Energy and Economic Comparison of Virtual and Physical Power Sharing

In the actual energy transition scenario self consumption started to spread to support a more distributed generation and to contribute to the sustainable development, encouraging energy efficiency and promoting renewable energy sources. In Italy the virtual self consumption model is already regulated, but an important issue remains: defining the possibility of physically sharing electrical energy. In the paper, two different methods are presented and compared: one applying the Italian virtual self consumption model (Modello Regolatorio Virtuale MRV), the other one applying an innovative physical self consumption model (Power Sharing PS). This will be done by analysing the application to a real apartment building to see which method is the most convenient both from energetic and economic point of view.
