Optimal Schedule for Hydro-thermal Energy System including Environmental Impacts

Abstract

This paper proposes a scheme for scheduling of a multi-generation system (like hydrothermal system) to minimize both operating cost and dispersion of emission from the stack subjected to all system constraints. The amount of the emission that finally reaches the recipient at the ground level is the root cause of the health diseases. Therefore, the proposed algorithm tries to minimize the environmental impact caused by the thermal power plants using a day ahead hydrothermal schedule. The impact is realized using gauss dispersion model while the multiobjective optimization problem is solved using NSGA-II algorithm.
