The main objective of project e-GOTHAM is to implement a new aggregated energy demand model (based on the microgrid concept) in order to effectively integrate renewable energies sources, increase management efficiency by dynamically matching demand and supply, reduce carbon emissions by giving priority to green energy sources, raise energy consumption awareness by monitoring products and services and stimulate the development of a leading-edge market for energy-efficient technologies with new business models.e-GOTHAM will define a complete solution for microgrids in the residential, tertiary and industrial sectors that include different configurations of loads, distributed generators and energy storage components.To carry out the e-GOTHAM concept, the project will design an open architecture and develop a middleware that enables the needed communications for management and results optimisation.The challenge of the middleware produced in e-GOTHAM is to assemble a system which can ensure enough scalability, security, reliability, real time measurements and interoperability so as to lead to the development of a large-scale embedded systems network, a smart data management model, a set of models and algorithms that dynamically correlate energy-related, pollution-related, cost-related and behaviour-related patterns and a just-in-time adaptive communication model that interoperates different protocols to support seamless connectivity across the microgrid.e-GOTHAM is a market-oriented project that seeks to meet the needs of the involved market partners, especially power producers and microgrid owners, and to have an influence on consumers and on the authorities who define regulations.Finally, e-GOTHAM aims at creating an ecosystem meant to attract those relevant stakeholders who are willing to elaborate on project results so as to generate new products and services and to support the looked-for new aggregated energy demand model even beyond the project lifetime.This TA was approved by the ECSEL Joint Undertaking on 22/04/2015.
