“The fossil-fuel
infrastructure constitutes
the costliest and most
extensive infrastructure that
the world has ever built.”

“It would be difficult to
imagine a world today
without electricity.”
Michael B. McElroy
The North American electricity grid is the world's largest and
most complex system of power generation, transmission, and
distribution. It has 340,000 km of high-voltage transmission lines,
and total assets of more than $1 trillion.

Complex Systems
6 © CEFRIEL - Milano, 05/11/2008
“The philosophy of building some slack
into technical systems has given way to a
more refined approach where, aided by
more sophisticated instrumentation and
computing, components can be matched
more precisely to needs. While such
refinement has obvious economic
justifications, it does increase the
vulnerability of the system.”
Alexandra Von Meier, “Electric Power Systems”
Interdependencies between key
infrastructures can create subtle interactions
that often lead to unpredictable behaviors.

The Challenge of Complexity

The 2003 Italy blackout
The power line that supplied
electricity to Italy from Switzerland
was damaged by storms, triggering a
cascading effect that caused ENEL to
loose control of the grid in the next 4
seconds.
The power grid and the SCADA network (shifted above the map)
that were implicated in the worst electrical blackout that occurred
in Italy (September 2003).
The Challenge of Complexity

The Challenge of Complexity
9
According to Tainter, societies become
more complex as they try to solve
problems.
But such complexity requires a
substantial consumption of
resources, and this leads to collapse
from diminishing returns.
Up to now, the “complexification”
of strategic infrastructures has
been made possible by the
spectacular advances in ICT.
Is this trend going to last?

Answers to the Challenge
1. Systems Approach
10 © CEFRIEL - Milano, 05/11/2008
� The systems approach is a process of conceptualizing,
modeling and evaluating things in a “synthetic way” as
opposed to a more analytical, engineering approach
� There are no absolute rules or specific tools to use
� Modeling complex systems is hindered by:
- Diversity of system components
- Cooperation between diversified workgroups
- Large range of abstraction layers required to
describe the problem

Answers to the Challenge
2. Control
ICT is the only feasible way to control
modern, highly distributed, geographically
widespread systems requiring
� High initial investments
� Easy field installation
� Reduced maintenance
� Ideally, energy autonomous field devices
� Interoperability
� Flexibility and capability of evolution
![Page 12: The Value of Data for Strategic Infrastructure Management · The Value of Data for Strategic Infrastructure Management Big Data Analytics Conference 2013 Roma,17 ottobre 2013](https://reader033.vdocuments.us/reader033/viewer/2022060307/5f09ed397e708231d4292ba1/html5/thumbnails/12.jpg)
The Value of Data
12 © CEFRIEL - Milano, 17/10/2013
� Leverage existing monitoring
infrastructures (also from
third parties)
� Avoid heavy capital
investments in new assets
� Reduce solution deployment
time
� Potentially switch from
reaction-based to prediction-
based system operations
