“…The FACTS devices, through the modulation of bus voltage, phase shift between buses, and transmission line reactance, can cause a substantial increase in power transfer limits during steady state. Because of the extremely fast control action associated with FACTS device operations, they have been very promising candidates for utilization in power system damping enhancement [5]. It has been observed that FACTS based supplementary controller can considerably improve system damping and can also improve system voltage profile, which is advantageous over PSSs.…”

“…For many years, fixed and controlled series compensators have been used in transmission lines for compensating the line reactance in order to increasing power transfer capability and enhancing the transient stability in power networks. The conven-tional series FACTS devices proposed in the literature can be classified in two major groups: thyristor controlled reactance [12] and synchronous controllable voltage sources [5]. However, in recent years new devices based on AC link converters have been proposed [6][7][8][9].…”

Original scientific paperPulse Width modulated based Series Compensator (PWMSC), a newly FACTS device, can modulate the impedance of a transmission line through the variation of the duty cycle of a train of pulses with fixed frequency, resulting in improvement of system performance. In this study, a current injection model of PWMSC is proposed and incorporated in the transmission system model. The purpose of the work reported in this paper is to design an oscillation damping controller for PWMSC to damp low frequency oscillations. We have used the residue method to the linearized equations of the power system for multiple operating conditions and obtained a generalized form which is suitable for different damping controller input-output channels and therefore suitable for different control devices. The case study results show that the proposed controller is very effective to mitigate the power system critical modes of oscillation.

Abstract-In this study alinearized Heffron-Phillipsmodel of a single machine power system installed with a unified power flow controller (UPFC) has been presented. The selection of the output feedback parameters for the UPFC controllers is converted to an optimization problem which is solved by cuckoo optimization algorithm (COA).COA, as a new evolutionary optimization algorithm, is used in multiple applications. This optimization algorithm has a strong ability to find the most optimistic results for dynamic stability improvement. The effectiveness of the proposed controller for damping low frequency oscillations is tested and results compared with imperialist competitive algorithm (ICA).The controllers are tested to variations in system loading. There sulks analysis reveals that COA minimized cost function and improved dynamic stability, better than ICA. In addition, the potential and superiority of the proposed method over the ICA is demonstrated. The simulation results analysis shows that the designed COA based output feedback UPFC damping controller has an excellent capability in damping low frequency oscillations and enhance rapidly and greatly the dynamic stability of the power systems.

Abstract-In this paper, on the basis of the theoretical analysis of a single-machine infinite-bus (SMIB), using its modified linearized Phillips-Heffron model installed with SSSC, the potential of the SSSC supplementary controller to enhance the dynamic stability of a power system is evaluated by measuring the electromechanical controllability through singular value decomposition (SVD) analysis. This controller is tuned to simultaneously shift the undamped electromechanical modes to a prescribed zone in the s-plane. The problem of robustly SSSC based damping controller is formulated as an optimization problem according to the eigenvalue-based multi-objective function comprising the damping factor, and the damping ratio of the undamped electromechanical modes to be solved using particle swarm optimization technique (PSO) that has a strong ability to find the most optimistic results. To ensure the robustness of the proposed damping controller, the design process takes into account a wide range of operating conditions. The effectiveness of the proposed controller is demonstrated through controllability measure, eigenvalue analysis, nonlinear time-domain simulation and some performance indices studies. The results analysis reveals that the tuned PSO based SSSC controller using the proposed multi-objective function has an excellent capability in damping power system low frequency oscillations and enhance greatly the dynamic stability of the power systems.Index Terms-Power system dynamic stability, Power transmission control, particle swarm optimization, static synchronous series compensator.
