Technical FAQs 4

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.

Can energy storage control wind power & energy storage?

As of recently, there is not much research done on how to configure energy storage capacity and control wind power and energy storage to help with frequency regulation. Energy storage, like wind turbines, has the potential to regulate system frequency via extra differential droop control.

Why do wind power and photovoltaics lack voltage support capability?

Wind power and photovoltaics in new energy power systems lack voltage support capability. As the proportion of synchronous generators (SG) decreases, the system's short-circuit capacity also decreases, leading to insufficient short-circuit ratio (SCR).
