Unit commitment problem (UCP) is complicated non-linear optimization strategy for the scheduling of power generating units. The emission constrained unit commitment problem (ECUCP) is used to acquire the switching status of generating units by incorporating different equality and inequality system constraints. The equality and inequality constraints are power generating limit; maximum allowable emissions limit of the generating units; minimum up/down duration and as well as spinning reserve constraints of the generating units. In this research; Modified Differential Evolution (MODE) optimization techniques have been implemented for solving the emission constrained unit commitment problem (ECUCP). Modified Differential Evolution (MODE) is an evolutionary algorithm in which initial population of the feasible appellant is created randomly. MODE has three operators for searching the global best solution i.e. modified Gaussian mutation; crossover and selection. The result of emission constrained unit commitment problem (ECUCP) has validated on IEEE 30 bus 6 generating unit systems and numerical solution has proved MODE as efficient optimization technique.
