Synopsis:
Energy plays an important role in development of a country. Limited fossil resources and environmental problems associated with them have emphasized the need for sustainable energy supply options that use solar energy. Solar energy can be used for wide range of applications such as power generation; potable water production; Cooling and Heating. Concentrating solar power (CSP) systems such as linear Fresnel reflector, parabolic trough collector, power tower and parabolic dish collector have emerged as matured energy technologies. The CSP systems can generate high temperature heat for electricity and water production in most effective way. We have carried out an extensive analysis of solar thermal systems such as parabolic dish, trough and linear Fresnel systems for energy production. Solar energy can be used as either a supplementary energy source in the existing conventional steam power plants or standalone solar power plant. There are various options to use solar energy in conventional steam power plants like feed water heating, super-heating/reheating of steam, and air preheating. The reduction of coal consumption about 14–19% is observed by substituting turbine bleed streams to all the feed water heaters including deaerator with solar aided feed water heating system. The cost of electricity generation of solar based power plant is depends on the performance of solar power plant and capital and operating and maintenance cost of the plant. Therefore, evaluation of thermodynamic performance of a solar power plant along with its environmental impact and economic analysis is necessary for a detailed techno-economic assessment. The levelised cost of electricity generation of solar thermal power plant for Indian conditions is found about Rs.11.00/kWh.
