ABSTRACT
The economic dispatch problem plays an important role in power system operation. The principal objective of ED is to obtain the minimum operating cost needed to satisfy power balance, generator and network operating limit constraints. The optimal operating point of a power generation system is where the operating level of each generating unit is adjusted such that the total cost of delivered power is at a minimum. In an energy management system (EMS), Economic Dispatch (ED) is used to determine each generating level in the system in order to minimize the total generator fuel cost or total generator cost and emission of thermal units while still covering load demand plus transmission losses [1].
