Abstract
Power quality has been gaining importance in the last few years and, more so, because of the deregulation of electricity. Harmonic distortion at a load bus is of paramount importance to both utility and customers. For the utility, a power factor (PF) improvement reduces system losses and increases the portion of generation capacity available for productive uses. This letter introduces a mathematical model to select the size of a compensating capacitor with minimum total cost including limitation of the PF, avoiding resonance condition, and satisfying the IEEE Std 18-1992 limits.
