Diseño y control de los convertidores CC/CC para un sistema híbrido de generación eléctrica compuesto por paneles fotovoltaicos, aerogenerador y pila de combustible con electrolizador

Résumé

In order to interconnect the power sources it is necessary to use power converters, that have been improved in the last years thanks to the advancement of power electronics and also to the faster and more accurate control systems. All that allows providing a constant voltage to the load regardless of fluctuations of renewable energy source from which the energy is obtained. The hybrid generation system whose DC/DC converters has been designed in this thesis consists of photovoltaic system (solar panels), wind energy system (wind turbine), system of hydrogen (fuel cell and electrolyzer)and auxiliary energy storage system (battery and / or ultracapacitor) in order to maximize energy production, meeting energy demand, reduce outputfluctuations and optimize production.
