Genetic based algorithm for active power filter allocation and sizing

Active power filters (APF) can be employed for harmonic compensation in power systems. In this paper two algorithms are proposed for optimum allocation and sizing of APFs. In the first algorithm, the aim is to minimize the voltage harmonic distortion while in the second; the aim is to meet the harmonic standard levels by minimum injection of APF currents. Both algorithms are solved using genetic algorithm (GA) as the optimization tool. The performance of the proposed approaches are assessed and appreciated by various case studies on an 18-bus test system. [Copyright &y& Elsevier]
