Abstract :
Ant colony system (ACS) is more suitable for hard combinatorial optimization problems. So ACS has been applied to unit commitment problem (UCP). The UCP is solved with power flow constraints. Also to make the system function in a realistic environment, white Gaussian noise (WGN) is added to the network nodes with proportional loads to the demand forecasted at each hourly stage. Multi-stage decisions give ant search competitive over other conventional techniques. The proposed model is tested on IEEE 30 bus system and has been compared with dynamic programming (DP) and branch and bound integer programming (BBIP) approaches
