Abstract
The selection of an adequate number of switches and their location is a difficult
task in distribution system planning. However, distribution feeder sectionalization I
plays a key role in reliability enhancement, phase balancing, los~ reduction, and I
automation of power distribution systems. The problem of placement of
sectionalizing switches in radial distribution systems (RDS) falls into the class of
discrete variable optimization problem with single minimum.
This research presents the use of simulated annealing (SA) search algorithm in
conjunction with previously published general-search technique to determine the
optimal number and location of sectionalizing switches in RDSs based on technoeconomical
feasibility maximization. The problem formulation takes into account
reliability, investment, and maintenance costs.
Optimal placement of sectionalizing switches is determined in a variety of
distribution systems. Using SA for determination of optimal number and location
of sectionalizing switches greatly reduces the number of candidate locations of the
sectionalizing switches with respect to the standalone general search technique.
The research shows that the combined SA-general search technique offers an
accurate method for placement of sectionalizing switches in distribution systems.
