Estudo de um sistema híbrido eólico-fotovoltaico para o curso de Engenharia de Energia - FAEN/UFGD

Abstract

This work deals with the study on wind-photovoltaic hybrid generation. A hybrid system is characterized by containing two or more sources so that they can complement each other during a specific period, day, month or year. The studies on these systems are relevant in the current context because they are pertinent to the social and sustainable development of Brazil, since many renewable sources have intermittent characteristics. In this work, all the equipment of the laboratory of the course of Energy Engineering essential for the construction of a hybrid wind-photovoltaic system, as well as the elaboration of tables describing the components of the system and its characteristics, were made. The literature review for the study of system variables was carried out in recent works on the topic and is used as a basis to propose the topology and location for the system. The first part of the results show the levels of complementarity for the typical day and year. For the typical day was observed the nocturnal complementarity of the wind resource on the solar, but with high differential per square meter of power. For the typical year it was observed that there is complementarity of resources from the behavior of the wind resource, which is constant in comparison to the solar resource, which have observable peaks and valleys and with great power differentials per square meter. Also for the typical year, amplitude and time and energy complementarity indexes were calculated, confirming the results. In the second part of the results the topology of generators in parallel is established in an alternating current bus for the system, and it is described in tables containing the subsystems. At the end, the power generation estimates based on the photovoltaic efficiency variables of the wind turbine modules and power curve are made as a function of the wind speed, and it is also verified that it is possible to install the system behind the laboratory building of the course.
