WP 5 – Task 1 – Italian Pilot Project

Energy situation

3

Large increasingof RES in the last

10 years

New issues in terms of powermanagement of

the electrical grid

NEW CHALLENGES• Active Power rise up from MV to HV grid• Unpredictability of RES• Needs to improve the infrastructure for monitoring and control of

MV and LV levels

Italiancontext

WP 5 – Task 1 – Italian Pilot Project

A smart management of the electrical grid, by all the actors involved, could

help to face the new challenges

Interaction and collaboration between TSOs and DSOs

• It could provide a better observability and allows to take advantage from

electrical resource.

• The electrical system could be more flexible
