Abstract: A multi-farm wind power dispatch management system is provided which includes wind turbine dispatch controllers for controlling wind power dispatch of respective wind farm components and wind farm dispatch management systems for receiving respective wind farm component operating parameters and generating respective farm-level operating parameters. The system also includes group dispatch management systems for receiving the farm-level operating parameters and generating respective group level operating parameters. The system also includes a master dispatch management system for receiving the group-level operating parameters; computing a real time output power generated by the wind farm components; determining a difference between the real time output power and a committed output power; and generating reference commands, based on the difference, for controlling at least one of, the wind farm component operating parameters, the farm-level operating parameters, the group level operating parameters, or combinations thereof to reduce the difference and dispatch the committed output power.

Abstract: A method for controlling a wind farm including a plurality of wind turbines is provided. The method includes computing an error between a farm-level base point power and a measured wind farm power, generating an aggregated farm-level active power set point for the wind farm based on the error and a frequency response set point, generating aggregated turbine-level active power set points based on the aggregated farm-level active power set point, transmitting the aggregated turbine-level active power set points, determining aero power set points and storage power set points for the respective wind turbines and energy storage elements of the respective wind turbines from the aggregated turbine-level active power set points, and controlling the plurality of wind turbines for delivering aero power based on the respective aero power set points and controlling the energy storage elements to provide storage power based on the respective storage power set points.

Abstract: A system for automatic generation control in a wind farm is provided. The system includes a wind farm controller for controlling the plurality of energy storage elements. The wind farm controller receives an automatic generation control set point from an independent system operator, generates a farm-level storage power set point for the wind farm based on the automatic generation control set point, generates individual storage power set points for the plurality of energy storage elements based on states of charge of the respective energy storage elements, and controls the plurality of energy storage elements based on the individual storage power set points for dispatching storage power to perform automatic generation control.
