hi, sorry to bother you again but your advice is very useful and helpful! I have increased the reactive power at a bus and logged the data into Excel spreadsheet (attached). I was wondering if you could have a look at the voltage collapse curve and comment on the authenticity of it -if it's real

The following comment is not really about Matpower but rather wind farm modelling. A difficulty that can occur when modelling wind farms is that it is common for the wind farm controllers to regulate the power factor at the point of common coupling. Thus if, for example, the wind farm controls

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 dema
