Optimization of Solar Terrestrial Power Production Using Heat Engines

Abstract

Mathematical model and computer programs have been developed for the analysis of the economic performance of a terrestrial solar power system using heat engines. Various combinations of cycle, collector, engine, storage system, and sink have been studied and the influence of design parameters on power costs examined for both the steady and unsteady state cases. Typical minimum power costs under central Australian conditions for units of 12 kw capacity at current levels of materials and labor costs range from 7 to 47 U. S. cents per kwh, according to the specific design of installation.
