Unit Commitment: A New Truncated Method of Unit Combination
Abstract
The utility industry can reduce its fuel cost by proper commitment of schedulable generating unit. In this paper, a new truncation of unit combinations is proposed which will greatly reduce the number of unit combinations to be considered for large systems. A dynamic programming optimization based digital computer program has been developed for this new approach.
Data obtained from the National Electric Power Authority (NEPA) has been used to test the efficacy of this approach. The results indicate a significant reduction in cost over the method of just considering the first N possible unit combinations generated by binary powers.
