This paper presents a novel optimization based methodology to allocate Flexible AC Transmission Systems (FACTS) devices in an attempt to improve the previously mentioned researches in this field. Static voltage stability enhancement, voltage profile improvement, line congestion alleviation, and FACTS devices investment cost reduction, have been considered, simultaneously, as objective funct...

Voltage-sourced converter (VSC) based FACTS controllers are capable of providing fast voltage support and active power flow control to improve the power transfer capability over congested transmission paths. In most published literature, a shunt VSC such as a Static Synchronous Compensator (STATCOM) is set to control the bus voltage and a series VSC such as a Static Synchronous Series Compensat...

This paper presents a new design of scattering transformation-based wide-area damping controller for static synchronous series compensator (SSSC) to enhance power system stability in the presence communication latency. The proposed control approach is comprised classical structure addition two transformation ports. These ports are inserted between and (WADC) regulate signal exchange. Since WADC...

In this study, a fuzzy gain scheduled proportional and integral (FGPI) controller was developed to regulate the power flow regulation of Static Synchronous Series Compensator (SSSC) in a multi-area power system. Also, this FGPI was developed for the SSSC without and with Superconducting Magnetic Energy Storage (SMES) system. Two performance criteria were utulized for the comparison. First, sett...

The low frequency electromechanical oscillations have been observed in many power systems and have resulted in system separation on several occasions. The main objective of this paper is to damp out the power angle oscillations of a two-area power system using Power System Stabilizers (PSSs) and Static Synchronous Series Compensator (SSSC) controllers. In this paper, the damping performances of...

This paper proposes a new genetic based approach for optimal selection to damp power system oscillations by a Static Synchronous Series Compensator (SSSC) based controller. The design problem of the proposed controller is formulated as an optimization problem and modified Genetic Algorithm (MGA) is employed to search for the optimal controller parameters. The performances of the proposed contro...

A systematic procedure for modeling, simulation and optimally tuning the parameters of a Static Synchronous Series Compensator (SSSC) controller in a multi-machine system, for power system stability enhancement is presented in this paper. For the simulation purpose, the model of multi-machine power system with SSSC controller is developed in MATLAB/SIMULINK using Sim Power System (SPS) blockset...

Power-system stability improvement by a static synchronous series compensator (SSSC)-based controller is studied in this paper. Conventionally, the lead-lag structure was used to modulate the injected voltage. But, in this paper PI, PID, PIDD structures are proposed to modulate the injected voltage. The design problem of the proposed controller is formulated as an optimization problem and Diffe...
