Optimizing renewable energy communities through ontology-driven energy management systems

The ongoing digitalization of the energy system is a key enabler for the clean energy transition, but it also leads to fragmentation of platforms, protocols, and standards. The PARMENIDES project addresses these challenges by developing an ontology-based Energy Management System for the utilization of Hybrid Energy Storage Systems. This system leverages the so-called PARMENIDES Energy Community Ontology (PECO), which provides a unified vocabulary ensuring semantic interoperability across data models and information layers within Renewable Energy Communities (RECs). PECO formally describes key aspects of energy communities, including methods for excess energy allocation, internal energy pricing mechanisms, and the relationships among community members and their assets. The project demonstrates its solutions in diverse pilot projects in Austria and Sweden. The Austrian pilot emphasizes Renewable Energy Communities with automated asset optimization, while the Swedish pilot focuses on short-term flexibility and innovative control strategies. By integrating various storage technologies and optimizing their use, the project aims to enhance the resilience and sustainability of energy systems, contributing to the broader goals of the clean energy transition.
