Abstract

Congestion management is one of the most important issues for secure and reliable system operations in deregulated electricity market. Rescheduling the real power output of generators in the system is the most practiced technique for congestion management. In this research, multiple distributed generators are connected optimally along with above said conventional method to alleviate congestion. Particle Swarm Optimization (PSO) is used to determine the optimal generation levels and for finding the optimal sizes of multiple DGs, both PSO and GA are used to alleviate transmission congestion. Numerical results on modified IEEE 30 bus system is experimented for illustration. The complete experimental outcomes demonstrate that the PSO is one among the demanding optimization methods for this proposed problem than GA.
