Hi, I have modelled wind farms in MATPOWER, and as Ray has suggested below, did use negative values for the active power injection of the wind farm (i.e. subtracted this from existing load at that bus), but a positive value of reactive power consumption (i.e. added this to the existing load Q demand at that bus) assuming that the wind farm comprises asynchronous wind turbine generators. Shunt reactances or susceptances can be entered as positive values in columns 5 and 6.
