Análisis dinámico de un sistema fotovoltaico flotante para el embalse de mazar : análisis para la zona 3 – cota inferior.

Abstract

Currently, the demand for renewable resources has increased. Photovoltaic energy is an attractive renewable resource for Ecuador for three reasons: geographic location, solar radiation, and energy complementarity in times of drought. The Mazar reservoir has a large surface area of water that can be used for the installation of a floating photovoltaic plant (FPV), which consists of a floating structure, photovoltaic panels, and a mooring system. During the year, the rain, dry season, flood, and drainage generate large variations in the water level (elevation) in the reservoir. Traditional mooring systems are not capable of controlling the movement of an FPV with these variations in water level. This project proposes a conceptual model of an FPV with a passive mooring system, which adapts to elevation variation and guarantees stability under environmental loads. The component begins with a topographic analysis of zone 3 of the Mazar reservoir for the lower level, followed by the geometric dimensioning of the FPV. A preliminary geometry for the mooring system is proposed and environmental loads are analyzed. A numerical model is developed and various, simulation scenarios are conducted considering variation of the wave spectrum, variation of inertial parameters of submerged bodies, and variation of the mooring pattern. Finally, the dynamic responses and stability of the model are analyzed. The results show that a mooring system composed of pulleys, mooring lines, and submerged bodies restricts movement and guarantees FPV stability for the lower elevation. The oscillating displacement of the FPV depends on the gravity of the inertial parameters of the submerged bodies of the mooring system, it also depends to a lesser extent on the arrangement and direction of the mooring lines.
