FACTS Devices Injection in Electrical Network for Reactive Power Compensation

Abstract

With the growth of urban and rural infrastructure, the power system is pushed to run near capacity, resulting in overloaded power grids, higher losses, peak generation, security threats, and network instability. The performance of the legacy electric network may be improved by supplying sufficient reactive power through grid voltage tuning, transformer tap setting, capacitor bank sizing, and the use of computational intelligence technologies. Voltage control, power factor enhancement, and voltage supply have become simple with these power electronic devices. These FACTS devices outperform the previous cumbersome equipment employed for the same purpose. FACTS controllers with harmonic filters are the best solution to improve supply voltage. In this vein, this article offers a thorough bibliography of different FACTS devices intended to improve power system performance by compensating reactive power. Finally, novel FACTS device combinations are proposed to magnify power system current and voltage. This study will be immensely beneficial to researchers for fast reference on the FACTS controllers.
