面向并网逆变器的频率自适应选择性谐波控制

In this paper, a frequency adaptive selective harmonic control (FA-SHC) scheme is proposed. The FA-SHC method is developed from a hybrid SHC scheme based on the internal model principle, which can be designed for grid-connected inverters to optimally mitigate feed-in current harmonics. The hybrid SHC scheme consists of multiple parallel recursive ($nk\pm m$)-order ( $k$ = 0, 1, 2, $\ldots$, and $...
