Probabilistic Model for Residential Load Profiles and Power Quality Improvement

20 Jul 2016

The use of domestic renewable energy, modern appliances and electronic gadgets at home are becoming more popular as technology develops. This paper investigates the electricity requirements of these appliances and their influence on power quality (PQ). PQ issues vary from device to device depending on applications in the residential, commercial and industrial sectors. PQ problems are very challenging in electrical distribution systems. A literature survey was done on existing models of residential loads affecting PQ. The residential loads investigated in this paper are domestically used photo voltaic (PV) roof top systems and small wind turbines. This paper further focuses on voltage unbalance due to rooftop PV in residential areas and factors which affect wind turbine flickers.
