This paper presents an implementation of fuzzy-logic to solve the unit-commitment problem of thermal generation plant with the main objective of obtaining a feasible unit combination for each loading condition while subjected to a variety of constraints. The model in this study contains ten-generation units and the daily load demand is subdivided into 24 intervals. The unit combinations and the corresponding generation scheduling intend to minimize the operating cost. The implementation of fuzzy-logic allows a qualitative description of the behavior of the system: the system's characteristics and the response without the need for exact mathematical formulations. The numerical values obtained by the fuzzy-logic approach are compared with those obtained by the dynamic programming. The results have shown that the proposed fuzzy-based approach provides feasible combinations of the generation units and economical cost of operation of these units and have also shown the superiority of the proposed fuzzy-logic approach over the dynamic programming.
