Description

technical field [0001] The invention relates to the technical field of renewable energy power supply, in particular to a cold and heat dual storage system and method based on renewable energy power generation. Background technique [0002] There are three main sources of existing electric energy, namely thermal power, hydropower and nuclear power. Among them, thermal power needs to burn fossil fuels such as coal and oil. On the other hand, combustion will emit carbon dioxide and sulfur oxides, which will cause the greenhouse effect and acid rain, and deteriorate the global environment; hydropower will flood a large amount of land, which may lead to ecological environment damage, and once a large reservoir collapses, the consequences will be disastrous. However, water power resources are also limited, and they are also affected by seasons; nuclear power is clean under normal circumstances, but in case of a nuclear leak, the consequences are equally dire. [0003] With the de...
