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.
Do wind generators provide ancillary services?
Often, provisions are laid down in grid codes or connection agreements, but wind generators are rarely called upon to provide ancillary or system services. An example of public information of this nature is Hydro-Quebec's comparison of fast-frequency response from two wind turbine technologies ( Asmine et al. , 2017).
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 control actions in a wind turbine?
From a control engineering perspective, various control actions can be identified in a WT. One important control action involves adjusting the pitch angle to stabilize the power output when the wind speed exceeds the rated wind speed. This is achieved by altering the pitch angle, which changes the blade surface exposed to the wind .
Do wind turbines support a frequency drop mitigation-modified operation?
According to the research papers by Attya and Hartkopf, wind turbines support frequency drop mitigation-modified operation. (Attya AB, Hartkopf T. Wind turbine contribution in frequency drop mitigation-modified operation and estimating released supportive energy. IET Generation, Transmission & Distribution. 2014; 8 (5):862-872; Attya AB, Hartkopf T. Wind turbines support techniques during frequency drops—Energy utilization comparison. AIMS Energy. 2014; 2 (3):260-275)
