Zusammenfassung:	A method for wind power curtailment optimization comprises calculating the power flow for a power network for the day-ahead; calculating a contingency analysis for the power network for the day-ahead, comprising forecasted power generation, power consumption and topology of said power network, together with a set of contingency scenarios; calculating a sensitivity factor of a power flow for each power network branch to a power injection by each wind power plant, wherein the sensitivity factor is calculated only for the periods of time of the day-ahead for which overloaded branches have been detected during the solving of the power flow or during the solving of the contingency analysis; selecting a subset of the wind power plants having at least one sensitivity factor above a predetermined threshold as curtailment candidates; and calculating the wind power curtailment restricted to the selected subset of wind power plants.
