Gains obtained in hybrid systems of energy generation solar photovoltaic and wind power for rural electrification with the use of fuzzy logic controllers based

This paper presents the gains from the application of fuzzy logic control in a hybrid power generation wind-photovoltaic for small rural. The use of alternative and renewable energy has been increasingly discussed in all sectors of society. The interest in these sources of energy, alternative and renewable, is of fundamental importance, both in terms of the shortage, as the price of oil, and the environmental issues involved in the use of renewables. The variability in the intensity of wind and solar energy can be circumvented by complementation between a source and one or more stability set by the generation system. When using a fuzzy control system, is expected to reach the point of maximum power generation, transferring substantially all the energy generated to load and / or batteries when their use is not immediate. The operation of the fuzzy controller was simulated using the MATLAB® software, through the Fuzzy Logical Toolbox. It was found through simulations that this model can be used efficiently in hybrid power generation, providing better utilization of alternative energy sources.Ovaj rad prezentuje dobitke dobnijene korišćenjem kontrolera neprecizne logike u hibridnim sistemima za proizvodnju struje iz solarne energije i energije vetra za male poljoprivredne objekte. Korišćenje alternativnih i obnovljivih izvora energije se sve više primenjuje u svim oblastima društva. Razumevanje alternativnih i obnovljivih izvora energije je od fundamentalnog značaja, kako u pogledu ograničenja kao što je cena nafte, tako i u pogledu uticaja na životnu sredinu. Variranje u intenzitetu vetra i solarnoj energiji se može izbeći putem dopunjavanja između izvora i jednog ili više stabilnih uređaja podešenih od strane generatora. Kad se koristi kontroler neprecizne logike očekivano je da sistem postigne tačku maksimalne proizvodnje struje i da postepeno prebaci svu proizvedenu energiju ili potrošačima ili baterijama tokom perioda niske potrošnje. Rad kontrolera neprecizne logike je simuliran korišćenjem programa MATLAB® kroz Fuzzy Logical Toolbox. Kroz simulaciju je utvrđeno da se ovaj model može uspešno koristiti u hibridnoj proizvodnji struje kao i da pruža mogućnost za bolje korišćenje alternativnih izvora energije
