Previous issue date: 2017-06-23 / A escassez dos recursos naturais e a busca por fontes de energia alternativa
promovem uma r?pida mudan?a na matriz energ?tica mundial. Dentre as fontes de
energia renov?veis a energia solar ? a mais promissora, visto que ela apresenta a
maior taxa de crescimento na atualidade. Pesquisadores de todo o mundo t?m buscado
formas de viabiliza??o do seu progresso, desenvolvendo tecnologias com maior
efici?ncia e menor custo. Como forma de contribuir para o avan?o desta tecnologia,
neste trabalho prop?e-se o desenvolvimento de uma microgrid em corrente cont?nua
interligando os pain?is fotovoltaicos atrav?s de um dispositivo com estrat?gia de
rastreamento elaborada a partir do m?todo perturba??o e observa??o, que atuar?
junto a um circuito eletr?nico de pot?ncia e um sistema de comunica??o sem fio para
acompanhamento da gera??o individual. Simula??es foram desenvolvidas para a escolha
da topologia de liga??o e compara??o entre o m?todo de controle proposto e o
tradicional, atribuindo-se diferentes n?veis de entrada e constatando-se graficamente
as respostas de sa?da. Com o projeto e desenvolvimento dos circuitos, firmware e
placa de circuito impresso do dispositivo proposto, p?de-se efetuar experimentos
para constatar sua capacidade de convers?o de energia e verificar as respostas dos
m?todos de controle supracitados, colocando-o como uma poss?vel op??o vi?vel e
somando uma pequena contribui??o ?s tecnologias embarcadas na ?rea de energias
renov?veis. / The scarcity of natural resources and the search for alternative energy
sources promote a rapid change in the global energy matrix. Among the renewable
energy sources solar energy is the most promising, since it has the highest
growth rate at present. Researchers around the world have sought ways of enabling
their progress, developing technologies with greater efficiency and lower cost. As
a contribution to the advancement of this technology, this document proposes the
development of a microgrid in continuos current connecting the photovoltaic panels
through a device with tracking strategy developed based on the method perturbation
and observation that will advise the electronic circuit power and a wireless
communication system for monitoring of individual generation. Simulations have
been developed for to choice of connection topology and comparison between the
proposed and traditional control method, assigning different input levels and graphically
checking the output responses. With the design and development of the circuits,
firmware and printed circuit board of the proposed device, it was possible
to carry out experiments to verify its capacity of energy conversion and to verify
responses of control methods mentioned above, placing it as an viable option and
adding a small contribution to technologies of embedded system in the of renewable
energy field.
