360 degree wind power generation system

What are the different types of wind turbine generation systems?

Two typical configurations of power electronic converter-based wind turbine generation systems have been widely adopted in modern wind power applications: type 3 wind generation systems with doubly fed induction generators (DFIGs) (Fig. 2a); and type 4 wind generation systems with permanent magnet synchronous generators (PMSGs) (Fig. 2b).

What are the requirements for a wind generation system?

These requirements are twofold: first, wind generation systems must operate effectively under diverse grid conditions and disturbances arising from interactions between wind generation systems and the grid; and second, wind generation systems are mandated to provide various auxiliary services to ensure the optimal operation of the power systems.

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.

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.

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.

Should converter-interfaced wind power generators be regulated?

Expanding the role of converter-interfaced wind power generators in future power systems from passively following the power system to actively participating in its regulation offers frequency support functionality, which is beneficial for enhancing the frequency stability of power systems with high penetration of wind and low inertia.
