5. Projects: MicroGrid 2011 - Integral EU project
– Develop and validate
innovative control strategies
and network architectures
for active networks with
large-scale penetration of
renewable sources and
distributed generation
– Increase market exposure of
small ‘prosumers
(consumers with local
generation)
– Normal and Critical
Operating Scenarios

18. A Very Different Future?
• As the number of loads and generators connected to the grid
increases;
– the controllability and control model of the grid will change
– reliability will only be maintained through distributed intelligence and
control
• Complexities at the edge – DR programs, DG programs, MicroGrids,
grid divorce, AMI / HAN
• This strongly suggests a more highly distributed energy system will
play a major role in the modern grid.

19. Hybrid Integrated Systems (Microgrid) Trends
• MicroGrids
will
con1nue
to
be
an
important
niche
for
high-­‐
reliability
and
emerging
markets
(premium
product
or
grid
parity
driven)
• Integrated
systems
with
capabili1es
to
locally
reduce
the
renewable
genera1on
variability
(VRG)
in
output
will
increase
the
viability
of
renewables
• Predic1on
that
hybrid
systems
(Renewables
and
natural
gas,
Renewables
and
storage,
Grid-­‐Friendly
Renewables)
will
become
the
next
mass
