We are here: Allgäu Region

The Renewable Energies and the German Energy Transition changes the system of energy generation and distribution. Further the distribution network operators (DNO) are becoming Smart Grid operators.
- What are the changes caused by renewable energies?
- What means intelligence in the network?
- Which types of smart grid components are already available?- How can intelligent Microgrids as parts of existing grids and for
off grid areas be helpfully in the future?

… to minimize costs for grid expansion
Conventional grid expansion in low and medium voltage level of Germany will cost until 2030 approx. 16 bn. €
Why do we think today about smart grids

… to avoid voltage band violation and system overloading

Why do we think today about smart grids
… to be able to implement new technologies like electro mobility (EV) and stationary energy storage systems usefully in the grid

… the share of decentralized renewable energies will rise and approx. 90% of the renewable energies feed in the distribution grid.
… new technologies (EV and batteries) will be integrated in the distribution grid… for distribution grids are almost no measurement data available and therefore
only few insight in voltage band violations and operational equipment overload
Why do we think today about smart grids
Upcoming changes in the grid need measurement data as a base for intelligent actions

• Project IRENE: “Integration of renewable energies and electro mobility” • Project IREN2: “Intelligent power grids, Microgrids and battery storages”
Both Projects in the town Wildpoldsried Rural area – approx. 2500 habitants High percentage of renewable energy feed in (P = 8.175 MW)
(situation in 2011 comparable with expected status of 2020 in Germany) produces 2.5 – 3 times more energy than they use

Intelligent methods and components
Controllable distribution transformer (rONT)
Benefits for stabilizing the grid voltage and smoothing PV peaks
Stationary battery energy storage system
egrid - Thomas Eberl 17Bogotá - el 5 de Mayo de 2016
• More than 30% reduction of the grid expansion costs (in total 3.2 Mio. €/a)
• The gird is able to supply approx. 10,000 electrical vehicles in the Allgäu region (Scenario 2020: 1 Mio EV’s in Germany)
• Stationary battery storage systems can be integrated usefully in the distribution grid
Benefits of intelligent methods

Microgrid Management

The Energy Transition and the upcoming Nuclear Power phase-out changes the energy production and distribution systems:fewer big scale power plants results in a reduction of services like
• Reactive power supply• Black start capability after an error
Questions in the project IREN2: • Can grids with a high penetration of renewables run autonomously?
Microgrid in island operation approach • Can these kinds of grid areas replace large conventional power plants?
Topological power plant
Motivation for Microgrids in Germany
egrid - Thomas Eberl 23Bogotá - el 5 de Mayo de 2016
Microgrid in Wildpoldsried The existing grid was expanded: Control technology, battery storage systems, flexible and converter-controlled DC-link between MV and LV level, synchronization and protection equipment, two back-up generators (vegetable oil and biodiesel)
Research objectives:• Operation as an island grid –
disconnected from the main grid
• Utilization of the Microgrid as a topological power plant (provision of ancillary services)
• Stable and economically optimized grid operation
IREN2 is the first Microgrid test of its kind outside of a laboratory.

Microgrid – island operation
What a Microgrid provides:• Plants have to ensure grid stability
at all times – particularly with fluctuating power infeed from solar and wind power.
• A control system maintains the balance between generation and consumption – this provides for autonomous operation.
Renewable and conventional energy production units form a hybrid structure. This ensures grid stability and optimizes efficiency during operation.
A Microgrid enables the profitable use of renewable resources independently of the supply grid.
egrid - Thomas Eberl 25Bogotá - el 5 de Mayo de 2016
Microgrid – topological power plants
A Microgrid provides ancillary services from the distribution grid for the market.
What a topological power plant provides:
• The potential for ancillary services is predicted.• If ancillary services are agreed upon, the
Microgrid has to be capable of supplying them at any time.• A control system ensures that the
distributed energy sources provide ancillary services in addition to normal operation.
At times the Microgrid can replace conventional power plants by supplying ancillary services.
IREN2Microgrid
egrid - Thoatmas Eberl 26Bogotá - el 5 de Mayo de 2016
All applications tried and tested in Germany‘s Allgäu region could be used in other applications world wide:
IREN2 : Results are Worldwide transferable
• Rural areas with an increasing demand for energy• Geographic islands and • Regions without grid connection• Self-contained industrial grids
The grid planning and optimization strategies could be used for any grid…
