Sizing Analysis of Linear Fresnel Solar Thermal Power Plant in Algeria

The aim of this work is to describe the characteristics of a 5 MWe Fresnel solar power plant at different areas of Algeria Sahara. These areas have been chosen for comparison by shifting the plant to different locations; namely Hassi R'mel, Tamanrasset, Beni-Abbes, and El Oued. Theoretical modeling allowed us to specify optimal number of mirrors. Results from simulation give an optimal number of mirrors equal to 40 mirrors. Furthermore, a sizing calculation was made while drafting a specification in order to define the different characteristics of the plant, namely insolation, “Field” system and “Receiver” system. The calculation results have been depicted for each site. Indeed, the performance varies from a site to another with DNImoy values, respectively: 788.4W/m2, 698.7W/m2, 671.7W/m2, 636W/m2, for Tamanrasset, Beni-Abbes, El Oued and Hassi R'mel sites. The surface of solar field, block number, absorber surface and power losses have also been evaluated for the same sites.
