, voltage fluctuations, and harmonics, cannot be solved satisfactorily by them because these devices are not fast enough [ 6 ]. Therefore, a dynamic shunt reactive power compensator is needed to address these issues more effectively. This can be achieved by using Flexible AC Transmission System (FACTS) devices such as the Static Var Compensator (SVC)and static synchronous compensator (STATCOM). SVC is being used extensively in power systems as it is simple and robust device in view of power system dynamic stability point. SVC can perform various tasks, such as regulating

Particle Swarm optimization method for a multi-objective function using SVC to improve transmission system loading margin (LM) to a certain degree and reduce network expansion cost. Rao et al. [ 8 ] have used OPF technique in the presence of SVC for the improvement of network security under contingency condition. The performance of BAT and Firefly algorithm have been compared to find the optimal location and size of Static VAR Compensator (SVC) in a power system for a multi objective function to improve voltage stability. Khandani et al. [ 10 ] improved the voltage

controllers, shunt compensation devices like static var compensator (SVC) is simple and robust device in view of power system dynamic stability point. SVC can perform various roles in stability studies, such as scheduling power flow, reducing net power loss, providing voltage support, damping the power oscillations, and can enhance over all stability of the system. SVC is thyristor-based controller, by controlling the effective reactive admittance, the SVC will control the power transfer. Particle swarm optimization (PSO) technique, developed by Kennedy and Eberhart [ 4

Srivastava Abstract This paper presents a sensitivity based approach to determine optimal location of Static VAR Compensator (SVC) for voltage security enhancement. The proposed approach of SVC placement computes sensitivity of system loading factor with respect to reactive power generation, derived from reactive power balance equation. This sensitivity factor has been termed as Bus Static Participation Factor (BSPF). The

the high variations in their voltage profile. The Static VAR Compensator (SVC) is a type of FACTs that will be used in this paper. It is a power-electronic device capable of absorbing (or injecting) reactive power from (or to) the grid; thus, controlling the system voltage within acceptable tolerance. Alternatively, Static Synchronous Compensator (STATCOM) [ 3 ] and Unified Power Flow Controller (UPFC) belong to the same family of devices and may be used to enhance the operation of fixed-speed wind farms [ 4 ]. In general, to enhance the performance of a typical

Controller for a SVC Compensating Unbalanced Fluctuating Loads A. Rajapakse and Anawat Puangpairoj Abstract This paper presents the development of an artificial neural network (ANN) controller for a Static Var Compensator (SVC) system compensating unbalanced fluctuating loads. The proposed controller can balance and reduce the reactive power drawn from the source under unbalanced loads while keeping harmonic injection to the system due to SVC operation low. The first stage of controller development is a fuzzy logic based control algorithm. This algorithm determines a

Improvement the work effectivenes of static var compensators by using of two-input adaptive controllers

In the paper is suggested a two-input adaptive controller for control of static var compensator (SVC). The controlling system of adaptive controller is identifying in real time of the basis for estimated parameters and variables of identification model and after that controlling signal is created for the compensator. As result of this controlling is improving vastly damping of power system like all performances as in transient processes as in steady state mode are improved.

-Light transmission in exploiting the Off-shore wind energy resources. KEYWORDS: wind energy, wind farms, reactive power, static VAR compensators (SVC), STATCOM, UPFC, HVDC 1. Introduction The increasing power demand has led to the growth of new technologies that play an integral role in shaping the future energy market. Keeping in view the environmental constraints, grid connected wind parks are a promising aspect in increasing system reliability and congestion relief [1]. Wind farms are either connected to the grids or a stand-alone operation. With the ever changing
