| 摘要 | A combined cycle power plant for frequent stops and startups comprises at least one gas turbine, a heat recovery steam generator, at least one steam turbine and a thermal energy storage and retrieval system utilizing latent heat of fusion. Phase change materials receive thermal charge from two sources: (a) renewable energy generation plants, when their production exceeds demand and (b) gas turbine exhaust heat. The thermal energy storage and retrieval system, discharges efficiently thermal energy for steam production, which keeps the at least one steam turbine preheated and ready for fast startups, thus increasing the plant's flexibility and efficiency.A novel two stage latent thermal energy storage system provides at least supercritical steam. | ||||||
