Background: The scope of this paper is to study the energy trading in microgrids. Microgrids
are low voltage or medium voltage distribution networks, which consist of energy storage
systems, electric loads, e.g. electric vehicles and Renewable Energy Sources (RES).
Methods: Legacy energy grids are being transformed by the introduction of small to medium sized
individual or cooperative, mostly RES invested energy producers and prosumers. Electric vehicles
penetrate the market and modern power grids integrate them as ancillary services providers when
there are peak domestic loads, as well as in order to balance grid voltage aiming to increase system
reliability, compensating for renewable energy sources’ intermittency and volatility in energy production.
Results: An elaborate management algorithm is proposed in this paper, to balance demand and local
renewable energy sources microgrid supply.
Conclusion: Finally, the results of simulations of different scenarios, including economic parameters
and proposals for future research are presented.
