Eigenvalue Sensitivity Analysis for Dynamic Power System

Eigenvalue sensitivity analysis has been an effective tool for power system controller design. However, research on eigenvalue sensitivity with respect to system operating parameters is still limited. This paper presents new results of an eigenvalue sensitivity analysis with respect to operating parameters, preceded with a comprehensive review on eigenvalue sensitivity analysis and applications during the last few decades. The method is based on explicit expression of the derivatives of augmented system matrix with respect to system operating parameters. IEEE 5-machine 14-bus system is used to demonstrate the effectiveness of the method. The eigenvalue sensitivity analysis provides useful information for power system planning and control.
