Thermo-economic analysis of the integrated bidirectional peak shaving system consisted by liquid air energy storage and combined cycle power plant

Natural gas peak shaving power station with gas-steam combined cycle is widely used to meet the demand of peak load regulation of the power grid. However, the exhaust heat of the system and the high-grade cold energy from the nearby liquified natural gas terminal are not fully utilized. Liquid air energy storage is a load leveling method suitable for grid scale but the system efficiency needs to be further improved. Therefore, a system that...
