Optimal location of FACTS devices for damping oscillations using residue factor

Abstract

This paper proposes a residue method to find the optimal location of the FACTS controllers to damp out the inter-area mode of oscillations. Three types of FACTS controllers have been considered, which include static var compensator, thyristor-controlled series compensator and unified power flow controller. The residue method is base on the facts that it is the product of the mode's observability and controllability index of FACTS controllers to the critical mode. The placements of FACTS controllers have been obtained for the base case and placement base of loss sensitivity is also introduced. The effectiveness of the proposed method is demonstrated on two area 11 bus systems and New England 39-bus system.

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

“…A new approach based on sensitivity indices has been used for the optimal placement of various types of FACTS controllers such as TCSC, TCPAR and SVC in order to minimize total system reactive power loss and hence maximizing the static voltage stability in [201]. Magaji and Mustafa et al [43] has been suggested a residue factor approach for optimal location of FACTS devices for damping oscillations of power systems. An opening of unused potentials of transmission system due to environmental, right-of-way and cost problems is a major concern of power transmission network expansion planners and policy makers.…”

“…References [3]- [5], classify three broad categories such as a sensitivity based methods, optimization based method, and artificial intelligence based techniques for placement of FACTS controllers from different operating conditions viewpoint in multi-machine power systems. The various sensitivity based methods have been proposed in literatures includes eigen-value analysis based methods [6]- [12], modal analysis techniques [13]- [15], index methods [16]- [23], residue-based methods [24]- [25], [43], [168], [169], and other sensitivity based methods [26]- [37], [53], [157]- [167], [201].…”

Bacterial foraging optimized STATCOM for stability assessment in power system

“…Fig.1 (b) represents the linearized block diagram of a SMIB system with STATCOM. Linearized model was considered in order to study the low frequency transient stability oscillations with a smaller variation of load [9], [11].…”

A Highly Relevant Method for Incorporation of Shunt Connected FACTS Device into Multi-Machine Power System to Dampen Electromechanical Oscillations

“…Contrasting to the heuristic methods, some authors proposed the analytical methods. For example, Sadikovic et al, Magaji et al [23,24] have proposed the residue factor method to damp inter-area mode of oscillations. Kunnar et al [25] have utilized the modal controllability index to dampen inter-area oscillations.…”
