Voltage control aspects of wind generation in Meshed distribution grid

In the perspective of coming years the operation of accumulated wind generation in some areas of distribution network in Polish Power Grid will highly influence a voltage pattern. The analysis of necessary reactive power sources to keep voltage in permissible ranges and of an impact on grid losses was carried out. The cases of different wind farm reactive power operation modes were studied as well as usage of additional reactive power sources to maintain voltage in permissible ranges. Studies were carried out for various wind generation levels expected in the next few years.
