Abstract: A solar thermal power system includes a solar receiver, and a thermal energy storage arrangement having thermal energy storage fluid to be circulated through the solar receiver to store thermal energy. The system includes a multistage steam turbine operable on variable pressure steam generated by a steam generator arrangement, by utilizing the thermal energy storage fluid. The arrangement includes an economizer section, an evaporator section, and a superheater section communicably configured to utilize the heat of the hot thermal energy storage fluid to generate and supply the variable pressure steam to the turbine. The system includes a recirculation line configured around the economizer section to recirculate the heated water to an inlet of the economizer section, increasing pressure range of the variable pressure steam in the arrangement.

Abstract: A solar thermal power system can include a solar receiver steam generator, a thermal energy storage arrangement utilising a thermal energy storage fluid, and a multistage steam turbine for driving an electrical generator to produce electrical power. The solar thermal power system has a first operating mode in which steam is generated by the solar receiver steam generator and is supplied both to the thermal energy storage arrangement and to a high pressure turbine inlet of the multistage steam turbine. In a second operating mode, steam is generated by recovering stored thermal energy from the thermal energy storage fluid of the thermal energy storage arrangement for injection into the multistage steam turbine at a location or turbine stage downstream of the high pressure turbine inlet.
