Abstract

This manuscript proposes a novel technique to solve the feeder reconfiguration problem with an objective of minimizing total real loss and maximizing energy savings in a radial distribution system. Feeder reconfiguration (FRCG) is a significant way of altering the power flows through the lines or to alleviate the overloads on the feeders, while maintaining the radial structure. To ensure the radial nature and avoid islanding of nodes, all feasible switching combinations are formed prior to the optimization process using a graph theory. This FRCG problem enables for determining the best combination of switches are to be opened for maximum loss reduction and energy savings, so it offers optimal performance. A Meta-heuristic Whale Optimization (WOA) Algorithm is used to reconfigure and identify the optimal secure switches for maximum real power loss reduction, which directs to energy savings in the main distribution system. The constraint of real power loss is incorporated into the estimation of the objective function. The anticipated method has been examined on standard 33-node and 119-node systems at regular load pattern, where attained results are compared by means of available literature.
