Abstract :

This paper presents a new optimization algorithm i.e gravitational search algorithm (GSA) based on the law of gravity and mass interactions for solving the Unit Commitment problem in hydro thermal large power system with cooling –banking constraint for a duration of one day having 24intervals such that total operating cost can be minimized satisfying both the load balance constraint and other operating constraints of hydro and thermal systems. Numerical results for a test case show that GSA algorithm is capable of finding very nearly global solutions and achieves cheaper generation schedule in comparison to the results of the other heuristic optimization techniques reported in literature.
