Demonstration of sustained and useful converter responses during balanced and unbalanced faults in microgrids [PDF]
, 2012 In large power grids where converter penetration is presently low and the network impedance is predominantly reactive, the required response from converters during faults is presently specified by phrases such as “maximum reactive output”.

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.

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

Optimal Power Flow for Unbalanced Bipolar DC Distribution Grids
IEEE Access, 2018 The emergence of distributed energy resources can lead to congestion in distribution grids. DC distribution grids are becoming more relevant as more sources and loads connected to the low voltage grid use dc. Bipolar dc distribution grids with asymmetric loading can experience partial congestion resulting in a nodal price difference between the two ...

A compound control strategy of three‐phase Vienna rectifier under unbalanced grid voltage
IET Power Electronics, 2021 When traditional finite‐set predictive power control is applied to Vienna rectifier, the input current will produce a large number of third harmonics under unbalanced power network, which will seriously affect the normal operation of Vienna rectifier ...
