TLDR
In this article, a new coordinated synthesis method of applying power system stabilizers (PSS) was developed by combining eigenvalue sensitivity analysis and linear programming, which is simultaneously able to select the generators to which the PSS can be effectively applied and to synthesize the adequate transfer functions of the PS for these generators.Abstract:
A new coordinated synthesis method of applying power system stabilizers (PSS) was developed by combining eigenvalue sensitivity analysis and linear programming. This method is simultaneously able to select the generators to which the PSS can be effectively Applied and to synthesize the adequate transfer functions of the PSS for these generators. The proposed itethod is used to synthesize the coordinated PSS for a 12-machine system.read more

A sequential conic programming approach for the coordinated and robust design of power system stabilizers
Abstract: This paper shows that conic programming is an effective tool to solve robust power system stabilizer (PSS) design problems, namely coordinated gain tuning and coordinated phase and gain tuning. Design robustness is achieved by simultaneously considering several operating scenarios. The method is implemented through a sequence of conic programming runs that define a multivariable root locus along which the eigenvalues move. Specifically, the eigenvalues corresponding to the unstable and poorly damped modes are moved to a conic sector in the left half of the s-plane, whereas the eigenvalues corresponding to the well damped modes are constrained to stay within the boundaries of this conic sector. At each step of the solution, the PSS design parameters are restricted in a trust-region such that the computation of the eigenvalue shift based on the residue method holds valid. The proposed method is demonstrated on a 68-bus test system with nine different operating conditions. Comparisons are carried out between conic programming implementations for PSS coordinated gain tuning and for simultaneous tuning of gain and phase characteristics.
