    • Control strategies to smooth short-term power fluctuations in large photovoltaic plants using battery storage systems 

      Marcos Álvarez, Javier Upna; Parra Laita, Íñigo de la Upna; García Solano, Miguel Upna; Marroyo Palomo, Luis Upna (MDPI, 2014)   Artículo / Artikulua  OpenAccess
      The variations in irradiance produced by changes in cloud cover can cause rapid fluctuations in the power generated by large photovoltaic (PV) plants. As the PV power share in the grid increases, such fluctuations may ...
    • Grid integration of large-scale PV plants 

      Parra Laita, Íñigo de la Upna (2015)   Tesis doctoral / Doktoretza tesia  OpenAccess
      Over the last few years, the considerable increase in the number of multi-MW PV plants has led transmission system operators (TSO) to express concern over potential PV power fluctuations caused by transient clouds. As a ...
    • On the on-site measurement of the degradation rate of crystalline silicon PV modules at plant level 

      Pascual Miqueleiz, Julio María Upna; Berrueta Irigoyen, Alberto Upna; Marcos Álvarez, Javier Upna; García Solano, Miguel Upna; Marroyo Palomo, Luis Upna (IEEE, 2018)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      This paper proposes a method for measuring the degradation rate of crystalline silicon PV modules at plant level in two different ways as a form of verification. As actual levels of degradation rate have been observed to ...
    • Procedimientos avanzados para el análisis del comportamiento de grandes centrales FV 

      Muñoz Escribano, Mikel Upna (2018)   Tesis doctoral / Doktoretza tesia  OpenAccess
      La energía fotovoltaica (FV) ha experimentado un gran crecimiento en los últimos años y se prevé que lo siga haciendo en los próximos. La razón principal es el descenso espectacular que ha experimentado su precio. A pesar ...
