Simulation and Optimization in an AGC System after Deregulation

Vaibhav Donde, M. A. Pai, Fellow, IEEE, and Ian A. Hiskens, Senior Member, IEEE

Abstract—In this paper, the traditional AGC two-area system is modified to take into account the effect of bilateral contracts on the dynamics. The concept of DISCO participation matrix to simulate these bilateral contracts is introduced and reflected in the two-area block diagram. Trajectory sensitivities are used to obtain optimal parameters of the system using a gradient Newton algorithm.

Index Terms—Automatic generation control, bilateral contracts, deregulation, optimization, power system control, trajectory sensitivity.
