Claim 19:
20. A non-transitory computer-readable medium having stored thereon executable instructions that, in response to execution, cause a power plant controller comprising at least one processor to perform operations directed to controlling operation of a power plant having at least one gas turbine, the operations comprising:
operating the power plant at an ambient condition and a load condition;
obtaining a flexible base load map for operating the power plant to meet base load power demands, wherein the flexible base load map includes a primary base load operating space for attaining target plant power output and efficiency, and an expanded base load portion for attaining higher plant power output and sub-optimal efficiency in relation to the primary base load operating space, both the primary base load operating space and the expanded base load portion including a representation that associates power output and efficiency values of the power plant that result from a subset of operational parameter values for operating the power plant during base load, the operational parameters including firing temperature of the at least one gas turbine, a position of inlet guide vanes in the at least one gas turbine, and fuel temperature of the fuel in the at least one gas turbine;
partitioning the flexible base load map into a plurality of operating segments, each operating segment including a range of operating values for the operational parameters and corresponding power output and efficiency values that are attained while operating the power plant at the range of operating values in the operating segment;
for each of the plurality of operating segments, determining revenue that is generated from operating the power plant over the range of operating values that attain the corresponding power output and efficiency values taking into consideration at least one of a plurality of market conditions associated with a power generation market;
generating a plurality of visualizations of the revenue associated with each of the operating segments in the partitioned flexible base load map for each of the plurality of market conditions, wherein each visualization of the revenue determined for the plurality of market conditions includes a visual representation of the revenue associated with operating the power plant in each of the plurality of operating segments based on the respective range of operating values and power output and efficiency values that are attained with the operating values;
presenting for display one or more of the plurality of visualizations of the revenue associated with each of the operating segments in the partitioned flexible base load map for each of the plurality of market conditions; and
adjusting the operation of the power plant in response to the obtaining of the flexible base load map, the partitioning of the flexible base load map into the plurality of operating segments, the determining of the revenue for each of the plurality of operating segments, and the presenting of the one or more of the plurality of visualizations of the revenue associated with each of the operating segments, wherein the adjusting of the operation of the power plant includes automatically adjusting at least one of the firing temperature, a Mach number, and/or fuel temperature of the at least one gas turbine.
