Dynamic Economic Dispatch with Generator's Feasible Operation Region

摘要

Dynamic economic load dispatch is an extension of the conventional static economic load dispatch which takes into account the ramp rate of generating units. This paper proposes a dynamic economic load dispatch method based on the feasible operation region approach. The region defines how generating units may change their outputs in order to match a demand profile. It is defined by physical and ramp rate constraints of generating units and supply-demand balance constraint. The proposed method has been successfully tested on a 3 generator system supplying a typical afternoon demand profile.
