Performance of medium-power Fresnel Concentrator solar plant in Algerian sites

摘要

The aim of this work is to characterize a 5MWe Fresnel solar power plant at different areas of Algeria Sahara. These areas have been chosen for comparison by shifting the plant in different locations; namely Hassi R'mel, Tamanrasset, Beni-Abbes, and El Oued. Theoretical modeling has allowed the determination of mirror optimum number to avoid shadowing effects, blocking and cosine effect. Minor optimum number was estimated at 40 mirrors. Furthermore, a simulation was carried out on a time scale, regarding insolation, 'field' and 'receiver' systems. The simulation results are depicted on annual basis. Efficiency, annual energy generation and the cost per kWh are evaluated. Indeed, the calculation of efficiency differs from a site to another with values of 15.7%, 11.8%, 11.6% and 10.4%, respectively for Tamanrasset, El Oued, Beni-Abbes, Hassi R'mel. Thermal performances, technical and economic results have been also evaluated for the said sites.
