ABSTRACT: Parabolic trough power plants have been developed in the integrated solar combined cycle system (ISCCS) and the direct steam generation (DSG) ,each concept has their configuration due to solar energy combination .The technology for the Solar Aided Power Generation (SAPG) is appeared for optimizing this combination in solar contribution to cycle efficiency. The target of this work is to evaluate the thermodynamic performance on solar hybrid power plants system for ISCCS and DSG concepts, in comparison for a solar to electricity efficiency. The Solar Aided Power Generation is proposed to assuming the solar contribution with evaluation method, for to calculate the generation share of the solar power system in each concept. The study shows that the DSG concept is the best hybrid system to solar-electric efficiency .Further results obtained indicate that solar contribution increase to the DSG concept proposed , in the best extraction of solar thermal for to preheat the feed water heater. The performance of the SAPG estimate the effect of the solar collector area in each concept for annual solar thermal energy.
