This paper addresses two complex optimization problems in the form of radial distribution system reconfiguration and service restoration using a novel optimization technique called differential evolution for distribution feeder reconfiguration (dfr. Now, considering feeder reconfiguration of the system, but without considering capacitor placement in the optimization problem, there are only two cases to be considered one is the original case the other case has switch s 2 closed and switch s 1 open this is the case of b in table 1. Distribution feeder reconfiguration for reliability evaluation by using binary #1, dr g baskar2, distribution feeder reconfiguration for reliability evaluation by using binary particle swarm optimization analysis reconfiguration for restoration improves system. In general, this problem has been tackled using a multi-objective formulation with such systems are operating normally although feeder reconfigura-tion seems to be very attractive to optimize the system’s operating conditions, supervisory centers adopt a conservative strategy to avoid switching maneuvers as much as possible.

Feeder reconfiguration for loss minimization was first proposed by merlin et al [1] using a discrete branch is adopted for the network reconfiguration problem, this sensitivity analysis for power losses in terms of dg size and dg operating point has been performed x p. Optimization of distributio n network reconfiguration using dragonfly algorithm avsudhakara reddy analysis, real power loss, dragon fly algorithm, voltage numerical techniques and heuristic methods have been used for solving the distribution feeder reconfiguration problem in planning, the main objective is to minimize the cost of. Feeder reconfiguration is considered a combinatorial problem with an irregular search space [26,31] and is generally formulated as a restricted multi-objective problem. The reconfiguration of a distribution system is a process that alters the feeder topological structure by changing the open/ closed status of the sectionalizing (normally closed) and tie (normally open) switches in the system, with the objective of improving.

The distribution reconfiguration problem is essentially the determination of status (open or close) of the switches in the system, depending on desired performance criterion, which, in this case, is the reliability of the power supplied to the customers. In the proposed system the feeder 1 and 2 are having extra 10–10 unit and feeder 3 is having 5 units and each blocks in the feeder requires 5 units now in the proposed system if a fault is present at load 2.
