In modern power systems, FACTS tools are essential for addressing voltage variation along with fault ride-through (FRT) challenges within the electrical power systems, particularly for wind generation integration. Several prominent publications emphasize that the squirrel cage induction generator (SCIG) currently comprises about 15% of operational wind turbines. This research proposes the use of FACTS devices to boost voltage stability and FRT capability. The implementation of these devices leads to improved efficiency in the electrical power system. This study considers many events, including an ideal wind profile, turbulent wind profile, symmetrical faults, and unsymmetrical faults, to support the proposed selection. Furthermore, the proposed approach is evaluated by comparison between a fixed capacitor, static synchronous compensator (STATCOM), and Static VAR Compensator (SVC) to guarantee the achievement of voltage stability, reactive power consumption, and FRT capacity under various wind speed profiles and fault conditions. An overall evaluation is conducted to compare them in all examined circumstances and to highlight their advantages and effects. The simulation findings demonstrate the efficacy and primacy of FACTS in enhancing the functioning of an integrated wind system, which is built upon a grid-connected SCIG, as well as enhancing the power system performance. The MATLAB/Simulink toolbox is used to design the models of SCIG, SVC, and STATCOM.

As we all know that most of the power systems are interconnected through long distance tie lines, in order to transfer a large amount of electric power. There are some constraints which affect to build new transmission lines, which are: limited availability of resources, strict environment and shortage of funds. Because of these constraints it necessitates the operation of transmission lines near or for short term on their thermal loading limits. Day by day the demand in electric power rapidly increases and is expected to continue growing; while growth of generation is restricted too, due to the same constraints mentioned above, this necessitates the generators to operate near their maximum stability limits. As a result of all these factors, power systems oscillations occurs and if not damped out these oscillations, the magnitude of these oscillations will go on increasing until loss of the system synchronism. So, for the improvement of power transfer capability within the safe stability limit it is necessary to enhance the transient stability of the power system. The objective of this paper is to investigate the enhancement of transient stability on power system by different types of power system stabilizers, which are: (I) Speed Input (II) Power Input (III) Frequency Input (IV) Del-P-Omega (V) Combination of frequency-electrical power input PSS and (VI) Speed-electrical power input PSS.

Series compensation in transmission line with fixed series capacitor may cause Subsynchronous Resonance (SSR) at certain compensation level. This paper presents the application of static synchronous series compensator (SSSC) to mitigate impact of SSR. For analysis of SSR, IEEE first benchmark model is used and SSSC is located in transmission line at generator end. The linearized state space equation of SMIB system without and with SSSC has been developed to carry out eigenvalue analysis to identify potential modes for SSR. The AVR and PSS in the generator control loop coordinated with SSSC can successfully mitigate SSR. Time domain simulation is also carried out to confirm the results obtained with eigenvalue analysis.

This paper is aimed at giving an optimized method of laying out Thyristor-Controlled Series Capacitors (TCSCs) in power systems with reference to the IEEE 14-bus, 33-bus, and 57-bus test systems. The desired outcome is to improve the voltage stability, and power losses. TCSC placement and sizing is optimized with the type of a new hybrid algorithm that is a composite of Blue Whale Optimization (BWO) algorithm and Salp Swarm Optimization (SSO). Performance of the system is assessed with and without TCSC placement based on active and reactive power loss minimization, voltage profile enhanced and use of TCSC. The findings illustrate that the hybrid BWO-SSO algorithm is good in improving the stability, loss, and voltage regulation in the test systems, which may give insight in the usage of TCSC in the contemporary power systems.
