摘要：

Converters of variable speed wind turbines in a wind power plantmay possess different levels of reactive power capacity under variable power generation of each WT due to wake effects. This letter proposes a variable droop gain control scheme that seeks to mitigate voltage fluctuations at point of common coupling (PCC) by fully utilizing the voltage regulation capability of each WT converter. Droop gain of voltage controller in each WT converter is adaptively adjusted based on its current maximum reactive power capacity so that WT converters at back rows that have higher reactive power capacity can contributemore to PCC voltage regulation.
