Abstract
In order to diversify the electricity generation sustainably, through renewable sources, the state of Rio Grande do Norte - RN, Brazil has a high potential to explore the solar resource. Since it is located at low latitudes, the state receives high levels of Direct Normal Irradiance - DNI, ideal scenario for Concentrating Solar Power – CSP exploration, indicating that this technology might be the way to broaden the electricity generation matrix. This work presents simulations results made with the software System Advisor Model - SAM for each one of the four CSP technologies (Parabolic Trough Collector, Linear Fresnel, Central Power Tower and Parabolic Dish) to a location close to the city of Apodi, in order to determine the most viable among them, based on land area requirements, energy output and annual water consumption. The results suggest that for plants with Thermal Energy Storage (TES) systems, the most suitable technology is Linear Fresnel Receiver that presented the greatest generation per unit area in a year, 203.84 GWh/km², and the lowest water consumption per generated power, while the Parabolic Dish turned up to be the best option when not considering TES, since it presented the higher annual generation per land-use among the considered technologies.
