Abstract:
1. A method for power generation using solar thermal power, comprising: heating a first thermal transfer fluid using a first solar collector; heating a second thermal transfer fluid using a second solar collector to a temperature lower than the temperature of the first thermal transfer fluid heated by the first solar collector; transferring heat to a first working fluid within a steam power generation cycle using the first thermal transfer fluid; and transferring heat to a second working fluid within an ORC power generation cycle using the second thermal transfer fluid and the first working fluid, wherein transferring heat comprises using the second thermal transfer fluid to superheat a vaporized second working fluid, further comprising preheating the second working fluid with either the first working fluid or second thermal fluid; vaporizing the preheated second working fluid with the first working fluid; and superheating the vaporized second working fluid with the second thermal transfer fluid.
