Can wind generation systems contribute to power system auxiliary services?
The project will also fully explore the ability of wind generation systems to participate in power system auxiliary services, focusing particularly on frequency support. Furthermore, the potential of a grid-forming control based on a ‘synchronverter’ applied in the wind generation system to improve the dynamics of the power system will be explored.
Can wind generation systems support grid frequency?
The ability of wind generation systems to support grid frequency is closely related to the synchronization mechanism. The conventional synchronization of wind generation systems with the power grid using PLLs typically involves power injection without offering frequency support.
What are the components of a wind generation system?
In wind generation systems, the wind turbine, the electrical generator and the grid-interfaced converters are three key components that have been developed in the past 30 years 32, 33. The turbine converts wind energy into mechanical energy.
How can a wind generation system be regulated?
One approach involves operating the wind generation system with power reserve, achieved by shifting the MPPT reference. In this approach, the pitch angle can be regulated based on frequency deviations, enabling power reserves to participate in primary frequency control 156.
Does a series-connected wind power system have a high voltage to ground?
In [14, 15], it is suggested that the unit generating the highest power in a series-connected wind power FDC system is subjected to a high voltage to ground, which makes the insulation design of a DC wind power system more difficult, especially in wet offshore environments.
Is a Cuk-based DC/DC converter suitable for small-capacity wind farms?
In , an all-DC series power generation system based on an H-bridge structure is proposed, but it is only suitable for small-capacity wind farms. The authors of propose a new Cuk-based DC/DC converter that has improved efficiency and a lower rated voltage of the coupling capacitor.
