Improving Voltage Stability of Power System by Optimal Location of FACTS Devices Using Bio-Inspired Algorithms

Abstract

Power system operations can be optimized using power electronics based FACTS devices. The location of these devices at appropriate transmission line plays a major role in their performance. In this paper, two bio-inspired algorithms are used to optimally locate two FACTS devices: UPFC and STATCOM, so as to reduce the voltage collapse and real power losses. Particle swarm optimization and BAT algorithms are chosen as their behaviour is similar. VCPI index is used as a metric to calculate the voltage collapse scenario of the power system. The algorithm is tested on two benchmark power systems: IEEE 118 and the Indian UPSEB 75 bus system. Performance metrics are compared with the system without FACTS devices. Application of PSO and BAT algorithms to optimally locate the FACTS devices reduces the VCPI index and real power losses in the system.

A Comprehensive Review on Optimal Location and Sizing of Reactive Power Compensation Using Hybrid-Based Approaches for Power Loss Reduction, Voltage Stability Improvement, Voltage Profile Enhancement and Loadability Enhancement

“…In [135], the optimal location of FACT devices was proposed using the two similar behavior of bio-inspired algorithms, namely, PSO and BAT algorithm that aimed to reduce the voltage collapse and real power losses. UPFC and STATCOM were considered in this study since UPFC is one of the most popular FACTS device that is capable to operate under system insecurity while STATCOM is capable to operate under various stress conditions.…”

“…Another method to improve voltage stability in EN system, by optimal location of FACTS, has been published by Naganathan and Ranganathan. In the cited research papers, the use of the PSO algorithm as an optimization technique aims to determine a suitable position of STATCOM and UPFC in order to improve voltage stability in IEEE 118Bus and 75Bus power system [3].…”
