“…When the WTs are employed to provide extra reactive power to support the voltage control, the lifetime of WT's power converter could be reduced due to its additional current stress in each power module, which is an important challenge for modern WF lifetime requirement [10]. With the implemented MPPT method, due to the wake effect, upstream WT has more active power generation than downstream WT at the wind directions that the WF has wake loss [15], which results in shorter lifetime of upstream WT. Consequently, by using dispatching appropriate reactive power, (i.e.…”

“…Many works have focused on the development of wake model [11] and [12]. With the consideration of the wake effect, WF layout optimization methods [13] and [14] and the active power control methods [15] and [16] have been developed for the power loss reduction. Because of the wake effect, downstream WT's available active power depends on the upstream WT's active power control method.…”

“…The active power curve incorporates 5 control regions, where the MPPT is implemented in region 3. The active power of each WT is estimated by the Katic model [28] and [15]. The WF is assumed to be an offshore WF and the decay constant k=0.04 is adopted [29].…”

“…This approximation is mainly due to the high nonconvexity of the wake model that makes the problem hard to be treated directly under a control perspective. The available approaches mainly deal with either model-free decentralized methods, as in [2], [3], philippe.loevenbruck@edf.fr or model-based ones as in [4], and [1]. The aforementioned optimization algorithms rely on the existence of local control strategies for individual WTs that can stabilize around the obtained optimal set points [2].…”

Abstract-In this paper we address the problem of power sharing among the wind turbines (WTs) belonging to a wind farm. The objective is to maximize the power extraction under the wake effect, and in the presence of wind disturbances. Because of the latter, WTs may fail in respecting the optimal power sharing gains. These are restored by employing a consensus control among the WTs. In particular, under the assumption of discrete-time communication among the WTs, we propose a distributed PID-like consensus approach that enhances the rejection of the wind disturbances by providing the power references to the local WT controllers. The latter are designed by employing a novel feedback linearization control that, acting simultaneously on the WT rotor speed and the pitch angle, guarantees the tracking of general deloaded power references. The obtained results are validated on a 6-WT wind farm example.

Summary The progression of wind turbine technology has led to wind turbines being incredibly optimized machines often approaching their theoretical maximum production capabilities. When placed together in arrays to make wind farms, however, they are subject to wake interference that greatly reduces downstream turbines' power production, increases structural loading and maintenance, reduces their lifetimes, and ultimately increases the levelized cost of energy. Development of techniques to manage wakes and operate larger and larger arrays of turbines more efficiently is now a crucial field of research. Herein, four wake management techniques in various states of development are reviewed. These include axial induction control, wake steering, the latter two combined, and active wake control. Each of these is reviewed in terms of its control strategies and use for power maximization, load reduction, and ancillary services. By evaluating existing research, several directions for future research are suggested.
