Power control strategies during voltage sags according to Spanish grid code [PDF]
, 2018 In order to connect any power converters into the grid there are some grid requirements to insure the safe operation of the grid. So, the control of the converters especially during abnormal condition e.g. during voltage sags is

Grid-tied converter operated under unbalanced and distorted grid voltage conditions
Bulletin of the Polish Academy of Sciences Technical Sciences, 2020 The paper presents a three-phase grid-tied converter operated under unbalanced and distorted grid voltage conditions, using a multi-oscillatory current controller to provide high quality phase currents. The aim of this study is to introduce a systematic design of the current control loop.

Harmonic Analysis of Type-3 Wind Turbines Subject to Grid Unbalance
IEEE Open Access Journal of Power and Energy, 2023 The objective of this paper is to adequately model a doubly-fed induction generator (DFIG)-based type-3 wind turbine under grid unbalance by considering not only positive and negative-sequence circuits but also the 3rd harmonic circuit. This 3rd harmonic
