Power quality general levels in distribution networks

This paper has focused on power quality investigation based on complex measurements in the substations of local distribution networks. The distribution network area chosen for the present analysis is of interest for a further renewable sources connection. For the power quality assessment a new type of information report is discussed as viable future alternative for network operator. According to this, the phenomena are evaluated and displayed in a unitary manner by using the ranking of power quality level based on normalized parameters. PQ disturbances maps can be drawn by using this condensed information format.
