Effective Substation TEchnoLogies for Advanced viRtualization

The ESTELAR project is dedicated to modernizing power grids to accommodate renewable energy sources and enhance energy efficiency, focusing specifically on the virtualization of substations to improve the grid's sustainability and resilience. By redefining the operation and concept of substations—key components within the power grid infrastructure—ESTELAR aims to facilitate the energy transition towards carbon neutrality.ESTELAR is based on three innovative pillars: advanced communication strategies, a robust computational framework, and the transformative Digital Substation of the Future architecture. The first pillar focuses on enhancing substation communication systems to facilitate seamless and real-time integration of physical and virtual components. The second pillar aims to boost the processing and data handling capabilities of substations across both cloud and edge computing platforms for future computational demands. The third pillar is centered on developing a modular and scalable substation architecture that incorporates advanced monitoring, protection, and control through digital twinning.To ensure the efficacy and readiness of these technologies, ESTELAR will conduct rigorous validations in two Virtualization Testing Laboratories located in Spain and The Netherlands. These facilities will allow for realistic, controlled testing environments to refine and perfect the technologies prior to widespread implementation.The project unites nine partners from four EU countries, combining expertise from research centers, technology providers, and distribution system operators to comprehensively approach substation virtualization. ESTELAR facilitates renewable energy integration, bolsters grid resilience, and supports wider electrification. This positions it as a key player in accelerating the EU's transition to a climate-neutral economy.
