Using LTE and fiber
Advanced automation:
OLTC (Primary SS), centralsied control using measurment data
Direct control of P, Q from DG enabled
Originaly concieved to implement this control
The regulatory and legal framework do not yet regulate the specific technical solutions to "control“ MV customers, and do not envisage a role for the DSO in installing control devices on the customer side.

12. A regional charging network for e-MOBILITY
Development of a network of 74 public charging infrastructures for fully integrated electric vehicles with the distribution network, located throughout the regional territory along the main routes.
Refurbished Infrastructure Designed with Open, Interoperable, and Multivendor Philosophy to Accept Clients With Contracts Of Any Power Trader
Coverage of the region and connections with the neighboring regions by maximizing the efficiency of the charging infrastructures already present on the regional territory
Simultaneous charging of multiple vehicles for a lesser impact on the territory and greater serviceability
Central Remote Control System (EMM) for the entire network supervision and complete management of the entire charging process 12

13. The scenario Over 30 Municipalities Involved 16 Multi Fast Recharge
Figures
Over 30 Municipalities Involved
16 Multi Fast Recharge
58 Pole Stations
164 Simultaneous charging points
Project was updated to include multi charge / fast charging stations:
 50 kW DC power (either CHAdeMO or Combo2);
 43 kW AC power Type 2, 63 A;
 22 kW AC power Type 2, 32 A.
Each station contains two three-phase smart meters which measures the consumption during the charging process.
A microprocessor control unit is responsible for managing the charging and communication functionalities:
• it acquires from the smart meter, via optical port and a serial transport protocol IEC 61107, all measurement data required for service delivery;
Finding optimal installation point on the grid to reduce connection cost is constrained by other needs: geographical location based on traffic flows, tourist areas, etc and host site owner (commercial center, service station, etc) 13

14. Enabling Demand Response for LV Customers
Free distribution of 30,000 Smart Info + kits, an innovative system for providing the customer with information acquired from the smart meter and streamlining energy consumption in a simple way.
Smart info info can be viewed through a wifi connection device (dongle) and built-in (sw / web-app) devices for displaying consumer data over PCs and / or mobile devices.
Smart info has been
designed by e-distribuzione
allows end users to have the certified information on electricity
Making the data managed by their smart meter at their fingertips.
It can be plugged in every domestic socket to start data collection from the smart meter through power line.
There are General purpose or dedicated user interfaces aimed at data visualization (e.g. displays, pc) can be connected using two dedicated USB ports.
Moreover, the use of a wireless USB dongle makes communication with domestic appliances easier.
- Experience has shown that portable devices (smart phone/tablet) are preferred interface over wall mounted display 14

15. The Benefits of Puglia Active Network
Economy
Environment
Significant distributed resources in the region will support the economy and productivity
Valuation of competencies both within E Distribuzione
Supports Local business development
New value-added services addressed to citizens
Integration of renewable energy
Reduced network losses
Intelligent management of energy consumption
Realisation of new infrastructure for a new model of zero emission transport
New Value Added Services for Resident Citizens: The proposed Electricity Infrastructure Infrastructure may favor the development of eco-friendly services for citizens by public and private companies such as zero emission delivery, car sharing, etc. 15

16. Main Outcomes
Verification that advanced monitoring and control system on electrical distribution network has attainable benefits for increasing hosting capacity of renewable generation sources.
Demonstrated reduced costs as the scale of the deployment is increased
Further potential for increased flexibility that can be facilitated
Installations of more efficient charging station including fast recharge and better distribution, allowing an increased output
Realisation of improved customer engagement resulting from Smart Info deployment
Increasing HC by maintaining voltage profile within limits by controlling at
At primary SS without advanced monitoring: 3%
At primary SS with advanced monitoring: >10%
AT primary SS with advanced monitoring and controlling DG: >20%
Reduced costs
One example: cost of telecommunications lower than previous expectations base on smaller demonstration projects. LTE comms between secondary SS and primary SS. In many cases in this project 4G already available.
Another example: Isernia project- Only one SS. cost around €5M for one primary SS. Here 102 primary SS’s -cost is around €1M per SS. Economies of scale. Drastic reduction. Although case by case in some cases we were looking at 20 to 25% of smaller demonstration or pilot projects.
Further increase flex by UNLOCKING full potential. Regulatory framework would have to facilitate ability to control active or reactive power generated. 15
