Advanced Control of Grid-Connected Current Source Converter Under Unbalanced Grid Voltage Conditions

IEEE Transactions on Industrial Electronics, 2018
There are technical challenges when the grid-connected current source converter operates under unbalanced grid voltage conditions. The negative sequence component of the unbalanced grid voltage would result in the low-frequency ripple at dc side, as well as current harmonics at ac side. It has an adverse impact on the system operation.

Coordinated Control Strategy of PMSG and Cascaded H-Bridge STATCOM in Dispersed Wind Farm for Suppressing Unbalanced Grid Voltage

IEEE Transactions on Sustainable Energy, 2021
This article proposes an unbalanced voltage compensation method for a dispersed wind farm (DWF) by cooperating permanent magnetic synchronous generators (PMSGs) with a star-connected cascaded H-bridges (CHB) static synchronous compensator (STATCOM).

Voltage Source Converter Control Under Unbalanced Grid Voltage

2021
The conventional control of the voltage source converter (VSC) assumes that the input voltage is balanced. However, unbalanced voltage is a phenomenon that occurs frequently in actual industrial sites. If the grid voltage is unbalanced, THD increases due to voltage negative component, and low harmonic components appear in DC-link voltage, which ...
