The generation of electric energy from the thermal plants needs the combustible fuel to move the turbines. These power plants exist for more than 100 years. As a result, the combustible fuel emites some gas like NOx, SO2, and CO2 to the atmosphere. These gas emissions make an impact on environment (air pollution and water pollution). This paper presents a simulated annealing optimization for finding economic production with control pollution in the thermal plants. The paper formulates a multi objective dispatch problem with valve point effect considered in both fuel cost and emission functions. The multi-objective problem of the generation and emission dispatch is solved to find the generation levels that best compromise the generation cost and the emission level while satisfying the power balance constraint. The simulated annealing algorithm from is tested on a 10 generator test system with valve point effect. The results of the proposed method are compared with other techniques reported in recent literature.
