The project aims at developing a unique device for electricity networks: A superconducting fault current limiter (SFCL) based on coated conductor YBCO tape (cc-tape) or 2nd Generation HTS tape. The general trend in Europe to a higher meshing of distribution networks and the rapid growing integration of renewable energy sources leads to an increase of the fault current level by every new installation. As substations ratings are coming to their limits network operators have to either decline additional installations to their grids or to upgrade if not rebuild complete substations. The SFCL provides a solution to deal with the increasing incidence and level of fault currents and will contribute to improving the performance, stability and efficiency of electricity grids. It can be applied as a new tool for grid operation and will enhance the flexibility for further grid planning. SFCL are considered to be the most attractive superconducting devices as they offer unparalleled features compared to conventional techniques such as automatic ultrafast and effective current limitation, no external trigger (fail safe), rapid self recovery and negligible impedance during operation. In contrast to conventional solutions resistive type SFCL are also suitable for higher voltage levels. So far developed SFCL prototypes based on BSCCO material are exhibiting significant AC-losses at higher currents which oppose their commercial introduction. Today, the availability of cc-tape in longer lengths at reasonable cost makes a commercial breakthrough of FCL possible with unique features such as compactness, short recovery-time, low AC-losses. Leading industrial and academic institutions from Europe have teamed up to design, build, and test the first full 3-phase cc-tape FCL worldwide. The device will be long term tested or even permanently installed in the medium voltage grid. The strong demand for this device is emphasized by the large number of electric utilities participating as partner

The IDE4L project will define, develop and demonstrate the entire system of distribution network automation, IT systems and applications for active network management. Active distribution networks will utilize distributed energy resources (DERs) for network management including both real time operation and long-term network planning viewpoints. DERs consist of aggregated distributed generation, demand response and other controllable loads. The starting point of development are existing distribution networks, their management systems, future expectations of penetration of renewable energy sources and high expectations of customers for continuity of service. The research and development work done in the project integrates many existing automation and IT systems utilizing available standard protocols in an innovative way and develops new applications based on that system. Demonstrations of integrated automation system and applications will be realized in real life networks in different parts of Europe where are connected large and small scale PV, wind power, heat pumps and EVs located in urban and rural areas. The outcome of the project will be applicable in very near future in all over Europe. Integrated distribution network automation system will be capable of monitoring, controlling, managing fast changing conditions and integrating large number of DERs in distribution network. Technical solutions utilizing the automation system will enhance the reliability of distribution network by improving fault location, isolation and supply restoration, will increase the hosting capacity of distribution network for renewables by managing network congestion with DERs, will optimize the operation of DERs by aggregating DERs and coordinating these with distribution network management, and will monitor dynamic behaviour of distribution network for system management.

Distribution System Operators are working to improve and extend the level of control of their grid, as response to the new challenges of integrating distribution renewable sources and improving the quality of their service. In doing so, they need also to face up to the problem of reaching their transformer stations via a suitable communication technology, which can guarantee a balanced tradeoff between investments - in terms of cost and time for installation - and benefits - in term of performances (bandwidth, transfer time, reliability and availability). The paper describes real-life experiments carried out by A2A Reti Elettriche SpA - an Italian Distribution System Operator - with the Medium Voltage Broadband Power Line communication (MV-BPL), which is considered one of the most interesting communication technology for Smart Grid applications. Some preliminary results are reported. The paper also describes the hybrid communication - MV-BPL and high rate wireless - defined by the 7th Framework Program European Project INTEGRIS as a way to improve the performance of the MV-BPL. © 2012 IEEE.

To improve quality of service of the electrical energy distribution and to exploit distributed energy resources (e.g. distributed generation) real-time monitoring of the power grid should be extended to include secondary substations, medium voltage and low voltage grids, up to end-users, gathering and processing all these data where they are really needed. The paper describes the Integrated Distribution Network Monitoring use case defined by the 7th Framework Program European Project INTEGRIS and its distributed and hierarchical ICT architecture designed to efficiently fulfill both communication and application requirements foreseen for the Smart Grid. © 2011 IEEE.

