This dissertation was written as a part of the MSc in ICT Systems at the International
Hellenic University. The topic of this paper is concentrated on the power grid and how it
can be modeled when a small group of prosumers exchange electricity among themselves.
First we elaborate how the smart grid 3.0 works and its evolution from the smart grid.
Here we concentrate on the architecture of the previous versions of the smart grid, as
well as the role of ICT and renewable sources of energy (solar, wind). Next we explain
the architecture of the entities of the contemporary smart grid, such as microgrids, virtual
power plants, prosumers and transactive energy markets. In the last part of this chapter
we explain the energy market, and its evolution from monopolized market to a deregulated
market. The operation of electricity exchange on a wholesale and retail level is
explained at this point.
In chapter 3 we elaborate the prosumer scenario we have developed by first starting with
describing game theory in general. Next we explain the Shapley value and how we can
use that model to allow users in our scenario to collaborate among each other and exchange
electricity for benefits. We propose our solution and explain our findings. Next
we propose a schematic model of distributing the remaining electricity to the grid by
using again the Shapley theorem.
Here I would like to express my gratitude to all the people that helped me to accomplish
this master course and have an amazing year:
First I would like to thank the university course office, who made me feel welcomed and
helped me with all my issues and questions I had during my studies.
I thank our professors, who thought me so much in a short period of time, particularly
my supervisors prof. Meo and prof. Koutitas, for giving me the opportunity to work
with them on this dissertation. Special thanks to prof. Koutitas, for his guidance, patience
and motivation, it made me believe in me much more.
I thank my family, for their patience and support during this whole process.
And last but not least, my colleagues, thank you we had amazing times.
Special thanks to Terezia and Pannikos, you made those long study nights much more
