Optimal Design of Multitype DG Resources Using Particle Swarm Optimization

G.P.Amisha Vishnu Priya, Dr.S.Kalyani

Increased interest in application of green technology and shortage of distributed current carrying capabilities has led to use of Distributed Generation (DG) Systems. The estimated use of DG in the future requires the distribution system engineers to properly take into account its impact in the system planning. Hence, optimal location and sizing of DG in distribution networks is drawing much attention in electric power utilities. Optimal allocation of different types of renewable DG units in the distribution system is used to minimize energy loss. Proper location of DG units in power systems is used to maximize the potential benefits and reduce impact on the power system. Heuristic optimization techniques like Particle Swarm Optimization (PSO), is used as a solver tool to minimize the power loss by changing sitting and varying sizes of DG. The simulation will be carried out on standard rural distribution networks viz, 15-bus and 69-bus distribution systems.
