Transmission congestion management considering voltage stability margin

Abstract This paper presents a solution for the transmission congestion management considering voltage stability issues using optimal generation rescheduling. While practicing optimization techniques, control variables remain under their upper or lower limits but it may lead to lowered level of security after optimization. To counterbalance this adverse effect, modified objective function has been used. The reactive power rescheduling and support from capacitors have incorporated along with active manage as well improve network margin. Random Inertia Weight Particle Swarm Optimization (RANDIW-PSO) algorithm employed in obtain optimized solutions. proposed methodology is tested on New-England test system different realistic scenarios. results confirm noteworthy decline cost improvement Moreover, performance improved terms losses, increased reserve at generators profile.
