A distributed optimization framework for wind farms

The wind farm has an intrinsically distributed structure, where wind turbines are counted as subsystems of the distributed system. The coupling between the subsystems is the wind flow and the power reference set-points across the turbines, which are designed to provide the total wind farm power demand. Distributed controller design commences with formulating the problem, where a structured matrix approach has been put in practice. Afterwards, an H2 control design formulation is used to find the control signal set points for the wind farm to minimize structural loads on the turbine while providing the desired total wind farm power.
