      When facing real systems PI tuning, the plant is modeled disregarding its physical limitations. Consequently, the PI output may increase indefinitely its value; phenomenon called Windup. This paper presents a review and a ...

    • SVC model for voltage control of a microgrid 

      Bogónez Franco, Francisco; Balcells Sendra, Josep; Junyent, Oriol; Jordà, Josep (2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Low power renewable sources, connected to low voltage micro-grids, are becoming more and more common. Since there is a high degree of uncertainty on the availability of such sources, this causes problems of stability and ...
