چکیده
A new formulation of bi-objective optimization for the general capacitor placement and sizing problem is presented. The objectives include energy loss reduction, investment cost minimization, and maximum voltage deviation improvement. The operating and expansion constraints of the system are considered for practical needed. Also, both fixed and switched types of capacitors are included. A particle swarm optimization aided interactive best-compromise method for solving general bi-objective optimization problems is then proposed. It can provide a flexible solution as dictated by the decision makers of the utilities. To demonstrate the effectiveness of the proposed method, comparative study is conducted on an actual feeder with rather encouraging results. Key-Words: Capacitor placement, sizing problem, Bi-objective programming, Distribution feeder, Interactive bestcompromise, Particle Swarm Optimization.
