Alternatives of Revenue for Corrective Actions of Wind Generators in a Delegated Dispatch

Face to critical contingence situations, the System Operator can require wind farms output reductions. The zonal Delegated Dispatches can act as interface between the System Operator and the producers, allowing a faster and accurate answer. Three probable approaches are mathematically formulated and analyzed in the paper, separately considering the controllability and the possibility of disconnecting the wind farms. The methods are tested and compared by using a realistic test network, extracted from the Spanish national network.
