Monitoring and Energy Simulation Analysis of a Mechanical Workshop with Photovoltaic System and Electric Mobility Infrastructures Integration

The industrial sector is a significant part of the global economy, responsible for most energy consumption and worldwide emissions. In particular, mechanical workshops are very widespread in Italy; they are experts in the production, machining and marketing of precision engineering products. In this paper, an Italian mechanical workshop involved in mechanical production, has been studied. The electrical loads were monitored and analyzed over a period of four years and an energy model was developed to determine the electrical consumption of heat pumps used for the air conditioning of the building. The annual electricity production of a PV system installed on the roof was also analyzed. The annual trends were compared in order to assess the benefits achievable through the installation of a storage system. In the overall scenario of the company's electrification, an optimization model was also developed to determine the benefits to be gained from the implementation of electric mobility infrastructures: the optimal size of batteries and the number of EVs charging stations were determined based on the economic analysis.
