Combined economic emission dispatch with new price penalty factors

This paper presents combined of economic and emission load dispatch (CEED). The price penalty factor is considered in the multi-objective function of (CEED). In this paper, we use various price penalty factors (Max/Max, Min/Max and average). Simulated annealing method is our method to find the optimal solution. The SA algorithm is used to minimize the fuel cost and the gas emissions as SO2 and NOx in the power systems. In this study, in order to evaluate the performance of the SA algorithm, it is tested on 3-unit system with fuel cost and emission functions. The results obtained from SA method are compared with other method in literatures. The results show that the SA algorithm is better than the others at solving such a problem.