The distribution grid is the infrastructure that transports electrical energy generated by large plants that are long distances away to the final user. A typical distribution grid consists of High-to-Medium Voltage (HV/MV) transformation centers; the MV grid; Medium-to-Low Voltage (MV/LV) transformation centers; and the LV grid, both three-phase and single-phase. Residential and commercial customers are mainly connected to the LV, while large industrial facilities are connected to the MV. © 1998-2012 IEEE.

New needs of distribution system monitoring and automation have been raised in these years as the level of renewable energy sources penetration increases. Monitoring, protection, and synchronization applications needed by new Smart Grid systems mandate a capillary communication with primary and secondary substation, which cannot be implemented in time just with traditional media, such as Fiber Optics. Broadband Power Line over Medium Voltage (MV-BPL) grid could be a viable solution but a comprehensive characterization is still missing. The paper describes an experimental evaluation of service latency in a real MV-BPL design for the distribution grid management in Italy. The preliminary analysis states that 95% of the service requests are transferred on the network with a round-trip time lower than 120 ms even in the case of four hops. © 2012 IEEE.

The IEC 61850 standard allows for a structured grid automation system where critical tasks like grid protections, renewable energy sources management, synchronized measurements, and monitoring applications share the communication network. So far, the use of IEC 61850 has been mainly limited to the primary substations, but more interesting could be the coordinated actions between primary and secondary substations in order to quickly react to faults and to reduce service downtimes for final customers. Unfortunately, the communication networks between primary and secondary substations are today only partially deployed. Considering this context, the broadband power line over medium voltage grid (MV-BPL) could be a suitable solution for closing the communication gaps between substations that use IEC 61850. The main objective of this paper is to present the outcomes of the first phase of a project whose final goal is the implementation in real grids of distribution grid automation based on IEC 61850. A new and comprehensive set of experiments on a real (and in service) medium voltage grid in Italy has been designed and carried out. The practicability of IEC 61850 communication over the distribution grid is assessed comparing the time characteristics of the MV-BPL against the transfer time classes of the IEC 61850, determining which IEC 61850 services may be transported over MV-BPL. The experimental long-term analysis highlights that more than 90% of the service requests are transferred on the network with a round-trip time lower than 40 ms even in the case of four hops, a time which is compatible with the IEC 61850 fast automatic interactions on MV grid. © 1963-2012 IEEE.

The business of distribution system operators is rapidly evolving as the distribution grid is hosting more distributed energy resources. Technology for monitoring, control, and protecting the grid is progressively pervading the lower segment of the network. These changes require a performing communication infrastructure to enable data exchange among the control centers of the grid. The 7th Framework Program European Project INTEGRIS proposes a hybrid infrastructure-based on broadband power line (BPL), Wi-Fi, and fiber optics (FO)-to enable services for grid management. This mix of technologies provides a balanced tradeoff between investments and benefits, meeting most of the requirements of the smart grid. This paper investigates the technologies that could be adopted and describes the experimental assessment performed in an operational environment in Italy. Using this installation, transfer time, time synchronization accuracy, dependability, and throughput are evaluated and analyzed over a long-term campaign. Results show that the FO is the best communication media, able to provide a two-way latency of 3 ms (95 percentile), whereas BPL has a two-way latency of 57 ms (95 percentile-4 hops). Those results confirm that a careful selection of the technologies is required to satisfy requirements of smart grid. © 2015 IEEE.

Ricerca sul Sistema Energetico S.p.A. (RSE) has been gaining a relevant experience in the simulation, design and installation of resistive-type Superconducting Fault Current Limiter (SFCL) devices for more than five years in the framework of a R&D national project funded by the Ricerca di Sistema (RdS). The most recent outcome of this research activity is the installation of a resistive-type BSCCO-based 9 kV / 3.4 MVA SFCL device in a single feeder branch of the Medium Voltage (MV) distribution network managed by A2A Reti Elettriche S.p.A (A2A) in the Milano area. This installation represents the first SFCL successfully installed in Italy. In this paper, we report on the main outcomes after a more than 1-year long steady-state field testing activity. The design of an upgraded device to be installed in the same substation has already been initiated: the new SFCL will allow to protect four different feeders, therefore implying a device upgrade up to 15.6 MVA. © Published under licence by IOP Publishing Ltd.
