Congestion Management in Power System—A Review

Abstract

Power system deregulation created a significant impact in power system network. Though power system deregulation has advantage, it adversely affects the network congestion. Congestion mainly occurs due to failure of transmission utility to transmit the power based on the load demand. So, there is a need of congestion management techniques. Different congestion management techniques are reviewed in this paper which includes generator rescheduling, load shedding, nodal pricing technique, optimal location of diesel generator and some of the cost-free algorithms genetic algorithm, particle swarm optimization, shuffled frog algorithm, mixed integer nonlinear programming, and approaches corresponding to fuzzy logic. This paper reviews the publications of various works to evaluate the importance of every technique in mitigating congestion of transmission network.
