  • Power generation and distributed Smart Grids. One of the main objectives of the Smart Grids is the substitution of a centralized operating infrastructure (a large system with points of weakness), with a more flexible and resilient system, articulated in smaller structures, able to compensate for the weaknesses of the networks with some degree of autonomy in order to avoid a domino effect of fault propagation. The Group’s research is aimed to develop centralized and decentralized controllers that optimize plant management of Distributed Generation. This, in order to increase DG connectivity to the distribution systems and ensure the provision of certain Ancillary Services to the transmission grid. Other research is also carried out on the feasibility of supplying portions of the network operating in the island by the contribute of renewable sources.
  • Transmission and Super Grid technologies for power transmission. The research has addressed the environmental impact of electricity transmission systems, both in the context of traditional technologies (overhead lines) that those innovative (GIL power lines and cables AAT with extruded insulation XLPE). The idea of “multi-corridor” with a simultaneous presence of transmission lines for electricity and other services (rail, highway) brought to the post of a feasibility study for three years funded by the EC under the program TEN TREN. The Group has also financed a study on the integration of a 500 kV HVDC link in future railway tunnel between Lyon and Turin, and for rationalizing the Fusina, where the overhead lines will be replaced by cable connections at 380 kV and 220 kV.
  • Electric Energy Storage in transmission and distribution systems. Following the development of power generation from renewable sources it is derived the need for strengthening the transmission network in areas with great availability. The timing adjustment is not compatible with the urgent intervention have stimulated the development of technological innovations such as the systems of diffused storage of electricity capable of leveling out peak transit to cope with the congestion line. The Group is engaged in research of electrochemical storage systems for stationary electricity on the AT Italian with the currently most promising technologies (eg. Sodium-nickel chloride) by addressing the issues of access and control, and performing risk analysis in the light of environmental regulations.
