Multi-Objective Power Scheduling of Wind-Thermal Integrated System by Using α-Constrained Simplex Method

While meeting the growing power needs of the world, use of fossil fuels has increased so much that the crises of their looming has raised now. Along with that, global warming and air pollution are also the matters of great worries for humans. All these problems can be reduced by enhancement of utilization of renewable energy resources in power generation. In many parts of the world, wind energy is present in sufficient quantity. Just one percent of wind power in the world is equivalent to 2 X 10(11) W, which is about three percent of total world energy consumption rate. Role of wind energy in power generation field is increasing day by day because evolved technologies and power management techniques have started suppressing its shortcomings. In this paper, multi-objective wind-thermal power scheduling problem has been proposed and it is optimized by using alpha-constrained simplex method to satisfy economic and emission (NOx, SO2&CO2) constraints. The credibility of presented method has been corroborated on five test systems.
