogeneous coupling modeling method. Background technique [0002] With the gradual depletion of fossil energy and the ensuing environmental problems have become increasingly serious, countries around the world have begun to vigorously develop renewable energy. Due to the randomness and intermittent nature of most renewable energy power generation, large-scale grid integration will have an impact on the stable operation of the grid. [0003] In the modeling and analysis of traditional energy systems, wind, light, water, gas, fire, storage and other energy forms are generally treated separately, and the interaction between different energy sources is often ignored or approximated. Combining various forms of energy such as wind, light, water, gas, fire, storage, etc., overcomes the instability of a single wind power or photovoltaic power gen...
