AI Technical Summary
The energy utilization rate of existing electric thermal energy storage methods is low, and there is an urgent need to improve the energy utilization rate and thermal storage capacity in the electric thermal energy storage process.
The gaseous working fluid is initially heated by the waste heat device in the park, and then the power of the park users' electricity is used to do work through the compressor. The gaseous working fluid releases heat energy and is stored in the heat storage device. The compressor with high temperature resistance and carbon-based heat storage body are used to ensure that the working fluid temperature is not lower than 550℃.
It improved the energy utilization rate and heat storage capacity during the thermal storage process, achieved high-temperature thermal storage of no less than 550℃, and enhanced the power and heat mutual support capacity and power capacity utilization rate within the park.
