Methods and systems for heavy fuel oil in gas turbines

A method, comprising:

• receiving a plurality of signals from sensors disposed in a gas turbine system, wherein the gas turbine system comprises a compressor section fluidly coupled to a gas turbine section;
• deriving a vanadium content in a gas turbine engine fuel based on at least one of the plurality of signals;
• determining if a control curve should be adjusted based on the vanadium content in the gas turbine engine fuel;
• and
• if it is determined that the control curve should be adjusted, then deriving an adjustment to the control curve based on the vanadium content, and applying the adjustment to the control curve to derive an adjusted control curve, wherein the control curve is plotted against a compressor pressure ratio (CPR) ordinate axis and an exhaust temperature abscissa axis.

A non-transitory computer-readable medium having computer executable code stored thereon, the computer executable code comprising instructions to:
