“…These issues are common in the everyday practice of wind turbine management at the industrial level but their possible solution involves methods standing at the frontier of the scientific research. Actually, some interesting papers on the subject in the scientific literature are quite recent [18,24]. For these reasons, this work has been organized as a collaboration between academia and industry and the results of this work have been used by the involved company to assess the profitability of some wind turbine retrofitting and to evaluate the possibility of extending it to other wind turbines in the corresponding wind farms.…”

“…In [23] the effects of two types of flow control devices, vortex generators and Gurney flaps, on the power output performance of a 5 MW wind turbine is studied by means of BEM theory. As regards vortex generators and the ex-post study of power production increase through operational data, in [24], an academia-industry joint study is presented and production of two onshore test case wind farms is considered. On one hand, SCADA data with 10 minutes of sampling time are employed; on the other hand, high-frequency power data are employed: the estimates of production improvement are shown to be similar.Summarizing, in this work, three test-cases are presented and discussed:Preprints (www.preprints.org) | NOT PEER-REVIEWED |…”

“…Summing it up, they concluded that, a small sized VGs were enough to delay the separation and keep the flow in control and increasing its magnitude, doesn't necessarily is beneficial. Hwangbo et al [165] presented an academia-industry joint study on the effective methods for the estimation and quantification of the effect of vortex generator installation on wind turbine power production. The study found that the two methods resulted in consistent values.…”

“…The former test case is generated artificially by synthesizing the data according to the logic of pitch angle optimization; the latter test case, instead, is studied through the operational data of a wind turbine. Vortex generator installation is studied also in Reference [28]: The employed methods are the kernel plus of Reference [25] and the so-called power-power approach. The power-power approach is based on the study of the variation (before and after an upgrade) of the power difference between the wind turbine of interest (the target) and a reference wind turbine.…”

“…The power-power approach is based on the study of the variation (before and after an upgrade) of the power difference between the wind turbine of interest (the target) and a reference wind turbine. Its weakness consists of the fact that it needs vast data sets in order to provide meaningful results: The authors of [28] have addressed this problem by employing time-resolved data sets with sampling time of the order of the second, rather than ten minutes, like the typical Supervisory Control And Data Acquisition (SCADA) data. Some proposals to overcome this issue have been formulated in References [21,29]: The idea is that the power-power approach can be generalized by modeling the power of the wind turbine of interest as a function of operation variables of more than one reference near wind turbines.…”
