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). A first data signal is obtained corresponding to a feedback signal of an electrical parameter regulated at the POI, the first data signal having a first signal fidelity. A second data signal indicative of the electrical parameter generated at the power generating subsystem is obtained, the second data signal having a second signal fidelity that is higher than the first signal fidelity. A correlation value between the first and second data signals is obtained by filtering a value difference between the first and second data signals. The correlation value is applied to a setpoint value for the electrical parameter regulated at the POI. The modified setpoint value and the second data signal are combined to generate a setpoint command for the power generating subsystem that is used for controlling generation of power at the power generating subsystem to regulate the electrical parameter at the POI.
