Integration of new sources of energy in the Italian distribution network

In last years, Italian distribution network is registering a progressive diffusion of distributed generation (DG), in both HV and MV grids, driven by European and national incentives, especially for renewable energy sources (RES). The increase of generation in MV network may produce several problems in a regulatory context with high focus on quality of service and costs reduction. In fact, MV grid is conceived to be operated in a radial scheme, with a unidirectional flow of energy. The connection of DG is defined both by the regulator and the distribution companies. However, to allow a higher penetration of DG, the "connect and forget" philosophy should evolve in a "full integration" one, through a local energy management. Distribution companies are acting both at generators\´ and at customers\´ side, through new ICT systems and electronic metering. Clear, stable and uniform rules should be applied in a system approach
