Abstract

the  paper  discusses  an  analytical  design  of  dq-based   voltage   positive   feedback   (VPF)   control   for   anti-islanding  of  a  distributed  generation  (DG)  inverter.  Design criteria  for  the  voltage  feedback  gain  are  presented.  Based  on small  signal  stability  and  step  response  analysis,  an  analytical design  method  for  lower  and  upper  bounds  of  the  gain  is described.   It   is   proven   that   conventional   VPF   gain   is significantly  influenced  by  real  power  levels  of  a  DG.  To improve this weakness, a modified VPF is proposed. Simulation study  validates  the  analytical  design  method  and  the  modified VPF  control  performance  for  a  constant  power-  controlled inverters.
