Wind farm inertial response
The present invention is concerned with an operation of a wind farm with a plurality of wind turbines in view of a dynamic frequency response. According to the invention, dynamic frequency support and power production for all wind turbines in a wind farm are handled concurrently in a single optimization step and taking into account wake effects within the wind farm as well as optional wind forecast information. The dynamic frequency support capability of the entire wind farm is planned in advance according to grid requirements and power system condition changes. While existing methods de-load wind turbines with a static percentage in order to supply additional power when needed, the proposed method incorporates the dynamic frequency support into the optimal operation system of wind farm.
Method for operating a wind turbine generator
A method for modifying the power output of a wind turbine generator. The power output of a wind turbine generator can be modified based on the rate of fatigue and/or damage calculated for components within the wind turbine generator. Damage and/or fatigue can be calculated based on current or predicted future operating conditions. The turbine operation can be modified if the cost of damage and/or cost of fatigue is less than a value for the electricity produced. In this case, the rate of fatigue is calculated using models of the wind turbine generator or its components, where the model may be based on a metamodel or by an Equivalent Operating Hours approach.
