文摘
- •
The effect of DFIG operational limits on long-term voltage stability is analyzed.
- •
The use of fixed limits during simulations is adequate when wind speed is constant.
- •
Under ramp up wind speed, DFIG limits should be considered variable in simulations.
- •
Under ramp down wind speed, the use of fixed limits decreases voltage stability margin.
