Abstract:
Electrical power systems, which are controlled by electrical and mechanical systems, are critical components of modern society. Economic dispatch is a critical process in the operation of a power system that aims to allocate power generation to match load demand at the lowest possible cost while satisfying all generators and system constraints. The increasing use newlineof sensitive equipment in modern power systems necessitates a strong emphasis on power newlinequality. Quality issues such as voltage sags, swells, surges, interruptions, and harmonic newlineproblems cause significant economic loss in the power industry and necessitate immediate newlineaction. FACTS (Flexible Alternating Current Transmission Systems) can manipulate and newlineimprove the fundamental components of an electrical system used in conveyance to ensure the newlinereliable and stable operation of the power system. The FACTS device solves critical issues such newlineas voltage stability, line overloading, power loss, power flow, and so on. The FACTS device is newlineimportant in improving power system operations, whether static or dynamic, and requires a newlinecapital investment. As a result, the FACTS device can be optimized in terms of position and size to improve the performance of the power system. In the power system, four different FACTS devices such as series, shunt, combine series and shunt, combine shunt and series newlinedevices are selected to place in suitable locations to raise the voltage level and reduce power losses. The effects of FACTS devices on various bus network parameters such as generation cost, power loss, and voltage stability, among others, are assessed. To reduce power loss and maintain a voltage level, the FACTS devicesand#39; size and location must be improved. Voltage instability has recently been identified as a critical issue in the transmission line system due to its dynamic load pattern and increasing load demand. Flexible AC Transmission Systems newline(FACTS) devices are used to reduce voltage instabilities by controlling real and reactive power via the transmission line system.
