Optimal Capacitor Placement in Distribution Feeders

Authors: N. Rugthaicharoencheep, S. Auchariyamet


Optimal capacitor allocation in distribution systems has been studied for a long times. It is an optimization problem which has an objective to define the optimal sizes and locations of capacitors to be installed. In this works, an overview of capacitor placement problem in distribution systems is briefly introduced. The objective functions and constraints of the problem are listed and the methodologies for solving the problem are summarized.

Keywords: Distribution Systems, Optimization Techniques, capacitor placement
