EXCELLENT ALLOCATION OF CAPACITORS IN SYSTEMS OF RADIAL DISTRIBUTION, USING EVOLUTION STRATEGIES

by Petinelli, Airton Egydio

Abstract (Summary)
Static reactive power sources, such as shunt capacitors, have been commonly used toprovide reactive compensation in distribution systems, minimizing losses and keeping voltagelevels within operational limits. Heuristic algorithms for capacitor placement have beenproposed in several works. However, the majority of these approaches converge to a localsolution.This dissertation presents a hierarchical evolution strategy-based approach for solvingthe optimal reactive sources placement in radial distribution systems. The approach is basedon the (m+l)-EE paradigm, improved by mutations control and by two types of mutations: theclassical Gaussian mutation and the Cauchy-based mutation.Discrete standard capacitor values with non-linear cost are considered. Constraintssuch as the maximum number of parallel banks and installations cost are included. Validationtests have been performed using a real industrial feeder.
