ABSTRACT:
In
this
seminar,
the
problem
of
planning
and
upgrading
an
electric
urban
distribution
network
is
considered.
Although
network
planning
has
attracted
considerable
attention
in
the
field
of
power
systems
since
the
early
1970s,
the
urban
distribution
network
of
Milan
(Italy)
shows
significant
and
challenging
peculiarities.
Before
deregulation
in
1999,
two
separate
distribution
networks,
operated
by
two
different
companies,
were
in
place
and
developed
independent
and
uncoordinated.
After
deregulation,
the
two
companies
merged
and
now
there
is
a
single
company
in
charge
of
planning
and
operation
of
the
single
network,
which
is
made
by
portions
at
several
different
voltages,
substations
with
different
schemes
and
practices,
and
different
design
philosophies.
The
research
presented
is
based
on
the
goal
of
trying
as
much
as
possible
to
merge
the
different
areas
in
a
coordinated
and
efficient
approach,
minimizing
investment
costs
and
taking
into
account
logistic
issues,
operating
practices
and
regulatory
constraints.
The
problem
is
tackled
by
a
mixed
integer
linear
programming
(MILP)
approach
for
planning
a
new
network
configuration,
called
2-step
ladder
topology,
which
optimally
integrates
the
two
networks
already
in
place.
The
distribution
system
has
to
be
shaped
considering
electric
power
cable
joints
already
in
place.
Some
results
are
presented
with
reference
to
a
part
of
the
real
distribution
network
of
Milan.
BIOGRAPHY:
Prof.
Alberto
Berizzi
obtained
the
PhD
Degree
in
Electrical
Engineering
(1994)
at
the
Politecnico
di
Milano.
Since
2006
he
has
been
a
full
professor
of
Electric
Power
Systems.
Since
2011,
he
has
been
responsible
for
the
PhD
program
in
Electrical
Engineering
at
the
Politecnico.
His
research
has
been
published
in
about
150
papers
and
publications
in
the
following
fields:
• security issues of power systems;
• power system operation and planning and the electricity market operation;
• large power system dynamic perturbations;
• operation of Renewable in HV/MV/LV distribution systems, in both connected and islanded operation. In particular, congestion management, voltage control and islanding.
He is a member of the IEEE Voltage Stability Subcommittee and he was a member of the Task Force “Blackouts experience, mitigation and role of the new technologies” of the IEEE PES Power System Dynamic Performance Committee. He has also been a member of the CIGRE WG C1.17 "Planning to manage power interruption events". He has been responsible for many research projects, both at the national and international level. In particular, for what EU funded projects is concerned, he participated in the e-Highways 2050 project, and he is currently working for the Migrate and Osmose projects, funded by Horizon 2020.
