Defining Smart Grids
The smart grid is a digital network that unites
electrical providers, power-delivery systems and
customers, and allows two-way communication
between the utility and its customers. Smart grids have
the potential to improve the efficiency of energy
distribution and usage, both through the grids’ design
and through consumer participation.
Ideally, smart grids are also intended to work with
multiple power sources, including wind and solar
sources, and perhaps eventually small individual
sources and ones that provide automotive power.
Smart Grid Development: Objectives
•

Smart Grid Development: Objectives
Eliminate waste
Smart Grids
Enhance network reliability and stability, to
prevent electrical blackouts
Balance the fluctuating power generation from
renewable energies and electricity consumtion
The use of „smart meters“ helps consumer to
reduce consumption and provides efficency

E-Energy – Smart Grids made in Germany

Much more energy is produced by decentralized renewable
energy sources

Energy generation and consumption have to be kept
continuously in balance
Smart Grids
E-Energy – Smart Grids made in Germany

“E-Energy: ICT-based Energy System of the Future” is a new support
and funding priority undertaken by the Federal Ministry of Economics
and Technology (BMWi) in 2008.

Primary goal: create E-Energy model regions that demonstrate how the
potential for optimization presented by information and communication
technologies (ICT) can be exploited to achieve efficiency, supply
security and environmental compatibility.

The BMWi finances four model regions (40 Millions Euros).

The Federal Ministry for Environment, Nature Conservation
and Nuclear Safety (BMU) finances other 2 model regions.
E-Energy: Goals

ICT system concepts, which optimize the efficiency, supply
security and environmental compatibility of the electricity
supply system are developed and tested in real-time in
regional models.

Climate Conservation will be strengthened.

Job creation and new markets growth (energy retailers, new
service provider, metering operators).
E-Energy: the six Model Regions
E-Energy: an example - eTellience

Whole new marketplace for energy developing in and around
Cuxhaven.

Consumers can use this marketplace to buy, sell electricity, offer
system services and idle power, and help reduce the load on the
power grid.

Private households can put minute amounts of electricity on the
market by using almost fully automated plug-and-play appliances.

2 refrigerated warehouses; 1 wind park; 2 city baths Cuxhaven; a
clarification plant; 1 block heat and power plant.

eTelligence: First Findings and Results

Thermo-electric energy systems can be used very well to
save energy

eTelligence seeks to achieve a local balance of electricity
generation wind from wind power and electricity
consumption by using large electric cooling facilities.

Modules are used through which the commercial energy
consumers can be connected to the virtual power plant.
E-Energy: first findings and results

Savings of up to 5% have been reached in the private sector
in the first pilot tests „on the field“.

In different E-Energy projects some firms registered even up
to 20% energy savings.

Obstacles and barriers to be removed
Transmission grid expansion will need to surmount following (still existing)
barriers:

Technology barriers (e.g. data privacy)

R&D organization barriers, such as fragmentation and duplication efforts

Market failures and distortions
There are also other obstacles connected to the increase of RES in the system,
such as:

National incentives can create cross-border obstacles to RES deployment

The increasing amount of RES in the system reduces available transmission
capacity for TSOs’ commercial purposes and increases the need to use the
system security margin to ensure network stability

Higher renewables penetration = a greater need for backup capacity
