Structural control for overlapping interconnected power systems

A structural control methodology is proposed for automatic generation control (AGC) of power systems with the multi-area overlapping interconnected information structure constraint. To derive the structural controllers preserving information structures of the system, restriction conditions of the inclusion principle are considered in the framework of topological structure for the original and its expanded systems. The application of the proposed controllers to a four-area overlapping interconnected power system AGC is presented to illustrate the performance of the new AGC design.
