Provision of Ancillary Services with Variable Speed Wind Turbines [PDF]

, 2014
In recent years, the amount of wind turbines in the power system has increased tremendously. As the current wind turbines do not participate in the provision of ancillary services such as frequency control and voltage control, this may compromise the ...

Grid Voltage Unbalance and The Integration of DFIG’s

, 2013
Double-fed induction generators (DFIG’s) became the predominant generator installed for wind generation applications in the mid 1990’s. Issues pertaining to the operation and control of DFIG’s subsequently became apparent, particularly in weak areas of the grid network.

Control of DFIG on Variable Wind Speed

International Journal of Thermal and Environmental Engineering, 2015
Doubly Fed Induction Generator (DFIG) is one of the most reliable wind generator. Major problem in wind power generation is to generate constant frequency output on variable speed. This paper summarizes & reviews major techniques used in DFIG, and investigate various technologies developed by and solution proposed by different researchers to ...

A novel hybrid interlinking transformer-integrated DFIG wind power and energy storage system with flexible control strategy

International Journal of Electrical Power & Energy Systems
Double-fed induction generator (DFIG) based wind turbine generator (WTG) demonstrates pronounced sensitivity to the abnormal grid voltages, such as sag, swell or harmonic, which can precipitate disconnections from the power grid due to fault ride-through

Overview of HVRT technical measures for DFIG

IOP Conference Series: Earth and Environmental Science, 2017
A With the rapid increase of the proportion of double-fed induction wind turbines generator (DFIG), higher requirements are proposed for the continuous operation ability under external power grid failure. The paper first analysed the transient process of DFIG in cases of power grid voltage surge, proposed the related standard requirements for high ...
