摘要
储能技术作为一种解决电网调峰问题的方法得到了长足发展,但现有技术均存在一定的限制。构建了一种简单超临界CO2循环储能装置,通过热力学计算,储能效率达到64.39%,能够实现电网削峰填谷及节能减排功能;同时对不同释能功率下的装置进行了经济分析,获得了其购置成本、回收周期随着装置功率等级变化的波动趋势。本研究为同类储能装置设计及经济性分析提供了一定的研究基础。
As a method to solve the peaking modulation of power networks,energy storage technology has been continually developed,but the existing technologies have certain limitations.A simple energy storage device based on supercritical carbon dioxide cycle is constructed.The thermodynamic calculation of the device shows that the distributed energy storage device can achieve an energy storage efficiency of 64.39%,and can realize peak shaving,energy saving and emission reduction in the power network.At the same time,the economic analysis of the device under different power release levels is carried out,and the fluctuation trend of the acquisition cost and recovery period with the power level of the device is obtained.This research provides a basis for the design and economic analysis of similar distributed energy storage devices.
