A method of controlling a gas turbine system () may include controlling an inlet guide vane position () to maintain a turbine () exhaust temperature at a corrected value that is a function of a compressor () inlet temperature and a turbine () normalized load. The method may include selecting the minimum value () of a part load tunable value, a part load maximum value and a fixed maximum value of a turbine () exhaust temperature for the corrected value. A corrected value setpoint may be determined () for the gas turbine system () operating at a part load condition where at least one of a fuel flow rate and the inlet guide vane position is controlled () so the corrected value does not exceed the corrected value setpoint. The corrected value may prevent a turbine () engine from exceeding its firing temperature during operation and ensure the engine operates within combustor dynamics and emissions limits.
