Best location of SVC to improve first swing stability limit of a power system

Bacteria Foraging Optimization Algorithm based SVC damping controller design for power system stability enhancement

“…A multi input, single output fuzzy neural network is developed in [9] for voltage stability evaluation of the power systems with SVC. A method of determining the location of a SVC to improve the stability of power system is illustrated in [10]. A systematic approach for designing SVC controller, based on wide area signals, to improve the damping of power system oscillations is presented in [11].…”

A new method for SVC placement considering FSS limit and SVC investment cost

“…Control strategy used in [17] is based on SVC performance at its full capacitive rating in the early part of post fault period until the severely disturbed machine is on the way of returning to SEP after reaching the maximum angle during the first swing. Therefore, the SVC is represented by its maximum capacitive susceptance B max SVC À Á at the verge of stability where the critical energy is evaluated.…”

“…In the case of disturbance, system is stable if its variables are close to the steady state values when time goes to infinity. In transient stability studies, improvement of the FSS limit is very important since a first swing stable system can be considered mainly stable if the system has adequate damping in subsequent swings [17].…”

Multiobjective optimal placement and sizing of SVC using cultural algorithm

“…Comparison of PSS, SVC and STATCOM controllers for damping power system oscillation is also worked out elsewhere [11]. Using SVC, swing stability limit is analyzed by Haque [12]. Congestion management using FACTS devices has been studied also by Singh et al [13].…”
