Abstract:

 

This paper presents a new approach with a three-stage optimization algorithm   for the least-cost optimal solution of the unit commitment problem. In the   proposed work, the optimal schedule is obtained by optimizing the lambda   operator for the states that violate the inequality constraints. The   objective of the work is to minimize the fuel cost when subjected to various   constraints such as load balance, minimum up/down time, ramp limit, and   spinning reserve. This method of committing the units yields the least-cost   solution when applied to the IEEE 10-unit systems and 7-unit Indian utility   practical systems scheduled for 24 h and the results obtained are compared   with the existing methods.
