Abstract

High fossil fuels price and stringent environmental regulations pose the electrical generation industry new challenges. Since the beginning of the 1980s, large-scale grid-connected Concentrating Solar Power (CSP) has been developed in regions with a strong direct normal irradiation (DNI). CSP allows converting solar power into heat before it can be used to power a turbine and generate electricity. Using the System Advisor Model (SAM) software, we simulate two linear Fresnel solar plants located in Ponce, Puerto Rico. The first a Direct Steam Generation (DSG) plant with no fossil backup or thermal energy storage. The second a Linear Fresnel plant with molten salts as Heat Transfer Fluid (HTF) as well as the storage medium for a 4-hour storage system. We compare these two and present the results in this paper.
