“…Hence in the recent years, in order to reduce the existing interactions and to promote the performance level of the power systems, the researchers' approach has been directed towards the simultaneous design of FACTS and PSS controllers instruments, some of which to be mentioned are: Static VAR Compensator (SVC), Static Synchronous Series Compensator (SSSC), Static Synchronous Compensator (STATCOM), etc [6][7][8][9].In this paper, simultaneous control of PSS and another product of the FACTS family that is TCSC, have been taken into consideration. Thyristor controlled series compensator (TCSC) as one of the FACTS controllers is used to increase the stability and damping of the oscillations in the power systems [10][11][12]. TCSC can take up different roles in the power system some of which to be mentioned are: power system damping, increasing the transmission capacity from the line, transient stability improvement, fault current limiter and sub-synchronous resonance damping [13].…”

Due to the development of power networks and the ever increasing use of Flexible AC Transmission Systems (FACTS) instruments, the unpredicted interactions have been increased in the power system. Thus, the designing and setting of proper controllers is crucial for the improvement of the dynamic response of a power system along with the FACTS instruments. Because of that in this paper, a new optimization algorithm-based method of Fuzzy Adaptive Bacterial Foraging (FABF) has been used to design the Power System Stabilizer (PSS) and the Thyrist or Controlled Series Capacitor (TCSC) for damping the low frequency oscillations of the power system. The aim of this design is to minimize the deviation of speed and generators terminal voltage in a great range of loads with the use of FABF algorithm. Designing of TCSC and PSS has been both independently and simultaneously performed to confirm the discussed method. The comparison of this method with the Particle Swarm Optimization algorithm (PSO) in the4-machine Kundur system and the10-machine New England system, shows the superiority potential of this method.

“…In this respect, flexible AC transmission systems (FACTS) technology has been proposed to provide the actual capacity without the requirement of new transmission lines or reconfiguration [1]. The thyristor-controlled series capacitor (TCSC), as a significant member of the FACTS family, has been applied to solve diverse problems, such as scheduling fast power flow, limiting short-circuit currents, regulating continuous reactance, mitigating subsynchronous resonance (SSR), damping the power oscillation, or enhancing transient stability [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”

“…The simulation results in [14] showed that a network with a TCSC using an FLC had a better response compared to a PID controller. In [15][16][17]19], several fuzzy TCSC damping controllers were designed and investigated to improve power system stability.…”

Nowadays, the use of flexible AC transmission systems (FACTS) is an economical and interesting approach to improve power transfer capability. The thyristor-controlled series capacitor, as a member of the FACTS family, can control interrelated parameters with dynamism due to its ability of rapid control and stabilization. Regardless of all of the works in this area, the control of transmitted power through the design of the firing angle controller is still missing. In this paper, first, the open-loop firing angle controller and its sensitivities are analyzed to fill in this gap. Next, closed-loop controllers such as PID and fuzzy controllers are designed and simulated in MATLAB/Simulink software. Simulation results show that the fuzzy logic controller has a better response, although it is designed with minimum, simple, triangle membership functions and reduced rule bases.

“…Therefore, capabilities of traditional control laws based on linearized models are limited. To address this problem, FACTS control using fuzzy control scheme has been proposed [7], [15], [16]. Unlike previous control configurations, this paper proposes a fuzzy lead-lag control scheme for the control and coordination of TCSC and SVC devices in a multi-machine PS.…”

This paper proposes an evolutionary fuzzy lead-lag control approach for coordinated control of flexible AC transmission system (FACTS) devices in a multi-machine power system. The FACTS devices used are a thyristor-controlled series capacitor (TCSC) and a static var compensator (SVC), both of which are equipped with a fuzzy lead-lag controller to improve power system dynamic stability. The fuzzy lead-lag controller uses a fuzzy controller (FC) to adaptively determine the parameters of two lead-lag controllers at each control step according to the deviations of generator rotor speeds. This paper proposes an Advanced Continuous Ant Colony Optimization (ACACO) algorithm to optimize all of the free parameters in the FC, which avoids the time-consuming task of parameter selection by human experts. The effectiveness and efficiency of the proposed evolutionary fuzzy lead-lag controller for oscillation damping control is verified through control of a multi-machine power system and comparisons with other lead-lag controllers and various population-based optimization algorithms.Index Terms-Ant colony optimization, flexible AC transmission system (FACTS), fuzzy control, static var compensator (SVC), swarm intelligence, thyristor controlled series capacitor (TCSC).
