System and method for farm-level control of transient power boost during frequency events

Abstract:

A method for controlling a wind farm connected to an electrical grid includes receiving, via a farm-level controller, a frequency signal from the electrical grid. If the frequency signal is indicative of a frequency event occurring in the electrical grid, the method includes implementing, via the farm-level controller, a control scheme for providing frequency regulation and power-swing stabilization for the electrical grid. For example, the control scheme includes receiving, via the farm-level controller, individual output boost capabilities from each of the plurality of wind turbine generators, calculating, via the farm-level controller, a power command based on the individual output boost capabilities and based on one or more grid code requirements of the electrical grid, distributing, via the farm-level controller, the power command to each of the wind turbine generators.
