The controllers of wind parks that are connected to weak grids can induce unstable oscillations near the fundamental frequency.Such phenomenon can be studied with equivalent impedances of the wind generators,which dep...
The development of DC custom power protection devices is still in infancy that confines the sensitive loads integrated into medium-voltage(MV) and low-voltage(LV) DC networks. Considering the DC doubly-fed induction g...
Sufficient fault ride-through(FRT)of large wind power plants(WPPs)is essential for the operation security of transmission system.The majority of studies on FRT do not include all disturbances originating in the transm...
