Reactive power control and power loss minimization in electrical network by using facts devices

Abstract

The increase in power requirements causes the wide expansion and development of power systems, resulting in high demand in power systems. The most common power system problems are uncontrolled reactive power and power loss during transmission and distribution; thus, electricity almost requires a network for transmission and distribution to the customers. The FACTS devices are useful for increasing the efficiency of power system, power factor improvement and harmonic reduction. The reactive power is used to regulate the voltage levels in the transmission system and to improve the efficiency of system on various busbars. The electrical network benefits greatly from reduced reactive power, energy losses and voltage in accepted limits. This project will use a proper FACTS device controller to regulate reactive power and voltage profile, allowing it to provide active and reactive regulation to achieve transmission line loss minimization, real power transfer at maximum, system stability, voltage profile improvement. The effects of reactive power have been discussed, the total losses reduced from 5% to 0.5% and reactive power were controlled in this work with different techniques by using capacitor banks and static VAR compensators, Thyristor controlled reactor (TCR), SSS, STATCOM and Unified power flow controller (UPF) were simulated by using MATLAB/SIMULINK software version 2017b.
