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.

Operation of Grid-Connected DFIG Under Unbalanced Grid Voltage Condition

IEEE Transactions on Energy Conversion, 2009
Doubly fed induction generator (DFIG) still shares a large part in today's wind power market. It provides the benefits of variable speed operation cost-effectively, and can control its active and reactive power independently. Crowbar protection is often adopted to protect the rotor-side voltage source converter (VSC) from transient overcurrent during ...

Study on grid feed forward strategy under Unbalanced Grid Condition

2019 14th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2019
In the case of unbalanced power grid, the disturbance of the power grid is introduced into the feed forward accurately, thus, the output feed-forward part of the inverter is in perfect agreement with the unbalanced power grid, in order to achieve good and effective control of the current of the converter in the dynamic change of the power grid.

Flexible Operation of Grid-Interactive Converters under Unbalanced Grid Conditions

Advanced Science and Technology Letters, 2015
The grid codes of power systems with high penetration of renewable sources impose stringent requirements on the operation of Distributed Renewable Energy Sources (DRES) under the unbalanced grid faults. A generalized power control strategy based on the symmetrical components is used in this paper to control the power delivery under unbalanced grid ...

Impact of unbalanced grid conditions on PV systems

IEEE PES General Meeting, 2010
With more and more photovoltaic (PV) panels, energy storage devices and other small generators being put into service, it is necessary to integrate them into power systems. Grid integration provides a reliable means for customers to use renewable energy such as solar at its maximum and to use other sources as backup.
