An advanced control algorithm for Series hybrid active filter adopting UPQC behavior

This paper presents an advanced comprehensive control approach for Hybrid Series Active Filter (HSeAF). This configuration consists of a series active filter (SeAF) and a shunt passive filter. The proposed control strategy, make this topology capable of compensate current distortions at the source and voltage harmonics and related issues from the load point of common coupling (PCC). The controller compels the HSeAF to perform as Unified power quality conditioner (UPQC) with similar behavior. The control algorithm employs the synchronous reference frames and the p-q theory to create an advanced controller for HSeAFs. This proposed algorithm treats diverse power quality issues simultaneously. With a fast and accurate response, it makes the PCC more reliable, cleans the power system from any current distortions, and also corrects the power factor. Hence, in this paper, the proposed control approach is studied and analyzed by simulations.
