Efficient Utilization of the Power Grid using FACTS devices based on a new Metaheuristic Optimizer

FACTS controllers can boost the effectiveness of power systems by continuously controlling the power system parameters. This work presented the allocation of Flexible Alternating Current Transmission Systems (FACTS) devices based on a new algorithm called the Improved Gray Wolf optimizing Method (IGWO). The proposed approach introduces the various FACTS controllers’ optimum location and size to mitigate the real power losses, bus voltage deviations, and system operating costs. The thyristor-Controlled Series Compensator (TCSC), Static Var Compensator (SVC), and Unified Power Flow (UPFC) devices have been used as FACTS devices. A comparative study was performed with other heuristic optimization algorithms, such as Grey Wolf optimizer (GWO) and Simulated Annealing (SA) algorithms, to verify the suggested algorithm’s effectiveness. Computer simulation has been applied to the IEEE 30 bus system. Conversion curves and detailed numerical simulation results have shown that the IGWO technique is superior to the comparative algorithms.
