Impacts of demand side management and micro-generation units on low voltage distribution radial networks

The increasing dissemination of micro-generation systems, interest in demand-side management actions as a tool potentially contributing for increasing the operational efficiency of power systems operation and higher penetration of renewables will originate scenarios in which these issues co-exist in the same low voltage distribution network. The impacts of these scenarios, namely on power quality, should be properly assessed. This paper presents a case study in which the impacts on voltage fluctuation and unbalance are assessed in a low voltage radial distribution network in which some micro-generation units are installed.
