Electricity is the prerequisite and important guarantee for the progress and development of human society. It has an important position and role in the national energy strategy. Increasing the share of renewable energy generation in electricity production has a broad and far-reaching impact on the sustainable development of China’s economy and society. Influences. However, due to the intermittent and instability of renewable energy itself, in order to avoid large-scale renewable energy generation from impacting the power grid, the scale of renewable energy generation and grid-connected power are limited to a certain extent. Advanced Adiabatic Compressed Air Energy Storage (AA-CAES) technology uses a heat storage device (TES) to store compressed heat, eliminating the dependence on fossil fuels and achieving “zero emissions.” At present, AA-CAES technology is considered as an energy storage technology with great market development potential. The paper calculates the performance of the system given the input of the air compressor and the output power of the turbine; analyses the parameters such as the storage pressure ratio, convective heat transfer coefficient, and energy release interval time for energy storage density, cycle efficiency and other systems The influence of performance parameters; reveals the temperature and pressure changes of the gas storage chamber with time during a single cycle.
