Title: Multi-objective Wind Farm Control
The increasing amount of electricity production from wind requires the electricity system to expand its capability to accommodate intermittent power generation. Wind energy itself can provide balancing services such as balancing energy and ancillary services using wind farm control. In wind farm control a coordinated control algorithm specifies the operating point of each turbine in order to achieve a certain objective. Besides balancing services, wind farm control can be used to reduce adverse wake effects in wind farms. In wind farms the aerodynamic interaction between wind turbines, i.e. wakes, can result in power losses of up to 30-40% and up to 80% higher fatigue loads. As the global installed wind power capacity increases, mitigation of such wake effects in wind farms is gaining more importance.
Project description
The PhD project therefore investigates wind farm control with regard to the following objectives.
- Maximize the total wind farm power output.
- Follow a reference for the total wind farm power and thereby enable wind farms to provide balancing services to electricity system operators.
- Target one of the prior while reducing the loading on downstream turbines and thereby reduce wind turbine maintenance and extend the wind turbines’ life-time.
- The developed multi-objective wind farm controller is first tested using numerical wind farm simulation tools and later potentially in a real wind farm. A range of low to high fidelity wind farm simulation tools is used in the numerical tests in order to achieve sufficient simulation accuracy for controller development while minimizing computational expenses. The experimental tests aim on validating the performance of the developed wind farm controller.
