Abstract: A system and method are provided for controlling a power generating system having at least one power generating subsystem connected to a point of interconnection (POI). Accordingly, the subsystem controller of the power generating subsystem obtains a first data signal indicative of an electrical parameter at the POI and a second data signal indicative of the electrical parameter at the generating subsystem.

The subsystem controller generates a setpoint command for the power generating subsystem based, at least in part, on the first modeled value for the electrical parameter.
