Wind farm control for wake-loss compensation, thrust balancing and load-limiting of turbines

As renewable energy sources such as wind farms become dominant, new challenges emerge for operating and controlling them. Traditionally, wind farm control aims to dispatch power set-points to individual turbines to maximize energy extraction and, thus, their usage as assets. Yet, grid balance and frequency support are fundamental in presence...

Towards Active Power Control of Waked Wind Farms: A study in SOWFA simulation environment

The power generated from wind is not synchronized to the electrical frequency of the power grid. Grid balancing services must be assured when the output from a wind farm is integrated into the electrical grid to avoid the risk of blackouts.<b> Active Power Control (APC)</b> methods are employed to provide grid balancing ancillary services such...

A constrained wind farm controller providing secondary frequency regulation: An LES study

Active power control for wind farms is needed to provide ancillary services. One of these services is to track a power reference signal with a wind farm by dynamically de- and uprating the turbines. In this paper we present a closed-loop wind farm controller that evaluates 1) thrust coefficients on a seconds-scale that provide power tracking...
