TY  - JOUR
AB  - This paper presents a uniform optimal power sharing strategy to coordinate the wind turbines (WTs) in a wind farm (WF)to provide occasional and continuous frequency response (FR). The coordination of WTs is formulated as an optimisation problemthat takes into account the WT dynamics and tries to reduce the long term loss of energy yield caused by the provision of FR. Thisis achieved by maximising the total kinetic energy of the WF over time while reducing wear and tear of WTs. The proposed optimalpower sharing strategy relies on periodic communication between each WT and a WF controller. Local linear approximations areemployed to predict the system behaviour and the solution of the optimisation problem is obtained using the proposed centralisedand/or distributed algorithm. The distributed algorithm only requires one-way communication between the WF controller and localWTs, reducing the communication overheads. Simulation studies are carried out on a WF model to demonstrate the effectivenessof the proposed strategy. The results show the strategy enables reduction of yield loss over previous methods while avoiding overtorque operation during FR provision.
