Transmission Capability

Distributed Flexible Alternating Current Transmission System (DFACTS) devices are devices that are connected in series to the transmission line and even adding reactance. Devices, also referred to as Distributed Serial Reactors (DSR), have the ability correct impedance imbalance by interfering with line parameters in the power system. In addition, voltage balancing as a result of balanced load flow enables more power transmission or more efficient use of the power system's transmission capability. For this reason, the use of the system to control its loadability without expanding its dimensions is becoming more and more widespread. In this study, the effects of DSR devices on system loadability and voltage stability and their applicability are analyzed. The analysis was carried out on the Institute of Electrical and Electronics Engineers (IEEE) 6-bus Standard system using the Power World Simulator Program. The effects of DSR on the system were investigated by performing load flow.

The Stability

The Flexible Alternating Current Transmission Systems (FACTS) device deals with the control of power flow, alternating current of transmission line and immediately respond towards the stability problems of the system. The present paper show that how the FACTS devices enhance the different parameter of the power systems like power transfer capacity of line, system stability etc. In MATLAB a simplified transmission system is modeled and the resultant power (PQ) and voltage profiles are studied as an uncompensated system. Now the same transmission system is simulating with FACTS device i.e. Static Synchronous Series Compensator (SSSC), Fixed Capacitor Thyristor Controlled Reactor (FC-TCR) and Static Synchronous Compensator (STATCOM). The result obtained after simulation provide the power and voltage profiles, are analyzed as a compensated system. Finally we found that a compensated system have better voltage profile and power flow w.r.t. an uncompensated system.

This research aims to improve the steady-state performance of high-voltage power transmission lines, which is a significant challenge for the power system grid's safe and reliable operation. The research adopted Flexible Alternating Current Transmission System for electronic devices. The flexible alternating current transmission system technology will be used in this specific work as Thyristor-Controlled Series Compensators. Thyristor-controlled series compensator devices increase transmission systems' capacity and enhance the voltage profile by regulating transmission line reactance. Gravitational Search Algorithm is a meta-heuristic approach applied to find the optimum size and optimal location of thyristor-controlled series compensators in power systems. The gravitational search algorithm is used to solve the multi-objective and integrated optimum power flow problem in reactive energy management during normal and contingency operations. The results showed reduced voltage deviation, reduced active/reactive power losses, and increased transmission line reserves above thermal limits, in addition to reducing the installed cost and number of thyristor series compensators devices. The simulation part was created with MATLAB programming language and validated with MATPOWER software. Applied to IEEE 30 bus system and 400kV super high voltage grid system.
