Dynamic economic dispatch of electric power incorporating transmission line costs

The Dynamic Economic Dispatch (DED) mathematical formulation in its basic form is concerned with determining the amount of power to be produced by committed generators whilst respecting all the available physical and power system constraints. In the basic DED formulation the objective function is to minimize the operating costs of the thermal units over a scheduling horizon. In this paper, the DED problem is considered with transmission costs included in the objective function and transmission line flow constraints added to the basic DED operational constraints. The power flow in the transmission lines are modeled as a product of the thermal generator outputs and generation distribution factors. The resulting mathematical formulation is modeled on the IEEE 30 Bus system and solved using the Advanced Interactive Multidimensional Modelling System (AIMMS).
