Power Quality Indices of Distribution Networks with Embedded Generation

Abstract

The present paper deals with the relevant aspects related to EG and its influence on the quality of supply of the distribution networks, focusing on the impact of EG on harmonic distortion, voltage variations and dips. It is shown that assessment of the network power quality levels can be efficiently performed by means of suitable indices defined for either the entire system or portions of it. The usefulness of the approach is tested on a real case distribution network
