Performance Analysis of a Novel Cascade Integrated Solar Combined Cycle System

This paper proposed a novel cascade integrated solar combined cycle system, in which concentration solar collector (e.g. parabolic troughs) as direct steam generator and non-concentration collector (e.g. evacuated tubes) are hybrid with combined cycle power plant. Cascaded integration of solar into the combined cycle is achieved in the proposed system. This study analyzes the thermodynamic and economic performance as well as energy conversion characteristics of the proposed hybrid system. The result indicates that the low-cost and high-efficiency solar heat-to-power conversions for this hybrid system are achieved.
