System and method for automatic generation control in wind farms
First Claim
1. A method for automatic generation control in a wind farm comprising:
- receiving an automatic generation control set point from an independent system operator;
generating a farm-level storage power set point for the wind farm based on the automatic generation control set point using a wind farm controller;
generating individual storage power set points for a plurality of energy storage elements using the wind farm controller, wherein each of the plurality of energy storage elements is coupled to a corresponding wind turbine of a plurality of wind turbines, and wherein the individual storage power set points are generated based on states of charge of respective energy storage elements; and
controlling the plurality of energy storage elements based on the individual storage power set points for dispatching storage power to perform automatic generation control based on an aggressive optimal dispatch method, wherein dispatching the storage power based on the aggressive optimal dispatch method comprises prioritizing a storage power dispatch from the plurality of energy storage elements based on charging coefficients and discharging coefficients in a descending order, wherein the charging coefficients are represented as;
