CCHP MICRO-GRID STRUCTURE INCLUDING COMPRESSED AIR ENERGY STORAGE AND OPERATION METHOD THEREFOR

摘要

A CCHP micro-grid structure including compressed air energy storage and an operation method thereof. The micro-grid structure comprises: a renewable energy supply device, an adiabatic compressed air energy storage system and a combined cooling, heating and power supply unit consisting of a gas generator and an absorption refrigerator. The combined cooling, heating and power supply unit takes natural gas as fuel. The adiabatic compressed air energy storage system compresses air to generate heat energy, and the heat energy is stored or directly supplied to heat consumers by means of the adjustment of three-way valves (1, 2, 3, 4, 5, 6, 7, 8 and 9), and the heat energy of different heat sources is absorbed according to the operation mode of the system when the energy is released.
