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.
