An Overview on Power Quality Issues and Control Strategies for Distribution Networks With the Presence of Distributed Generation Resources

Power systems based on centralized production are facing two limitations: the lack of fossil fuels and need to reduce pollution; Therefore, importance distributed generation resources (DGs) has increased by connecting renewable energy network. With increasing penetration energies in network, power quality challenges low voltage medium distribution have become one main fields studies. Since most connected network with help electronic converters devices purpose these is connect DGs compliance standards; if switching frequency inverters not implemented properly, major problems will be created. On other hand, reduction causes acute networks, which include proper performance, useful life efficiency electrical creation series parallel resonance some harmonics due presence inductors capacitor, as a result, more distortion This paper actually provides road-map for researchers investigate issues. In words, mentioned cases show research providing solutions improving networks.
