The invention relates to a method for modeling and planning a multi-source heterogeneous full renewable energy thermoelectric storage coupling system, the method comprising the following steps: (1) constructing a physical structure of a multi-source heterogeneous full renewable energy thermoelectric storage coupling system; (2) Modeling of the integrated equipment of the multi-source heterogeneous all-renewable energy thermal-electricity-storage coupling system; (3) establishment of the optimization planning model of the multi-source heterogeneous all-renewable energy thermal-electrical-storage coupling system; (4) based on the actual calculation example The proposed optimization planning model is solved and analyzed, and the optimal capacity ratio results of system integration equipment are obtained. Compared with the prior art, the present invention fundamentally reduces the use of fossil fuels and reduces environmental pollution; secondly, while increasing the penetration rate of renewable energy in the energy system, the utilization efficiency of renewable energy is improved; The annual economic cost of the system is used as the objective function, which improves the economics of the multi-source heterogeneous full-renewable energy thermal-electrical-storage coupled system.
Description
technical field [0001] The invention relates to the technical field of comprehensive energy system application, in particular to a modeling and planning method for a multi-source heterogeneous full renewable energy thermal-electricity-storage coupling system. Background technique [0002] Energy is the foundation for human survival and development, the guarantee of sustainable social development, and the lifeblood of the national economy. With the in-depth development of industrialization, fossil energy is increasingly in short supply, and ecological and environmental problems are becoming more and more serious. In the future, the energy industry shoulders new missions such as improving energy efficiency, ensuring energy security, promoting new energy consumption, and promoting environmental protection. The major transformation of energy production and consumption patterns requires changing the traditional energy system construction path and development model and building an...
