In this paper, an algorithm to solve environmental constrained unit commitment problem (UCP) with operational and power flow constraints has been developed to plan an economic and secure generation schedule. Both economic load dispatch (ELD) and economic emission dispatch (EED) have been applied to obtain optimal fuel cost and optimal emission of generating units for the entire time horizon. The unit...
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...
