Abstract

The invention provides a matrix management type solid temperature partitioned energy storage method and device. The matrix management type solid temperature partitioned energy storage method comprisesan energy storage mode and a power supply mode, wherein under the energy storage mode, a low-temperature working medium is subjected to equal-pressure heat absorption through a first module group ofa solid heat storage matrix, then, is insulated and compressed by a compressor, is subjected to an equal-pressure heat release process through a second module group, enters a turbine to be subjected to thermal insulation and expand to work externally, and returns to the first module group for being recycled; and under the power supply mode, the difference is that the working medium is subjected toequal-pressure heat absorption through the second module group, and is subjected to equal-pressure heat release through the first module group. The matrix management type solid temperature partitioned energy storage method and device solve the wind and light abandoning problem in photovoltaic power generation and wind power generation as well as the peak load shaving problem of peak-valley electricity, simultaneously conduct heating during energy storage and power supply, recycle waste heat of waste gas in another heat storage system, and improve heat-work conversion efficiency.

Description

technical field [0001] The invention relates to a method and device for energy storage and power supply, in particular to a method and device for matrix-managed solid temperature partition energy storage. Background technique [0002] The supply and demand of energy has a strong timeliness. From the perspective of electricity demand, the phenomenon of peak and valley electricity causes a large amount of waste of valley electricity. From the perspective of electricity supply, renewable energy power generation represented by wind energy, solar energy, and hydraulic potential energy is intermittent. Due to the characteristics of volatility and volatility, the power generation cannot match the needs of users. Thermal energy storage can effectively flatten the time curve of energy supply and demand. [0003] On October 11, 2017, five ministries and commissions including the National Energy Administration and the National Development and Reform Commission jointly issued the "Guid...
