A smart microgrid for buildings of the public administration

Abstract

An important share of energy consumption is due to buildings. Smart grids and Nearly Zero Energy Buildings are among key technologies towards more efficient and sustainable power systems. The present work is part of a project for the implementation of a smart grid connecting energy efficient buildings in the historical center of an Italian city. In this work, two public buildings are considered. First, the energy consumption of the buildings has been analyzed. Then, the refurbishment of the buildings, efficient thermal systems with heat pumps, local photovoltaic generation, cogeneration and electrical mobility infrastructure have been designed. Also, the possibility of connection of a multi-vector smart grid is investigated. The results show how the implemented system can increasingly contribute to the energy performance.
