Synopsis

Power systems are widely interconnected across regions for economic reasons, to reduce the cost of electricity and improve the reliability of power supply. The rapid development of semiconductor technology in Power Electronics has revolutionized the art of power modulation which opened up new ways in which, power control can be achieved for both and high-voltage and low-voltage transmission and distribution systems. Power systems may also lead to insecurity, with growing technological advancements impacting the power industry. Bottlenecks in interconnected power systems that may lead to security problems might include excessive reactive power, faults, dynamic swings of connected loads, and generation capacity. Hence voltage stability analysis plays a key role in Electric Power System and maintaining a stable and secure operation of a power system is very important and challenging issue.

The affects of harmonic generating equipment, coupled with system resonance condition are cumulative and can be severe on system operations, if not mitigated. Hence, to provide dynamic control of system voltage, frequency, and reactive power, and to design the generation capacity and decide upon the rating of protective devices, will be of significant use to avoid outages and increase the reliability of power systems.

The essence of the proposed system is to minimize the voltage fluctuations and intermittent problems by using Power Electronics that seems to be viable option for efficient Power System. Reduction of system loses is of paramount importance because of its financial, economic and socio economic values to the utility company, customers and the host country. Penetration of FACTS based devices in electric system can be used to overcome all power losses and voltage instability problems. The implemented of this system not only prevents economic losses due to the destruction or shortening of useful life of the equipment, but also increases the quality of energy supply to customers by enhancing the voltage profile at buses there by reducing the power losses considerably. Optimal placement of FACTS devices, in suitable location of Power network will improve the power transmission and distribution capability, by maintaining a stable and secure operation and ensures the quality of whole power grid system to the end utility.
