Optimal controllability of wind generators in a delegated dispatch

A delegated dispatch is a control centre that transmits the requirements of the system operator in critical situations to distributed generation resources, by monitoring and controlling the wind generation producers in a region. When the system needs corrective actions, the system operator sends these requirements to the delegated dispatches. Each delegated dispatch is responsible for matching the goals specified by the system operator, specifying commands and settings to the involved wind generators. In the present paper, some functions of a delegated dispatch are analysed, when applied to a real network. An optimization method is proposed, aiming to reach the regional constraints imposed by the system operator. In the formulation, variations in the output restriction for wind provision, different wind turbines technologies and active and reactive controllability actions are considered.
