Coordinated Application of Stabilizers in Multimachine Power Systems

A Comprehensive Survey of Optimal Placement and Coordinated Control Techniques of FACTS Controllers in Multi-Machine Power System Environments

“…The response is carried out by the coordination of multiple type FACTS controllers, which compensate the reactive power, improving the voltage stability margin of the critical modes [87]. In [88], an eigen value analysis approach has been addressed for the problem of the most effective selection of generating units to be equipped with excitation system stabilizers in multi-machine power systems which exhibit dynamic instability and poor damping of several inter machine modes of oscillations. A new coordination synthesis method using as an eigen value sensitivity analysis and linear programming has been addressed for simultaneous able to select the generators to which the PSS can be effectively applied and to synthesize the adequate transfer function of the PSSs for these generators [89].…”

“…Three broad categories such as a sensitivity based methods, optimization based method and artificial intelligence based techniques for coordination of FACTS controllers from different operating conditions in multi-machine power systems is classified in [5]. The various sensitivity based methods have been proposed in literatures includes eigenvalue analysis based methods [11], [88]- [96], [181]- [182], modal analysis techniques [97]- [103], residue-based methods [104], [105]. There are various other techniques such as a pole placement techniques [106], frequency response techniques [107], root locus techniques [108], projective control methods [109]- [111], [200], non-linear feed control methods [112]- [113] for coordination of FACTS controllers and PSS.…”

Survey on power system stabilizers control and their prospective applications for power system damping using Synchrophasor‐based wide‐area systems

“…In [86], a study using eigenvalue analysis for selecting the most effective locations of PSSs in multi-machine systems was conducted. Another method for determining controller locations is to use modal controllability.…”

Design of Robust Power System Stabilizer in an Interconnected Power System with Wind Power Penetrations

“…In (Abdalla et al, 1984), an eigenvalue-based measurement of relative improvement in the damping of oscillatory modes has been implemented and used as a criterion to find the best candidate machine for stabilizer application. On the other hand, an eigenvector analysis to identify the most effective generating units to be equipped with PSSs in multi-machine systems that exhibit dynamic instability and poor damping of several inter-area modes of oscillations, has been presented in (DeMello et al, 1980). Nowadays, the conventional lead/lag compensator PSS is widely used by the power system utility (Tse & Tso, 1993).…”
