Investigation of the Behaviour of a New
Nanogrid Concept and the Nanogrid
Components
Ágnes Halász, Tamás Iváncsy, and Zoltán Ádám Tamus
Abstract In microgrids a distributed storage is efficient, but in the concept of microgrids the management of generation, storage and the flow between microgrids is
needed. The economical situation has to be taken into account also. Nanogrids are
smaller size of microgrids, but have the same main features. In an office environment
one office could be one nanogrid. We simulated the behaviour of the different components of the office nanogrid to obtain information about the possible time necessary
for charging and discharging a battery with given capacity. One possible extension
to the nanogrid concept is the use of Information and Communication Technology
(ICT) devices battery to extend the storage capacity. To optimize the charging of
ICT devices the battery management system (BMS) has to be extended with a software solution to obtain information from the state of the batteries. Simulations are
run to characterize the battery behaviour of ICT devices and its effect on the office
nanogrid. With the users calendar entries the software has to predict when the fully
charged state of the battery is expected, which also needs the charging times of the
different devices batteries. Further investigation is needed to show if this prediction
is also possible without the software part providing the battery state of charge.

31.1 Introduction
The main difficulty of electric energy distribution is the balance between the energy
production and consumption. Nowadays renewable energy sources have a big role in
electric energy generation but the balancing in such an environment is challenging.
Storage of electric energy is difficult, but it is a necessity. One possible way is to
convert the electric energy to DC and use some sort of rechargable batteries.
