Summary:

This work offers an overview of the essential findings of the project OneNet, which aims to enable a pan-European electrical system where the heterogeneous landscape of stakeholders, markets and platforms across Europe can openly participate at all levels. The paper outlines the vision for an interoperable open-source and open-access architecture, which enables the full exploitation of flexibilities in the energy system by maximizing the integration of distributed resources and end customers enabling interaction and coordination among all stakeholders. The paper addresses the aspects harmonization, interoperability, technical background of the implementation of the reference architecture, as well as cybersecurity.

Spanish layman's summary:

El artículo presenta la visión de OneNet para un sistema eléctrico paneuropeo, centrada en armonización, interoperabilidad y una arquitectura abierta que facilite la flexibilidad, los recursos distribuidos y la coordinación entre agentes.
