Afandi, A.N. Abstract. 2014. Since the economic power system operation (EPSO) is concerned to decrease the running charges of electric energy with considering the environmental protection for decreasing
atmospheric emissions from pollutant productions at thermal power plants, the combined
economic and emission dispatch (CEED) problem is helpful to decide the EPSO in financial
aspects based on the minimizing total fuel cost and the total pollutant reduction. This paper
presents impacts of the emission standard (EmiStd) in the CEED related to pollutant productions
and allowed emissions in the EPSO. Moreover, the CEED has been demonstrated in different
performances depended on the emission standard (EmiStd) scenarios for power outputs and total
costs. These schemes have also presented in different characteristic computations. Based on the
EmiStd scenarios, pollutant emissions have been produced totally around 12,127.45 kg/h to
14,570.74 kg/h. These pollutions have been allowed totally to discharge around 2,724.16 kg/h to
3,685.48 kg/h related to the EmiStd. In addition, total operating costs have been optimized around
17,439.47 $/h to 18,157.39 $/h considered the allowed emission. (The 20th International Conference on Electrical Engineering, June 15-19, 2014 Jeju, Korea)
