A Unit Commitment Study considering Generation System Reliabilty |
| Abstract |
This paper proposes an improved unit commitment algorithm for the purpose of rational operation of electric power systems. Security function is introduced to consider generation system reliability as well as economical properties in the algotithm . As a stte model for assessment of state probabilities, the 3-state model in which the probability of the units for commitment can be considered is proposed and applied, so that the algorithm becomes more practical and reasonable one. A decision bounding scheme which can be applied to all kinds of system is described and the numerical results obtained for KEPCO and model systems are also presented to assure the availability of the proposed technique. |
