It is well known that power system stabilizers (PSSs) may cause adverse impacts to the transient performance of generator terminal and field voltages when they are not properly designed. This fact, in special for distribution networks with synchronous generators, is relevant from the voltage quality point of view since the operation of sensitive equipments connected to the network may be deteriorated...
Power system low frequency oscillations are detrimental to the stability and security of interconnected power networks. The recent advance in the wide area measurement system (WAMS) is driving power community to accept the notion of wide area monitoring and control. This paper proposes the placement of wide area PSSs and the selection of stabilizing signals based on improved residue matrices. Modal...
Wide-area controllers have been proposed to enhance the dynamic performance of large interconnected power systems. The time delay existing in the data communication may be a detriment to wide area control system stability. This paper analyzes the effect of time delay on the additional interarea damping control (AIADC) design of PSS. The AIADC is proposed for generators' excitation controllers and...
This paper presents an approach for designing coordinated controllers of power system stabilizers (PSSs) and FACTS devices stabilizers for enhancing small-disturbance stability. The control co-ordination problem is formulated as a constrained optimization with eigenvalue-based objective function without any need for the linear approximation by which the sensitivities of eigenvalues of state matrix...
