Abstract
The design of the solar energy conversion systems is essentially determined by the geographic location of the solar power plant and the energy demand. The geographic location establishes the primary climatic factor at design of the solar energy conversion systems, because the solar irradiation determines the energy available at the conversion system. The energy demand is another primary factor at the design of the energy conversion systems because it determines the electricity to be generated by solar power plant. The methodology of Dish-Stirling solar power plants sizing applied at this article consisting of a mathematical modeling of the geometrical and thermal performance of the Dish-Stirling system. This methodology was applied to develop a computational program to sizing the Dish-Stirling system and calculate the electricity generated, from the energy demand, the sizing the Dish-Stirling power plant is determined. The case study develop consists on design of Dish-Stirling power plants at two Brazilian location with different availability of solar irradiance to attend the same energy demand. This case study develops an economic analysis of the financial impacts by the geographic location of Dish-Stirling power plants, as well the feasibility analysis and financial sensitivity analysis of solar power plants.
