Commitment of units for daily operations

The development of a unit commitment method is presented, and also its implementation in program form. The method presented satisfies the many operating constraints which are listed in detail. An Interactive Processing version of the program is available and is used in committing units on a system containing 100 machines. It is also employed by operating personnel in evaluating the effect on economy and security of the system by changing the operating rules, reserve requirements, unit additions and outages, unit limitations, and interchanges. The savings realizable over manual methods are reported to be in excess of 1% of the total fuel cost.
