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 ...

Control of Grid Connected Converters Under Unbalanced Grid Faults

2018 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2018
A grid connected inverter with an unbalanced voltage at the point of common coupling creates oscillation in DC link voltage at twice the grid frequency and inject highly distorted current into the grid. In this paper analytical expression for oscillation of DC link voltage and distortion in current injected to the grid are derived.

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 ...
