“…SVCs are part of the Flexible AC transmission system device family, regulating voltage and enhance the transient stability [11] and provide additional damping to power systems as well [12]. SVC is mainly operated at load side bus and used as replacement for existing voltage control devices [10].…”

In this paper, the Authors present the designing of Power System Stabilizer (PSS) and Static Var Compensator (SVC) based on Chaos, Particle Swarm Optimization (PSO) and Shuffled Frog Leaping (SFL) Algorithms has been presented to improve the power system stability. Single Machine Infinite Bus (SMIB) system with SVC located at the terminal of generator has been considered to evaluate the proposed SVC and PSS controllers. The coefficients of PSS and SVC controller have been optimized by Chaos, PSO and SFL algorithms. Finally the system with proposed controllers is simulated for the special disturbance in input power of generator, and then the dynamic responses of generator have been presented. The simulation results show that the system composed with recommended controller has outstanding operation in fast damping of oscillations of power system and describes an application of Chaos, PSO and SFL algorithms to the problem of designing a Lead-Lag controller used in PSS and SVC in power system.

In this paper, a Fuzzy Logic Controller (FLC) is proposed for Thyristor Controlled Phase Shifter (TCPS) to improve power system dynamic performance. The FLC has been designed for the TCPS which is located at the terminal of the generator in order to damp the Low Frequency Oscillations (LFO). From the first, for normal loading condition, the system with proposed controller has been simulated while the input power of generator has been changed suddenly, then the dynamic responses of generator have been presented with and without controller. Thereafter, for two states viz normal loading condition and heavy loading condition, to show the robustness of proposed controller, the system with previous disturbance has been simulated, then the dynamic responses of generator have been shown. The effectiveness of the proposed controller is demonstrated by simulation results.I.

“…With the advance in the application of differential geometric techniques to control system design, the feedback linearizing control (FLC) has been introduced for power system control and has already made significant progress as can be seen in generator control (7) (8) , FACTS device (e.g. SVC, STATCOM) (9) (10) and HVDC system (11) . FLC is not the approximated linearization as in the linear control methods; there is no disadvantage of linear control methods mentioned above.…”

MemberThere are 50 Hz and 60 Hz power systems in Japan, which are interconnected by power electronics based static type frequency converter station. Frequency converter can be realized by using Adjustable Speed Generators/Motors (ASGMs), which are excited by AC voltage, and so-called rotary type frequency converter. The rotary type frequency converter can also function as a power system stabilizer by effectively utilizing rotational energy stored in rotors. Nonlinear excitation control for the rotary type frequency converter is proposed to enhance performance of the rotational energy utilization and to improve stability of power system. The control performance is examined for a power system model by digital dynamic simulation. It is made clear that the proposed nonlinear excitation control is effective even though local information of the rotary type frequency converter is just used and that it has robustness against various load flow conditions.
