Output power smoothing of variable speed wind farms using rotor-inertia
Electric Power Systems Research(2014)
摘要
•In this paper, the conventional vector control of the generator is replaced with a fuzzy PID controller.•The optimal power point of the wind turbine is tracked in such a way that the output power is smoothed.•The scheme enables the wind farm to produce a constant power.•In this paper, the rotor-inertia of turbines is used as an energy storage systems.
