Wind Farm Control Survey

This document is a delivery in the project NORCOWE. It is part of
work package WP3.2.2. The main goal is to establish the present
state-of-the-art for wind farm control for both research and practice.
The main approach will be to study the literature. This will of cause
be much more efficient for the research part than for the practice
part. It is however not the intention to do company interviews or
similar.

This report is structured into a section for each WF control
objective. These sections then includes the important control
project issues: choice of input and output, control method, and
modelling used for controller design and simulation respectively.
A short section then discusses published literature from
industry. Finally a conclusion is given discussing established
results, open challenges and necessary research. An appendix
present a method for optimising the energy in a one row wind
turbine farm based on a dynamic programming type of method.
