“…The site may increase output at a similar rate as the wind speed again reduces [4]. These rapidly changing [2] events may not just impact the network in local regions, but in cases where a high wind pattern or storm front moves across the UK, could affect several wind farms at different locations.…”

During high wind speed shutdown (HWSS) events, the power outputs of wind power plants may be subject to high ramp rates, causing issues for the System Operator (SO) in predicting total wind output, allocating adequate reserve levels and minimising balancing costs. As the timing of these events is difficult to predict, it is proposed that individual turbines may be used as probabilistic early warning indicators of HWSS events across sites, and by extension to a wide geographical area. The shut-down history of two separate wind farms across Scotland is analysed to determine the likelihood and impact of such events. It is shown that in most cases, HWSS does not result in the full loss of availability. Factors such as turbine elevation and mean wind exposure are key indicators of the order of shut-down across a site. The suggestion that sites could be used as early warning indicators for the pattern of HWSS across a transmission zone is difficult to characterise and for the two wind farms studied, prediction was not consistent

“…The research included in this paper is part of the research and development focused activities within the T ransmission system operation with large penetration of W ind and other renewable E lectricity sources in N etworks by means of innovative T ools and I ntegrated E nergy S olutions (TWENTIES) project financed by the EU (see footnote). This project aims to demonstrate the benefits and impacts of several critical technologies, which are needed to improve the electricity system and thus give Europe the capability of responding to the increasing share of renewables in the energy mix in 2020 and beyond . Within TWENTIES, in the demo#1 called SYSERWIND, the active and reactive power controls of aggregated wind farms are tested in order to verify that wind generators can provide secondary frequency control and voltage/reactive control in the system .…”

Economic assessment of voltage and reactive power control provision by wind farms

The aim of this paper is to quantify the cost of the provision of voltage control by wind power generation. A methodology for evaluating the economic impact of providing different types of voltage control is proposed. This evaluation examines the increase in costs caused by the change in active power losses due to the provision of wind farms voltage control. These losses are computed for different controllers: (a) wind farms are operated at a fixed power factor, (b) wind farms provide proportional voltage control, and (c) wind farms provide reactive power to minimize power losses. Furthermore, these three possibilities are compared with the option of adding flexible alternating current transmission system devices, which are another alternative for supporting the grid by controlling voltage. The methodology outlined is applied to a real and representative Spanish wind harvesting network. Copyright © 2014 John Wiley & Sons, Ltd.

The aim of this paper is to evaluate the influence on power losses of the provision of voltage control by wind farms within the grid that connects them to the transmission network. In addition, the paper estimates the economic profit or cost that this technology could obtain in case of providing voltage control. This paper concentrates on the Spanish situation, where wind farms are connected to the transmission network by an evacuation network without containing loads. Thus, from the economic point of view, just the wind farms owners are affected. The results presented in this paper have been obtained for a real representative Spanish wind evacuation network.
