Abstract


In this paper, unit commitment (UC) problem with POZ constraint is proposed. A simple dynamic programming method is used to UC. Various constraints such as power balance, minimum up time & down time, ramp up & down, next hour load and most specifically prohibited operating zone constraint is also considered. The results are extensively validated for IEEE 10 units and 6 units. The results obtained are compared without POZ constraint. The promising results obtained are presented.
