Abstract
National and internationals grid codes define the connection rules for passive and active users, guaranteeing the electrical power system stability and safety. Recently, the increasing diffusion of Distributed Generators from Renewable Energy Sources, mainly interfaced through electronic converters, has called for a drastic review of traditional approaches to distribution network operation. As a consequence, new regulating functions, aiming to support network stability by regulating local units power flows, have been defined, and others are under investigation. The paper discusses the role of existing and proposed stabilizing actions in terms of unintentional islanding identification, according to the Low Voltage interface protection characteristics.
