On the Economic Selection of Capacitive Compensator Sizes in Nonsinusoidal Conditions

The selection of the optimal capacitor is a multiobjective op- timization problem. An approach to solving a multiobjective optimization problem is to transform it into a single objective problem. In this letter the use of the power factor and the efficiency as constraints is proposed be- cause power factor in distributions systems may be allowed within certain limits such as 0.85 and 1.0 and similarly for the efficiency. Keywords: Harmonics, power factor, power quality. Introduction: Reference (1) discussed the different criteria for the design of the compensating capacitor for the system shown in Figure 1, taking into consideration the skin effect (a) Maximizing the power factor,
