Optimal energy loss estimation by locating and sizing capacitors in radial distribution system using fuzzy and optimization techniques

Abstract

A distribution system is an interface between the bulk power newlinesystem and the consumers Among these systems radial distribution systems newlineare popular because of low cost and simple design In distribution systems newlinethe voltages at buses reduce when moved away from the substation and also newlinethe losses incurred are high The reason for decrease in voltage and high newlinelosses is the insufficient amount of reactive power which can be provided by newlinethe shunt capacitors newlineIn the radial distribution system capacitors are installed at suitable newlinelocations for the improvement of voltage profile and to decrease the energy newlineloss It is estimated that as much as 13 of total power generation is newlinedissipated as I2R losses in the distribution networks Reactive currents newlineflowing in the network constitute for a portion of these losses By the newlineinstallation of shunt capacitors the losses produced by reactive currents can newlinebe reduced newline newline
