Embodiments of the disclosure provide a method for operating a combined cycle power plant (CCPP). The method may include creating a variant control profile for the CCPP for a power plant model of the CCPP. The method may include modifying the variant control profile in response to the variant control profile not reducing the fuel consumption or meeting the quality threshold. The method may also include adjusting the CCPP to use the variant control profile in response to the variant control profile reducing the fuel consumption and meeting the quality threshold. Using the variant control profile adjusts a turbine section inlet temperature schedule or an exhaust temperature schedule for the CCPP.

Modeling and control of gas cycle power plant operation with variant control profile

A flexible and automatic system and method for blending an inexpensive secondary gas with a primary gas fuel for operation of a Dry Low NOx gas turbine. The secondary gas may be a gas fuel such as hydrogen, ethane, butane, propane and liquefied natural gas or an inert gas. Combustion dynamics are avoided by controlling the blended fuel within a permissible range for a Modified Wobbe Index. Combustion dynamics and gas turbine exhaust emissions may also be monitored to maintain safe combustion with the blended fuel. A gas turbine control system may adjust the blend and temperature of the primary gas fuel and the secondary gas to promote desired combustion.

System and method for automatic fuel blending and control for combustion gas turbine

A method for operating a pressurized solid oxide fuel cell/turbine (SOFC/turbine) hybrid power generation system in which the hybrid power generation system includes an SOFC generator and a turbine generator includes controlling airflow to the SOFC/turbine hybrid power generation system in accordance with power demand and utilizing electrical current drawn from the SOFC generator to regulate SOFC generator temperature.
