Research, definition and development of a comprehensive Smart Planning and Operation System for energy communities based on digital energy tokens and the evolution of Artificial Intelligence based optimisation modules. The CENIT2.0 digital platform is designed as a Software as a Service (SaaS) accessible from anywhere and at any time. The architecture of the system is based on a division into layers, each of them with a well-defined role within the digital transformation of energy communities: (i) graphic interface and user experience layer, where the user interacts with the system; (ii) service provision layer to end users according to the different usage scenarios proposed; (iii) Data and API architecture layer; (iv) Smart layer that brings together the functional logic of the system divided into different modules: Smart planning module based on Artificial Intelligence for the detection and estimation of roof surfaces, module for hierarchical and distributed operation of the energy community in order to maximise energy efficiency and, finally, an energy exchange module based on the complete digitalisation of energy as an asset (tokenisation) to guarantee traceability, security and reliability of all energy exchanges within the system through Smart Contracts, encouraging the development of new applications around energy that represent added value.
