Economic Fuel Dispatch

The economical use of all types of fuels available for the generation of power has become a major concern of electric utilities. Present methods do not fully take advantage of standard economic load dispatch minimization techniques because the fuel constraints on each type of fuel are not considered-in the classical calculation. Presented herein is a minimization technique that includes the standard load constraints as well as the applicable fuel constraints. The technique is as it would be applied to real-time control of a power system participating in short-term fuel management by automatic means.
