Comparative Analysis of Robustness and Tracking Efficiency of Maximum Power Point in Photovoltaic Generators, Using Estimation of the Maximum Power Point Resistance by Irradiance Measurement Processing

“…In the current study, an Isofoton ® ISF-250 PVG mounted at 35° (above the horizontal) was used, so that the irradiance measurement (W/m 2 ) was made with that tendency ( G 35° ). Simulations were carried out using the PVG model of a simple exponential and five parameters [ 1 , 2 , 3 , 16 , 37 ]. In regard to the PVG, its characteristics are summarized in Table 1 .…”

“…It is well known that the MPP is not a static point, but is constantly fluctuating throughout the day, depending on the temperature and irradiance received by the PVG [ 1 , 2 , 3 , 4 ], hence the need to use effective MPPT. Compared to traditional tracking techniques [ 5 , 6 , 7 , 8 ], new ones have been developed, such as model-based techniques [ 9 , 10 , 11 , 12 , 13 , 14 , 15 ], and techniques based on artificial intelligence and bioinspired methods [ 2 , 3 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ]. In general, these techniques seek to read the maximum power point without considering, at least a priori, the possibility that the installation works at a nonglobal maximum.…”

“…There are many proposals in the literature regarding the methods and control algorithms for MPPT, including works that try to classify and compare these methods [ 28 , 29 , 30 , 31 , 32 , 33 ]. However, in practice, the classical algorithm perturb & observe (P&O) [ 3 , 5 , 6 , 7 , 28 ] is the one most used due to its simplicity and easy implementation. Therefore, it is the best pattern with which to compare new proposals [ 28 ].…”

Control inteligente para mejorar el rendimiento de una plataforma semisumergible híbrida con aerogenerador y convertidores de oleaje: sistema de control borroso para la turbina

“…Es interesante observar el desarrollo de controladores de lógica borrosa para sistemas fotovoltaicos (Farfán, Cadena, and Villa 2015;Farhat et al 2015), campo en el que la literatura disponible es mayor que en la eólica y que sigue la misma metodología de búsqueda del MPPT que los controladores en sistemas eólicos. En cuanto al control borroso en la tecnología eólica, en (Simoes, Bose, and Spiegel 1997) se desarrolla y ensaya el control de un aerogenerador de 3.5 kW mediante tres controladores de lógica borrosa, lo que aumenta la complejidad y el tiempo necesario para desarrollar el sistema de control.…”

Comparación entre Rectificador Monofásico con Conmutación Simétrica y Convertidor AC/AC para la Mejora del Factor de Potencia en Microcentrales Hidroeléctricas

“…Como es sobradamente conocido, en la actualidad se ha incrementado el interés por las fuentes de energías renovables (López et al, 2014;Wu et al, 2014;Bordons et al, 2015;García et al, 2016y Real et al, 2017, creándose las llamadas microrredes eléctricas que operan en modo islas, (Naqui et al, 2013;Colak et al, 2015;Farfán et al, 2015;Farhat et al, 2015;Ortega et al, 2016y Piris-Botalla et al, 2016.…”
