Data-Driven Decentralized Algorithm for Wind Farm Control with Population-Games Assistance

Abstract

In wind farms, the interaction between turbines that operate close by experience some problems in terms of their power generation. Wakes caused by upstream turbines are mainly responsible of these interactions, and the phenomena involved in this case is complex especially when the number of turbines is high. In order to deal with these issues, there is a need to develop control strategies that maximize the energy captured from a wind farm. In this work, an algorithm that uses multiple estimated gradients based on measurements that are classified by using a simple distributed population-games-based algorithm is proposed. The update in the decision variables is computed by making a superposition of the estimated gradients together with the classification of the measurements. In order to maximize the energy captured and maintain the individual power generation, several constraints are considered in the proposed algorithm. Basically, the proposed control scheme reduces the communications needed, which increases the reliability of the wind farm operation. The control scheme is validated in simulation in a benchmark corresponding to the Horns Rev wind farm.

Wind farm control ‐ Part I: A review on control system concepts and structures

“…Faster convergence in comparison to the algorithms proposed in [89,144,145] is reported. In [147,148], a population game approach is used to estimate the multi direction gradient based on stored information. The axial induction factor is optimized.…”

Deep Neural Learning Based Distributed Predictive Control for Offshore Wind Farm Using High-Fidelity LES Data

“…In [4], the optimal coordinated control techniques were used in LES to increase the total wind farm power extraction. In [5], a simple distributed population-games-based algorithm was proposed for wind farm control with multiple estimated gradients being used. In [6], a wind farm controller was proposed to adjust the power generation of individual turbine to match the grid requirements.…”

“…It may be expensive when the energy demand is high. Moreover, the power supplied by the distributed energy generation system is unstable [2,3]. Consequently, the distributed energy storage system is used to store energy when it is available and cheap.…”
