Active Power Control of Waked Wind Farms

IFAC-PapersOnLine, 2017
Active power control can be used to balance the total power generated by wind farms with the power consumed on the electricity grid. With the increasing penetration levels of wind energy, there is an increasing need for this ancillary service. In this paper, we show that the tracking of a certain power reference signal provided by the transmission ...

Distribution Strategy of Wind Farm Active Power and Its Implementation

Kongzhi Yu Xinxi Jishu, 2013
Currently, average distribution is generally adopted for the active power control instruction of wind farms. If the wind speed differs much among wind turbines in the wind farm, the output active power of the wind farm may as well differ much from the ...

Integer programming for optimal yaw control of wind farms [PDF]

Wind Energy Science
It is well-known that wakes caused by wind turbines within a wind farm negatively impact the power generation and mechanical load of downstream turbines. This is already partially considered in the farm layout.

Intelligent Fault-Tolerant Active Power Control Using Reinforcement Learning for Offshore Wind Farms

IEEE Access
Given the continuous development of society and the escalating demand for clean energy, there is an imperative focus on wind farm control to overcome the primary obstacle hindering wind farm development: high operation and maintenance costs.

Fast Control-Oriented Dynamic Linear Model of Wind Farm Flow and Operation

Energies, 2018
The aerodynamic interaction between wind turbines grouped in wind farms results in wake-induced power loss and fatigue loads of wind turbines. To mitigate these, wind farm control should be able to account for those interactions, typically using model ...

Power regulation and generator tripping control strategy for direct-drive wind farms under sub/super-synchronous oscillation risk

Diance yu yibiao
Direct-drive wind farms usually trip all wind turbines to ensure power grid security when facing sub/super-synchronous oscillation risks. Tripping the entire wind farm not only seriously damages the production operation of the wind farm, but also causes ...

Model‐free closed‐loop wind farm control using reinforcement learning with recursive least squares

Wind Energy
Wind farms experience significant power losses due to wake interactions between turbines. Research shows that wake steering can alleviate these losses by redirecting the flow through the farm. However, dynamic closed‐loop implementations of wake steering

Data-Driven Approach for Wind Farm Control: Toward an Alternative to FLORIS

IEEE Access
In this paper, we introduce a data-driven approach to wind farm control, offering an alternative to the FLORIS wind farm simulator. Our method estimates the power of a wind farm and determines the optimal yaw angle to maximize power generation. Initially,

Suppression Strategy of Sub/Super-synchronous Oscillations in Doubly-Fed Wind Farm Based on SVG Additional Current Feedback Impedance Reshaping

Zhongguo dianli
Doubly-fed wind farm often interacts with the power grid, leading to sub/super-synchronous oscillations. To address the issue of limited adaptability in suppressing these oscillations using impedance reshaping methods, this paper proposes an impedance ...

Dynamic wind farm controller.

, 2015
This work presents a dynamic wind farm controller for maximising power output of a wind farm. The controller uses a coordinated control approach where the output of the upstream turbines is varied to minimise wake effects on the downstream turbines.
