Power quality in a distribution network after wind power plant connection

Power quality in a distribution network is seen in this paper as a limiting factor of wind power plant (WPP) connection. Based on computation of short-circuit capacity, the power quality is estimated with respect to flicker emissions and relative voltage changes caused by the WPP operation. Potential electrical energy production of a real WPP installation site is related to the power quality problem in surrounding distribution network. Recognized discrepancy pointed out to a necessity of network reinforcement aimed for improved short circuit capacity should this installation site be made viable for full utilization.
