Effect of wind speed on the efficiency of the integrated solar combined cycle power plants SPP I in Algeria

Abstract

The use of Concentrating Solar Power, ‘CSP’ with hybrid system for electricity production promises to be one of the most viable options to replace fossil fuel power plants. Indeed, research and development activities on its basic subsystems have been booming rapidly since 1980s. The integration of parabolic trough solar technology with combined cycle power plant technology is referred to as integrated solar combined cycle systems, ‘ISCCS’, has been proven a great interest in the development of renewable energies and more particularly in technical and economic assessment of solar power plants. Net solar electricity, electricity production, fuel consumption, Thermal efficiency, environmental considerations, investment and Operations & Maintenance, ‘O&M’ costs are the most important parameters to evaluate suitable performance. The central SPP I under the climate of Hassi R’Mel is a hybrid plant consists of a conventional combined cycle (TV-TG) associated with a solar field without thermal storage. This study shows that an ISCCS saves 20 millions $ in fuel consumption and reduces about 1 million ton in CO2 emission during 30 years operating period.
