Abstract
This work presents a review of the literature on the study of electricity generation using dish/Stirling Concentrator. Firstly, a brief description of the main components of this solar system is given, which include the Stirling engine and some of its parameters. Following, the CSP (Concentrated Solar Power) is analyzed, and its most common technology is presented. The SPD (Solar Parabolic Dish) power plants are presented, revealing the advantages of the dish/Stirling system among all solar technologies. The dish/Stirling system has proven to be an attractive alternative to produce electricity, especially due to its high efficiency, up to 30%, and its unique design that allows wide flexibility in the choice of fuel. It is also important to note that the dish/Stirling system can be used in isolated locations, where the conventional power grid is not available. This use would mainly benefit the poorer and isolated regions. Although the parabolic trough is the dominant technology of producing electricity using solar concentrator, mainly due to its lower cost, the dish/Stirling system promises to overcome these challenges by reducing capital and maintenance costs and becoming competitive compared with other solar technologies in a few years, especially due to new technological improvements, new developed technologies, and large-scale production.
