| Abstract | ||||
| The paper presents two different schemes to design controllers for interconnected power systems. The first scheme adopts two-level control concept, where the “lower” first level design is based on optimizing the decoupled subsystems, then eigenstructure (eigenvalues and partial eigenvalues) assignment approach is adopted to design the “higher” second level controller. The proposed two-level control preserves the autonomy of subsystems for sharing the assignment process, and suits power system stabilizers design. The proposed scheme can achieve robustness via eigenvector selection. The proposed second scheme proposes a proportional plus integral controller which is commonly used for load frequency control. The design procedure is based also on eigenvalues assignment. Two illustrative numerical examples are presented to prove the effectiveness of the procedure where the results indicate that the proposed control scheme works well. | ||||
