Can large-scale wind power plants be integrated into modern power systems?
However, the traditional power system generation units are centralized located synchronous generators with different characteristics compared with wind turbines. This paper presents an overview of the issues about integrating large-scale wind power plants into modern power systems.
What is a centralized generated system?
centralized generated system has a central location of power being generated before the generated power is transmitted, distributed and therefore made available to consumers. Clearly, power generated at the central station cannot be same as the total sum of power supplied to consumers.
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.
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 is the control system for wind turbines?
The proposed control system is based on a complex hierarchical control architecture. A central supervisory control level decides the active and reactive power references for each wind turbine local control level, based on received production orders (maximum production or power regulation) from the system operator.
What are the advantages of centralized generators?
Finally, the distributed generators can compensate locally the power missing from a fault that happened to a single generator, reducing the numbers of users that could be affected by that failure. The centralized generation is the classic standard power management model for the very big power plants connected to the power system.
