Closure to Discussion on “Primary Frequency Regulation by Deloaded Wind Turbines Using Variable Droop”

摘要

In this paper, a detailed ancillary service pricing mechanism must be in place to encourage wind farm owners to opt for deloaded operating strategies. The authors do not agree that “over-speeding” de-loading tends to respond poorly in the high wind-speed regime; on the contrary, the WTG response to frequency regulation will be better during high wind speeds due to higher reserve generation available. As demonstrated in this work, it is possible to reduce the stability related issues significantly by carefully selecting the deloading percent and the droop parameter of the wind turbine generator.
