Wind power generation voltage stabilization system

Do wind turbines support grid voltage during voltage deviations?

In a power system with a high penetration of wind power generation, it is required that the wind turbines support the grid voltage during voltage deviations to ensure the system's security. After a voltage drop, the system's P – U curve is shown in Figure 2.

How to ensure the voltage stability of a wind turbine?

To ensure the system's voltage stability, there are certain requirements for the short-circuit capacity, STP at the grid connection point in the fault test experiments. According to industry standards , its value should be greater than three times the rated capacity, SWTN of the wind turbine.

Do wind turbines with grid-forming control support voltage stability?

Additionally, the MSR values during the recovery period after fault clearance also show an upward trend. Therefore, wind turbines with grid-forming control effectively support voltage stability and mitigate the risk of voltage instability associated with high wind power penetration.

Can new energy sources improve the voltage stability of grid-forming wind power systems?

The aforementioned research findings are useful for enhancing the voltage stability of power grids with new energy sources, but the transient voltage response of grid-forming wind power systems and parameter ranges lack a theoretical design basis.
