摘要：
In this paper, a new scheme of recloser-fuse coordination for reconfigurable radial distribution networks (RDNs) considering distributed generations (DGs) is introduced. Further, a new graph theory based approach has been developed to obtain all possible topologies in RDNs. Also, a new constraint reduction strategy has been introduced to eliminate a large number of constraints in the formulation because of the consideration of various topologies. To solve the formulated optimum recloser-fuse coordination problem, an analytical interior-point method has been adopted. The developed strategy has been applied to obtain the optimum recloser-fuse settings in the IEEE 33 and 69 bus reconfigurable RDNs in the presence of DGs. The obtained settings have been compared with conventional recloser-fuse settings thereby proving the effectiveness of the presented scheme.
