It is well known that a major portion of power system losses occur at the distribution level. Some of these losses can be eliminated by proper selection of shunt capacitors on primary feeders via power factor correction. The objective of this paper is to present an algorithm for optimizing shunt capacitor sizes on radial distribution lines with nonsinusoidal substation voltages, such that the rms voltages and their corresponding total harmonic distortion lie within prescribed values. The problem is formulated as a combinatorial optimization problem with inequality constraints. A simple heuristic numerical algorithm that is based on the method of local variations is proposed to determine an optimal solution. An example shows that optimal capacitor sizes found by neglecting the harmonic components may result in unacceptable voltage distortion levels.
