Emission dispatch solution using biogeography-based optimization with availability of wind power

In this paper a emission dispatch problem is solved to minimize the emission of oxides of nitrogen (NOx), considering both thermal generators and wind power source. Total overall cost of generation is taken as inequality constraint during the time of minimization of emission during optimization process. The effects of wind power to control overall NOx emission from thermal power plants are also investigated here. To find the optimum emission dispatch schedule, authors have applied Biogeography based optimization. Biogeography deals with the geographical distribution of biological species. Mathematical models of biogeography describe how a species arises, migrates from one habitat to another and gets wiped out. The results obtained using BBO show the efficiency of BBO algorithm to solve complex emission dispatch problems.
