ENHANCEMENT OF VOLTAGE STABILITY IN RADIAL ISTRIBUTION SYSTEMS THROOGH ONLINE NETWORK RECONFIGURATION USING GENETIC ALGORITHM

摘要

Network reconfiguration of distribution system is an operation to alter the topological structure of feeders by changing open/closed status of sectional/zing and tie switches. Network reconfiguration for time varying loads is very complex and extremely non-linear optimization, which can be effectively solved using Genetic Algorithm (GA). By reconfiguring the network, voltage stability can be improved in distribution systems. In this paper a method is proposed for the enhancement of voltage stabilityunder varying load conditions by online network reconfiguration using GA. This method is computationally efficient and in general gives conservative estimates of voltage stability. The proposed method is tested on 16-node and 33-node radial distributionsystems.
