It is obvious that power quality is an important characteristic of today's distribution power systems as loadsbecome more sensitive on the other hand nonlinear loads are increasing in the electrical distribution system.Considering the distributed nature of harmonic loads, the need for distributed power quality improvement (PQI)is inevitable. From years ago, researchers have been working on various kinds of filters and devices to enhancethe overall power quality of power system, but today the nature of distribution system has been changed andpower electronic based DGs play an important role in distribution grids. In this paper, a thorough survey is doneon power quality enhancement devices with emphasis on ancillary services of multi-functional DGs. A literaturereview is also done on microgrids concept, testbeds and related control methods. Although there were someapplications of DGs for PQI improvement these applications were not defined multi-functional DGs. Variouscontrol methods are studied and categorized regarding different viewpoints in the literature. Finally, a couple ofthorough comparisons are done between the available techniques considering the nature, capabilities, advantagesand implementation costs.
