    Abstract: 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.

    Abstract: A method for feeding a grid by a group of wind turbines (WT1, WT2, WT3, WT4, WT5) in a wind farm and controller (10) and wind farm using the same is provided. The method includes: (a) obtaining first real-time SCADA data and first real-time constant variables concerning each of the wind turbines (WT1, WT2, WT3, WT4, WT5) in the group for a first time point, and first calculating fatigue degree of the wind turbine using the obtained first real-time SCADA data and the first real-time constant variables thereof; and (b) first distributing the grid load among the wind turbines (WT1, WT2, WT3, WT4, WT5) in the group using the calculated fatigue degrees thereof. By having the solutions as mention above, during the operation period of "Crack Generation", it provides output data indicative of a load distribution among the wind turbines (WT1, WT2, WT3, WT4, WT5) of the wind farm in relation to the fatigue degrees of the wind turbines (WT1, WT2, WT3, WT4, WT5). This allows achieving an optimal load distribution among the wind turbines from time to time (i.e. at each execution cycle thereof) always taking into account the fatigue degrees of the wind turbines (WT1, WT2, WT3, WT4, WT5), which represent the operating conditions of the wind turbine prior to occurrence of defect. During "crack generation" operation period of wind turbines, this is helpful for controlling in a mode designed based on fatigue minimization so as to postpone defect occurrence as much as possible which is able to extend lifetime of wind farm with fixed capital cost.

    Abstract: A method for estimating an equivalent impedance of an electrical grid (10) comprises: receiving a plurality of measurement values of a grid voltage V pcc ti and a grid current I pcc ti , measured over a time interval at different time points; minimizing an objective function ( S ) based on the measurement values V pcc ti I pcc ti , a grid voltage parameter ( X̃ 0 ), and parameters ( X̃ 1 ) of the equivalent impedance, which objective function ( S ) comprises a length of an error vector (ε); and determining the equivalent impedance ( X 1 ) by dividing the parameters of the equivalent impedance ( X̃ 1 ) by the grid voltage parameter ( X̃ 0 ). The error vector (ε) is composed of a grid voltage based vector ( VX̃ 0 ) based on grid voltage measurements V pcc ti times the grid voltage parameter ( X̃ 0 ) and a grid current based vector ( A 1 X̃ 1 ) based on grid current measurements I pcc ti times the parameters ( X̃ 1 ) of the equivalent impedance.
