Network Reconfiguration for Loss Minimization by Optimal Switching Operation in Distribution System

There are three functional areas of electrical utility namely Generation, Transmission and Distribution. Out of three functional areas of Electrical utility, the distribution sector needs more attentions and difficult to standardize due to its complexity. Aggregated Technical & Commercial (AT&C) Loss i.e. T&D loss in India has been consistently on the higher in the range of 28-30 pre cents. Out of these losses major share are at Distribution level. This is due to inadequate investments for system improvement works. In this paper to reduce the technical losses and analysis is carried out for the distribution network on the measurement of unbalanced current, reactive power, active power, and voltage profile of every network in distribution feeders using MAT LAB software and results are simulated.
