| Popis: | This paper presents results of an analysis undertaken to determine the values of design for direct normal irradiance (DNI), solar multiple and hours of thermal storage for least cost of power generation for parabolic trough based solar thermal power plants at 4 niche locations in India. Solar radiation data source of SEC-NREL has been used and annual electricity outputs have been estimated using Systems Advisor Model. For estimation of levelized unit cost of electricity, benchmark capital cost and other financing conditions suggested by the Central Electricity Regulatory Commission, Government of India have been used. Levelized unit cost of electricity has been found to be minimum for design DNI range of 600-650 W/m 2 and corresponding range of solar multiple is 1.5-1.6. Results also show that the provision of thermal storage leads to an increase in electricity output as compared to the corresponding values for plants without storage but the cost of electricity delivered increases. |
