Large, moderately rapid voltage fluctuations due to a PV farm: an additional limit on how much PV fits in the medium-voltage grid
A solar (PV) farm (approx. 60 MW) is connected at 21 kV level to a 110/21 kV substation via a 24 km long cable. Power fluctuations of the PV farm caused stationary voltage limit violations in the medium-voltage (MV) grid.
