COCOON (COoperative Cyber PrOtectiON for modern power grids) is a Horizon Europe Innovation Action (IA) project aiming to deliver a practical cyber-physical protection framework for converged Electrical Power and Energy Systems (EPES), targeting Technology Readiness Level (TRL) 7 and thus be evaluated against real operational setups. COCOON’s goal is to confront the on-going and evolving large-scale and stealthy threat vectors targeting the resilience of operational and mission-critical intra and inter-connected power grid deployments serving EU citizens. Hence, it aims to deliver a practical and unified systems solution to EPES operators by bridging secure networked systems research with software development and innovation with power systems engineering. Via an inter-disciplinary approach COCOON will address requirements of the recently released EU Agency for the Cooperation of Energy Regulators (ACER) Network Code for Cyber Security (NCCS) and the Smart Grid Architecture Model (SGAM) reference framework. The unified COCOON solution will be evaluated in real operational setups in Greece, Spain and the Netherlands and will benefit: (i) energy communities interacting with a Distribution System Operator (DSO), (ii) EU Regional Coordination Centres (RCC) interacting with multiple country-level Transmission System Operators, (iii) DSO substations, and (iv) Distributed Renewable Energy Sources (DRES) aggregators interacting with a DSO.
COCOON is built around five key objectives. First, it seeks to increase trustworthy information exchange between TSOs, DSOs, aggregators, and DRES deployments. This includes the development of secure, reliable communication protocols that ensure the integrity and confidentiality of inter-domain data. Second, it aims to implement a practical Early Warning System (EWS) that provides real-time threat detection and operator training capabilities, allowing EPES stakeholders to act proactively in mitigating cyber risks. Third, the project focuses on enabling real-time cyber-physical protection and grid stability by integrating OT-specific control and monitoring features with known IT vulnerabilities, offering a unified, cyber-aware operational perspective. Fourth, COCOON targets data-driven detection of both known and unseen zero-day threats in converged IT/OT environments using advanced analytics, machine learning, and OSINT-based threat intelligence. Fifth, it aims to strengthen the resilience of grid stability processes by improving coordination among EPES entities involved in Ancillary Services (AS)-based grid balancing operations, ensuring seamless operations even under cyber or system stress.
