Improving Voltage Stability of Electrical Power System by Optimal Location of FACTS Devices Using an Evolutionary Method

Abstract

In the present work, a new approach for improving voltage stability by optimal location of the Flexible AC Transmission Systems (FACTS) devices has been discussed. We used Genetic Algorithm (GA) as an optimization technique to search the good placements of different FACTS systems in great electrical networks and its contribution to enhance voltage stability. Various FACTS devices were used in our study such as SVC, TCSC, SSSC, STATCOM, TCVR, TCPST and UPFC. The search of optimal parameters of those devices has been also investigated. The method presented in the paper was tested by using Matlab/environment. In addition, the proposed method has been implemented and tested on various IEEE power systems; 14Bus, 57Bus, and 118Bus. The obtained results show the validity of the proposed method.

“…In the real number space, each discrete possible solution can be modeled as a particle that navigates through the problem hyperspace. The position of each particle is determined by the vector and its movement by the velocity of the particle , as shown in (1).…”

“…Optimal placement of this technology can reduce overloading and improve voltage stability in the electrical network. The problem of voltage stability is mainly caused by overloading condition of the system [1].…”

“…Several techniques have been proposed by many authors to reduce stress loading and improve voltage stability of the existing power systems. In heuristics methods based on genetics was used to determine the optimal locations of FACTS devices in the electrical network to improve stress loading and voltage stability [2]. This was validated on standard 14-node IEEE network in the MATLAB environment.…”

Optimal UPFC Placement for Voltage Stability Enhancement

“…16 Lemdani et al, (2019) suggested a genetic based stochastic strategy for placing FACTS devices in power networks besides studying the significances on system performances. 17 Dawn et al, (2018) used two indices for finding the best buses and parameters for FACTS and wind farm placement for reducing the economic risks in deregulated environment. 18 Rambabu et al, (2019) studied several indices for assessing the health of the systems under contingent conditions, and suggested a grey-wolf optimization-based method involving a composite bus utilization index for placing static voltage compensators on systems with wind and solar power plants.…”
