Overvoltages in LV rural feeders with high penetration of wind energy

Overvoltage is a major limiting factor for the integration of distributed generation into the grid. This paper, discusses the use of active power curtailment of wind energy systems using pitch angle control and a voltage droop function as means to mitigate the overvoltage problem. This method is validated by a simulation study in PSCAD using typical low voltage rural feeder parameters and 24 hours wind velocity and residential load profiles. Results showed the effectiveness of the method keeping the voltage within acceptable limits.
