Description

technical field [0001] The invention belongs to the technical field of energy storage, and in particular relates to a thermal energy storage test system and an operation and control method thereof. Background technique [0002] Thermal energy is one of the important energy sources in the national economy. In the production process, a large amount of intermittent or waste thermal energy is wasted due to lack of good storage and recycling. When thermal energy is used again, other energy sources (such as electric energy, etc.) ) to produce heat energy, which causes irrational use of energy and waste of energy. Research on a material or device that can effectively store heat energy has a huge beneficial effect on energy structure adjustment and energy saving and carbon reduction. Effectively storing and recovering heat energy and rationally adjusting the energy structure will produce huge social benefits, with an overall energy-saving and carbon-reducing space of about 30%-50%....
