Since most distribution systems are not designed to accept large scale power injections, these small generation units may impact on their interconnected networks. The quality of the supplied energy may be altered, and the reliability and the safety of the whole distribution system from LV to medium voltage (MV) levels may be affected. The aim of this paper is to establish a new methodology to find the best location for remotely controlled distributed generators (DG). As global optimizations with multi-objectives functions may be hazardous, and may lead to different solutions (locally optimal), the goal of the method is to provide an expert analysis of the system, to help the optimization process. The proposed methodology has been validated with a particular case of voltage profile (LV/MV). The test-system used for this study is a real urban network containing 11 feeders with 2 transformers of 36 MVA. One feeder was simulated with DG and managed.

This paper will present an overview of the project as a whole and will summarize the work already completed along within highlighting the ongoing activities.

Radial MV distribution grids can be protected by a single relay placed at the beginning of the feeder. But the future operation of distribution grids turning into Smart Grids will surely impose more complex operations. Therefore a more advanced protection scheme could be needed and could include several protection

These changes are triggered by several factors such as the event of distributed energy resources (DER) and the need to improve the quality of supply while achieving economical optima. Hence, several research initiatives, technological development and experiments have been launched worldwide to tackle this situation such as ldquoSmartGridsrdquo. This panel deals with some new decentralized operating modes for EDS management with high penetration of DER. These decentralized modes are based on distributing the management system locally and intelligently using advanced Information and Communication Technology (ICT). These concepts are being demonstrated through an experimental platform: an analogical micronetwork (muGrid). Functions such as fault management and high level of self adaptive architectures are developed for these new modes.
