Distribution networks will experience a deep mutation concerning their planning and operation rules due to the expected increase of distributed generation (DG) interconnection to the grid. Indeed, the opening of the electricity market or the growing global concern for environmental issues will lead to a massive development of DGs. Yet, a too large amount of DGs could raise technical problems on distribution...
Nowadays, distribution networks are facing tremendous challenges. Actually, the opening of the energy market, the wish to preserve the environment and the reduction of fossil energy stocks have lead to use more and more distributed, renewable and local energy resources, such as wind and photovoltaic generators. These generating units are mostly connected to the distribution networks. With the increase...
Electrical distribution systems (EDS) are undergoing some significant changes at various scales and levels. 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...
Increasing complexity of interconnected electricity grids with a high integration level of dispersed generators leads that ldquobusiness as usualrdquo operating modes and regular devices in distribution networks are not efficient enough to ensure the centralized management of a large amount of information and high-level functionalities (advanced distribution automation-ADA) for future electricity...
The major change in the last decade concerning distribution network is related to the penetration of distributed generation (DG). The current practice in France concerning the connection of DG was to fit the network to the worse case of use of DG to avoid any problem. This approach will reach his limits and many developments will be necessary to optimize the network operation, taking the presence...
In this paper a novel approach for fault location in distribution networks is presented. The distributed generator's (DG) effect in such a network is studied and its influence on a simple fault location method is analyzed. Two DG models are considered - an ideal and a realistic one, for the validation of the fault location algorithm. Simulations were performed on ATP-EMTP, in order to test the analytical...
The expected insertion of DG (distributed generation) in the distribution networks entailed by environmental and economical aspects will modify the grid architectures and the operation mode. A more flexible operated system will emerge through various applications and developments of the distribution automation. In this paper a general (electrical and software) topology, a clear definition of the applications...
