The evolution of the challenges linked to climate change and the growing energy demand have driven the adoption of innovative approaches in the energy sector. Renewable energy communities (RECs) emerge as a permanent solution, allowing the production, distribution, and consumption of electricity from renewable sources at a local level, downsizing the electricity distribution network and reevaluating the concept of locality, community and energy efficiency. This master's thesis focuses on the design and optimization of such communities by means of a software written in Python that exploits algorithms and automation approaches in order to reduce working time and simplify the overall process.Throughout this work, the following key areas were explored: ●??Design of the energy production plant from renewable sources, specifically photovoltaic technology.
