In electrical distribution systems, a great amount of power are wasting across the lines, also nowadays power factors, voltage profiles and total harmonic distortions (THDs) of most loads are not as would be desired, So these important parameters of a system play highly important role in wasting money and energy, and besides both consumers and sources are suffering from a high rate of distortions and even instabilities. Active power filters (APFs) are innovative ideas for solving of this adversity which have recently used instantaneous reactive power theory. In this paper, a novel method is proposed to optimize the allocation of A PFs. The introducod method is based on the instantaneous reactive power theory in vectorial representation, use of this representation, it is possible to asses different compensation strategies. Also, A Pfis proper placement in the system plays a crucial role in either reducing the losses costs and power quality improvement. To optimize the APF%26apos;s placement, a new objective function has been defined on the basis of five terms: total losses, power factor, voltage profile, THD) and cost, Genetic algorithm has been used to solve the optimization problem. The results of applying; this method to a distribution network illustrate the method advantages.
