System and method for controlling a power generating system

A system for controlling a power generating subsystem that is connected to a power generating system at a point of interconnection (POI), comprising:

• a subsystem controller configured with the power generating subsystem, the subsystem controller comprising at least one processor configured to perform a plurality of operations, the plurality of operations comprising:
• receive a first data signal corresponding to a feedback signal of an electrical parameter contributed by the power generating subsystem to the POI, the electrical parameter measured remote from the power generating subsystem prior to integration with electrical parameters from other power generating subsystems at the POI, the electrical parameter being one of power factor or reactive power and the first data signal having a first signal fidelity;
• receive a second data signal indicative of the electrical parameter generated at the power generating subsystem, the second data signal measured at the power generating subsystem and having a second signal fidelity that is higher than the first signal fidelity;
• generate a correlation value between the first and second data signals by filtering a value difference between the first and second data signals;
• generate a modified setpoint value by applying the correlation value to a setpoint value for the electrical parameter regulated at the POI;
• use the modified setpoint value to generate a setpoint command for the power generating subsystem;
• and
• control power generation at the power generating subsystem using the setpoint command to achieve the setpoint value for the electrical parameter at the POI.
