Simulink Based Model of PV Plant

Abstract

The   paper   proposes   the   Simulink   based   model   of   a   grid-connected PV plant. The model considers standard monocrystalline  PV  modules,  even  if  any  typology  of  sylicon based PV module can be used, because the values of the technical specifications  can  be  easily  modfied  by  the  user  by  means  of masks.  The  proposed  model  considers  a  multi-inverter  PV  plant with   local   MPPT,   implementing   the   Perturbe   and   Observe strategy.  Moreover,  also  the  models  of  the  interface  protection device,  of  the  coupling  capacitor  and  of  the  L-filter  have  been implemented,   allowing   to   modify   the   characteristic   values. Several  simulation  results  are  presented  in  this  paper  and  they agree with the expected values.
