1. A method for controlling a power generating system, the power generating system comprising at least one power generating subsystem connected to a point of interconnection (POI), the method comprising:
receiving at a subsystem controller of the power generating subsystem, a first data signal corresponding to a feedback signal of an electrical parameter regulated at the POI, the feedback signal having a first signal fidelity;
receiving at the subsystem controller, a second data signal indicative of the electrical parameter generated at the power generating subsystem, the second data signal having a second signal fidelity that is higher than the first signal fidelity;
with the subsystem controller, generating a correlation value between the first and second data signals by filtering a value difference between the first and second data signals and applying the correlation value to a setpoint value for the electrical parameter regulated at the POI to generate a modified setpoint value; and
with the subsystem controller, using the modified setpoint value and the second data signal to generate a setpoint command for the power generating subsystem and controlling generation of power at the power generating subsystem using the setpoint command to regulate the electrical parameter at the POI.
