Circulation wind power generation system

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 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).

How do wind generators contribute to grid stability?

Hence, wind generators are required to contribute to grid stability through active power and frequency control to help to maintain the power balance in power systems 52. Grid codes specify the permitted range of voltage and frequency variations that wind generators must adhere to during grid connection.

How has technology changed wind power generators?

Meanwhile, the rapid development of power electronics technology has enabled a technological transformation in wind power generators over the past three decades (for example, from fixed-speed low-power wind turbine generators to variable-speed high-power wind turbine generators) 17, 19, 29.
