Student project: DC microgrid neighborhoods

Assessment of the effect of local supply & demand- balancing in the distribution system

Project Goal:

The student will work on different scenarios of direct cur-

rent microgrids in a “green energy neighborhood”. Espe-

cially in European electric neighborhoods PV systems and

CHP have to be taken into account.

Description:

▪ Literature Search and Review

▪ Evaluation of generation and load profiles

▪ Data collection and analysis

▪ Development and testing of different grid structures

and scenarios

Requirements:

▪ Candidates should have at least completed the 2nd

year of Electrical Engineering or similar courses in

the context of energy

▪ Good knowledge of system components and the dis-

tribution grid are favorable

We offer you:

▪ Practical exchange with scientist and industrial com-

panies in the Flexible Electrical Networks Research

Campus Framework

▪ A personal project consultant (scientist)

▪ A young and dynamic team with a pleasant work at-

mosphere

Context of the Project:

The student project is embedded in the context of direct

current (DC) microgrid studies related to a consortium

project on smart cities of the future.

The student will obtain deep knowledge in current

challenges of European electric grids.

The necessary balance between supply and demand is

in jeopardy due to the volatility of renewable energy

sources that is accompanied by the withdrawal of

larger conventional power plants from the grid.

Therefore, while the grid’s stability and reliability of

energy supply is challenged, load flexibilities and self-

sufficiency play a relevant role.

in order to enable new balancing mechanism for

smart energy systems.

With regard to higher shares of electric vehicles in

inner cities, the current electric grid has to be

equipped with more transformers and higher ca-

pacity on the lines in order to fulfill the electric

charging requirements.

Also, while the grid’s stability and reliability of en-

ergy supply is challenged, load flexibilities and

self-sufficiency play a relevant role.

Especially in urban areas, there is a high potential

of the so called “city batteries”: A large car park

for electric vehicles can be equipped with differ-

ent charging solutions (AC/DC and inductive

charging) and might provide ancillary services.

In 2018 the FEN Research Campus supports the devel-

opment of a pilot car park.

The student project is embedded in the context of stud-

ies related to the „FlAixEnergy“ consortium project, that

is funded by the Federal Ministry for Economic Affairs

and Energy (www.flaixenergy.de).

The student will face current challenges of electric

grids in Germany and the neighboring control sys-

tems: The necessary balance between supply and

demand is in jeopardy due to the volatility of re-

newable energy sources that is accompanied by

the withdrawal of larger conventional power

plants from the grid.

Energy-intensive loads from metal-, paper- and

pharmaceutical industries start to grow interest in

supporting the “Energiewende” by enabling load

flexibilities.

Corrosion is, the reaction of a material with its environ-

ment, which causes a measurable change in the mate-

rial and can lead to an impairment of the function of a

component or system.

Due to leakage currents in a DC-grid, an electrochemi-

cal corrosion can occur. Therefore, proper grounding

is required in the areas where a DC power system is

used. Within the work the given regulations have to be

reviewed and the key compensation methods should

be benchmarked.

which depend on the specific application environ-

ment. To evaluate the grid during the design process

eters for a building block are e.g. damping, control pa-

rameters for a DC/DC converter.

ulation.
