Abstract: In this paper, the Unit Commitment (UC) problem has been solved using Dynamic Programming (DP).The test results of conventional Dynamic Programming and Modified Dynamic Programming are compared. The commitment is such that the total cost is minimal, which is non-linear function. The total cost includes both the production cost and the costs associated with start-up and shutdown of units. DP is an optimization technique which gives the optimal solution.

Keywords: Unit Commitment, Dynamic Programming (DP), Modified Dynamic Programming, Non-linear.
