SMART GRID – Communication, Measurement and Automation Study, design and development of islanded and interconnected EMC compliant smart grids

ABSTRACT

In the last years, the diffusion of distributed generation systems (DGs), mainly based on renewable energy sources (RES), has required the need of a higher level of automation of the electrical networks, which in the next future has to become smart grids. In this evolution, new measurement tools and strategies and bidirectional communication systems are required, in order to implement not only simple functions (such as the disconnection of a DG in the case of unwanted islanding), but also more complex tasks such as the management of islanding in the presence of faults in other parts of the network (i.e. safe islanding), reconfiguration of the network topology, remote control of DGs (to allow their participation in the regulation of voltage and frequency), power quality analyses.

SUMMARY

A key role in the distribution grid can be played by the storage systems (SS), especially those decentralized (including even those of electric vehicles). In fact, when GDs from RES are present in the network, the SS can allow the energy storage during periods when the energy production overcomes the load consumption, thus preventing the reversal of power flows on the network.

OBJECTIVES

The general aim of the project is the development of innovative technology for smart grids, in order to increase the integration of distributed generation (DG) based on renewable energy sources (RES).
In detail the objectives of the project are:

  • design of new intelligent measurement systems for the remote monitoring of load consumption and power quality of the grid;
  • study of innovative algorithms for the load flow analysis and the anti-islanding protection;
  • development of new communication systems for the information exchange between the different devices connected to the grid, with a particular focus on the Power Line Communication technology;
  • the study and development of smart interface devices (ID) for GDs, with and without decentralized SS;
  • analysis of the electromagnetic compatibility of the developed devices and systems devices for the enhancement of the network reliability.
