Auxiliary systems for wind power generation

Do wind turbines provide ancillary services?

Wind turbines possess the technical ability to provide various ancillary services to the electrical grid. Despite this, renewable generators such as wind and solar have traditionally not been allowed to provide significant amounts of ancillary services, in part due to the variable and uncertain nature of their electricity generation.

Are auxiliary systems compatible with a 120/21 KWE RSOC system?

The results have shown the compatibility of the supply of the auxiliary systems of a 2.3 MW wind turbine with a 120/21 kWe rSOC system in electrolysis/fuel cell mode respectively, with a minimal impact on the annual energy production of the wind turbine.

Can wind turbines provide secondary frequency response?

We focus specifically on providing secondary frequency response (automatic generation control or AGC) and demonstrate that wind turbines have the technical capability to provide this service. The algorithms used are intentionally simple so as to evaluate the capabilities and limitations of the turbine technology.

How often does a wind turbine update pavailable signal?

This value is updated every 4 s and is sent to the turbine's control system. Although the wind turbine used here provides a Pavailable signal that is an estimate of the power in the wind, we observed delays and errors in this signal and so elected to use a measured power curve and wind speed average as described above.

Do wind generators participate in primary tertiary and secondary frequency response regions?

Depending on the type of technology used, wind generators possess the ability to participate in the primary, secondary, and tertiary response regions of Fig. 1. This work focuses specifically on the region of secondary frequency response.

What are ancillary services?

Broadly, ancillary services (or system services) refer to a set of services that complement the primary grid purpose of supplying energy. Examples include system inertia, voltage control, primary frequency control, and operating reserves. Ancillary services may or may not depend on active power.
