Abstract: Assessing performance impact of a power upgrade of one or more wind turbines of a wind farm that includes a group of target wind turbines and a group of reference wind turbines. For each of the target wind turbines, a transfer function is generated, establishing a relationship between the locally measured wind speed at the target wind turbine and locally measured wind speeds at each of the reference wind turbines. A power upgrade is performed on each of the target wind turbines, and subsequently power performance data is obtained for the reference wind turbines and the target wind turbines, within one or more wind speed intervals. For the target wind turbines, the wind speed intervals are based on estimated wind speeds, based on locally measured wind speeds at the reference wind turbines and the transfer functions.
