Optimal Placement of Hybrid Active Power Filter

Selecting the optimal placement of hybrid active power filter in power distribution system was discussed. The simplified models of power distribution system and hybrid active power filter were built up, and then the network objective function (NOF) of harmonic elimination was defined. A numerical analysis based on analytical formulation that used the power distribution system voltage and current transfer matrices was derived providing a user a friendly and general tool to determine the most adequate point of system connection of hybrid active power filter, for improving the compensation effectiveness. The influence of variety of the grid parameters was discussed. Moreover, the proposed method allows the technical evaluation of the harmonic elimination and reactive power compensation in a power distribution system, and the validity of the developed method is verified by the experimental results.
