Application of DE & PSO Algorithm For The Placement of FACTS Devices For Economic Operation of a Power System
Authors: B. Bhattacharyya, Vikash Kumar Gupta, S. K. Goswami
Abstract: In this paper, use of Differential Evolution (DE) based and Particle swarm optimization (PSO) based algorithm for the allocation & coordinated operation of multiple FACTS (Flexible AC Transmission System) devices for the improved power transfer capacity and economic operation of an interconnected power system is presented. Both the DE and PSO based approach is applied on IEEE 30-bus system. The system is reactively loaded starting from base to 200 % of base load and the system performance is observed with and without FACTS devices. Active and reactive power flow in different lines gives an idea in determining the positions of FACTS devices to be placed in the system for the improved performance. Then the DE & PSO based optimization approach is applied to find the size of the FACTS devices and the comparative analysis between these two techniques are made. This differential evolution (DE) based approach for the installation of FACTS devices found as more beneficial than PSO based method.
