Wind power generation centralized power system

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.

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.

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.

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).

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.

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 years32,33. The turbine converts wind energy into mechanical energy.
