This thesis aims to develop an Intelligent Energy Management System (IEMS) specifically for buildings photovoltaic connected buildings in Sevilla, Spain, taking advantage on the region's solar irradiation. The primary objectives are to boost self-consumption of photovoltaic electricity, and reduce dependence on the grid by making real-time monitoring and predictive algorithms. Furthermore, a mobile application was designed to empower users in Sevilla to effectively manage their photovoltaic installations and energy consumption.
