Speech Title: Progress in concentrated solar power technology with parabolic trough collector system

Abstract: Advanced solar energy utilization technology requires high-grade energy to achieve the most efficient application with compact size and least capital investment recovery period. Concentrated solar power technology has the capability to meet thermal energy and electrical demands. Benefits of using CSP technology with parabolic trough collector system include promising cost-effective investment, mature technology, abundant operational experience, ease of coupling with fossil fuels and other renewable energy sources. The theoretical framework of the CSP plant with PTC technology and the progress in thermal deformation restrain methods for tube receiver were reviewed as the deflection of tube receiver and rupture of glass covers were frequently observed during test and application. Besides, commercial CSP plants with PTC system in the world including those that are operational, under construction, and announced were also listed. Further developments and future prospects for CSP plants with PTC systems would focus on how to increase the operating temperature.
