Disaster management of distribution line using fixed and switched capacitors

Abstract

This papers proposes a plan of using fixed and switched capacitor for the during disaster condition of distribution system. The configuration of a distribution network is different from a transmission network. Distribution systems are typically radial: the loop power flow does not exist. Distribution systems include the inductive loads along with transformers and lines, which account for quite significant power loss due to lagging current. The introduction of strategically sized and placed shunt capacitors within the distribution system help to counteract the losses created due to an inductive system by, increasing the system capacity, reducing system losses and improving the voltage profile. The problem of capacitor allocation includes the location, type (fixed or switched), and size of capacitor. The sizing of capacitor is determined by a simple capacitor-sizing algorithm developed in MATLAB.
