液态空气储能是一种新的、成熟的储能技术，它有可能增加可再生能源在电网中的渗透率，同时通过能源价格套利获得收入。本文提出了一种在GB实时电力市场中基于价格套利操作的液空储能经济可行性评估方法。本文设计的套利算法在不同的运行策略下每半小时确定一次价格阈值，根据该阈值对系统进行充电、放电或待机的决策，并对系统不同部件尺寸的最优设计进行评估。结果表明，12种预测策略是最优的运行策略，在该策略下，200 MW的LAES系统能够获得正的净现值GB 43.8 M，在不使用余热的情况下，200 MW系统的回收期可长达36.9~39.4 年，这取决于所采用的套利策略。而采用150 °C的余热，回收期可缩短至8.7~9.8年 。
Liquid air energy storage is a novel proven technology that has the potential to increase the penetration of renewable on the power network and in the meanwhile to obtain revenues through energy price arbitrage. This paper proposes a methodology to evaluate the economic viability of liquid air energy storage based on price arbitrage operations in the GB real-time electricity market. The arbitrage algorithm designed in this article determines price thresholds every half hour under different operation strategies and according to which, decisions are made for the system to charge, discharge or stand by, and the optimal design of the size of different components for the system are also evaluated. Results suggest that the 12 prognostic is the best operating strategy, and under which a 200 MW LAES system is able to achieve a positive net present value of £43.8 M. Without using waste heat, the payback period for a 200 MW system can be as long as 36.9 to 39.4 years, depending on which arbitrage strategy is applied. However, with waste heat of 150 °C adopted, the payback period can be shortened to 8.7–9.8 years.
