Why does a distribution grid needs intelligent management?
Yesterday and today
Page 11
New supply structure
due to:
Changed feed-in conditions
Wind power
Photovoltaic energy
Nuclear phase-out
Combined heat and power
plants
Biomass energy
New electrical consumers
Electric vehicles
Heat pumps
Electrical energy storage

Grid extension – how much is needed?
What is the solution?
Conventional versus intelligent grid
Page 15Bilfinger Mauell GmbH
DER integration requires a combination of grid
extension measures and implementation of
measuring and control technology
What is the solution?
Grid monitoring

Smart grid application for Mainova, Frankfurt
Project Description
Realization of two smart grids in the 400V distribution
grid
Intelligent grid protection instead of large investments
in new power lines
Automatic power control of decentralized generation
Automatic voltage regulation
Integrated grid state estimation
Is the solution already available?

Smart grid application for “DSO”, Ireland
Bilfinger Mauell GmbH is interested in:
Local partnerships for the development and
realisation of similar projects, focused on
the exceptions of the irish grid operators
and local regulations.
Potential in Ireland with local Partners?

Increasing amount of DERs requires intelligent grid management
The solution and it’s components are available
Cost-intensive conventional grid extension can be reduced
The solution is working independently
The solution can be integrated in different IT infrastructures
(Grid operation and service centers)
