Overwiew of the Italian Demo

The demonstration, addressing Medium Voltage (MV) network, aims at realizing an advanced control system communicating with all the network relevant nodes (MV generators, HV/MV and MV/LV substations, and a storage facility), through an “always on”, IP standard-based communication solution.

The new system will allow to:

  • Implement Voltage Control (at all nodes) and Power Flow Control in the MV network
  • Develop new procedures for managing efficiently and reliably generation units disconnection in the event of unwanted islanding
  • Test and assess the use of a storage facility for optimized Network Operations and Energy Management
  • Enable the dispatching of the renewable generation on the MV network

Demonstration site is an area with high penetration of solar generation and relatively low consumptions. The climate conditions are Mediterranean and the distribution network is particularly representative of the grid of the southern Europe.

Main objectives

  • Implement Active Control and Demand Response of Decentralized Energy Resources (DER) such as generators, Controllable loads and storage to increase medium voltage network hosting capacity of renewable generation
  • Help the medium voltage distribution network to become more flexible with advanced network operation and energy management capabilities
  • Demonstrate advanced solutions under real operating conditions and on large scale

Main outcomes are the following:

  • Increase the Medium Voltage network hosting capacity of renewable generation
  • Assess the impact of new control techniques
  • Enhance the security of the electric system
