The new concept of renewable energy communities introduced by the Revised European Directive on the promotion of renewable sources (2018/2001) has opened new possibilities for microgrids. In fact, it permits to enhance the value of the energy produced by renewable sources sharing it inside an 'energy community' and to increase the social welfare. In this article, the authors investigated about the actual legislation framework on energy communities at the European and Italian level, highlighting regulatory problems and barriers that are delaying their constitutions.

This paper investigates the feasibility of a recently proposed building energy community scheme where the energy of a single rooftop photovoltaic system is shared by costumers with a open and democratic participation. A Simulink/Matlab model is developed where we focus on the implementation and control aspects of all the relevant components, e.g., voltage source inverters for ac grid connection, dc/dc converter with maximum power point tracking strategy, inverters control for energy sharing among end-user.
