Clustering of Distributed Generation
Why clusters do not form?
PV (Photo Voltaic) Distributed Generation»
Clustering of Distributed Generation
• 50 MW total PV peak power• 6060 PV installations• 9000 LV Feeders
Average by feeder• < 0,7 installations• 9 kW
9000 total LVF
2890 LVF with PV
290 10° Percentile
29 1° Percentile
• 0,7 • 9 kW
• 2• 18 kW
• 6• 97 kW
• 10• 236 kW
• installations• Power kW
Average by feeder
PV (Photo Voltaic) Distributed Generation »
Clustering of Distributed Generation
• 50 MW PV total peak power• 1400 MW Contract power on LVF• On average PV 3% of Contract Power
But average values are missleading• Over 100 feeders have ratio PV / Contract power > 100%• 10° percentile of Feeders has PV / Contract power > 40%

PESSE, Emergency Plan for the safety of Electric SystemUnder the coordination of Terna (HV transmission) Distribution companies disconnect load in a planned and selective way, in order to avoid un-controlled black outs.

PESSE – What ? Why ?
PESSE – How it works?
All residential and commercial customers are divided in groups For each group a rolling outage is planned for up to 1,5 hours per day.
PESSE – How it works ?
Optimize the groups » “domestic customers with life saving
equipment are excluded from the planned outages”
Distributed Generation – not only PV

Data &Processes
data is trust worthy (updated and
complete) only as long as it is produced or used by a primary
company process
Robust Flexible
SoftwareAEEG releases each
year new rules, positive feed-back on
processes that can be managed and
optimized
Competent People on
Processes & Sw
dedication and (self)training to
exploit all the power in Sw (old and new) of the tech pyramid
3 key factors to “do more with less”

To be Smart...
Smart Local Governments
Local GovernmentsUsing GIS-based Tax Solutions to be very effective in collecting real estate taxes and to fight tax elusion
Smart Multi Utilities
MultiutilitiesUsing GIS-based Solutions in order to better run the distribution network, reduce and manage power downwtime
Smart Provinces And Regions
Province e RegioniSoluzioni per il monitoraggio e il controllo permettono una gestione più efficace del traffico e una migliore manutenzione delle infrastrutture stradali
10 Regions 18 Provinces 3 Regional Environment Agencies
(ARPA) 2 Government Departments 10 Multi Utility Companies 15 Main Cities More than 50 Smaller Municipalities
