1. A method for automated control of a combustion turbine fuel composition through automated modification of a ratio of fuel gas, comprising:
- providing a first fuel source;
providing a second fuel source;
supplying fuel to a combustion turbine in a blend of fuel from the first source and second source;
specifying one or more first tuning priorities, wherein the first tuning priorities comprise one or more selected from the group comprising NOx levels, power level and combustion dynamics, wherein specifying the NOx levels or combustion dynamics tuning priority comprises adjusting the tuning priority within a range and specifying the power level tuning priority comprises switching on or switching off the tuning priority, and wherein the specifying of the one or more first tuning priorities operates to change a first set of stored operational standards;
specifying one or more second tuning priorities, wherein the specifying of the one or more second tuning priorities operates to overlay a second set of stored operational standards upon the first set of stored operational standards, wherein the specifying of the one or more second tuning priorities comprises switching on or switching off the second tuning priority;
sensing in real-time or near real operational parameters of the gas turbine;
determining whether the operational parameters are within the first or second set of stored operational standards;
adjusting the blend of the first fuel source and the second fuel source, based on whether the operational parameters are within the second set of stored operational standards.

Abstract
Provided herein is a method for automated control of the gas turbine fuel composition through automated modification of the ratio of fuel gas from multiple sources. The method includes providing first and second fuel sources. The method further includes sensing the operational parameters of a turbine and determining whether the operational parameters are within preset operational limits. The method also adjusting the ration of the first fuel source to the second fuel source, based on whether the operational parameters are within the preset operational limits.
