Smart Transmission Solutions

One of Terna's main needs is to make the transmission grid dynamic, capable of evolving rapidly and effectively in the face of scenarios that change unexpectedly and that cannot be easily predicted.

In the Development Plan, Terna has planned interventions that can ensure, in various operating conditions, the security, reliability and efficiency requirements of the electricity system, and at the same time foster the integration of increased production from renewable sources not directly connected to the NTG.

Among these are the following:

  • the installation of electricity equipment (PST - Phase Shifting Transformers) for controlling energy flows on the High and Very-High voltage grid;
  • the installation of synchronous compensators for the improved stability and security of system operation;
  • the installation of reactors and condensers for the correct management of reactive energy flows on the grid and the consequent reduction of costs for the dispatching market;
  • the use of high capacity conductors that function in relation to temperature (Dynamic Thermal Rating- DTR) to maximise the transmission capacity of existing lines;
  • the testing of diffused accumulation systems to maximise the use of resources from renewable sources and improve the regulation of the high and very-high voltage system;
  • initiatives based on smart logic, aimed at improving the forecast and control of distributed generation.

These solutions are generally characterised by reduced environmental impact (as they allow the maximal use of the existing asset) and implementation times and costs normally lower than those required for the implementation of new network infrastructure (high voltage lines and stations).
