Take this simple case with 3 buses and 2 transmission lines (10 kV
system). It comprises one conventional generator (bus1), a wind farm
generating 20 MW (bus3) and one load S=40+j20 MVA (bus2).
For dispatchable generators (like bus1), just define "type" = 2 (PV)
and fill the generator data for that generator. For non-dispatchable
generation (such as wind power), just set bus "type" to 1 (PQ) and
define the power injected as negative load.
Two transmission lines connect the generator and the wind farm to bus
2, thus feeding the load. Pd = -20 MW for bus 3 means that the wind
farm is generating 20 MW. Also, if the wind farm is comprised of
induction wind turbines, you can model any reactive power consumprtion
by defining "Qd" as a positive quantity.
