“TECNALIA, CIRCE, ITI, ITECAM and AICIA combine their experience to respond to the strategic challenges of the electricity system”
Solutions for an interconnected electricity grid with a high penetration of renewables
TECNALIA is developing technological solutions aimed at transforming the electricity distribution network into an interconnected, flexible system that is capable of integrating high levels of renewable energy generation. Through the INTEGRID initiative, we are reinforcing our commitment to a more efficient, resilient network that is ready to meet the challenges of the energy transition.
More specifically, the main lines of research that we will focus on are:
- Voltage and frequency control algorithms embedded in power plant controllers (PPCs) for hybrid renewable energy plants.
- Managing flexibility and adding distributed resources for distribution system operators (DSOs) and markets.
- Hybrid storage models and management for active and passive components.
- Tools and models for the advanced operation of the low-voltage electricity grid.
- Advanced power line communication (PLC) to be able to monitor the network more effectively.
- Network analysis and modelling to optimise protection systems.
The Cervera INTEGRID Network in response to the challenges of the electricity system
The Spanish electricity system is facing critical challenges resulting from the massive integration of renewable energy sources, the growing difficulty in forecasting generation and demand, and grid overload. In response to this situation, the Cervera INTEGRID Network has brought together CIRCE, TECNALIA, ITI, ITECAM and AICIA with the aim of strengthening their scientific and technological capabilities and developing innovative solutions to improve distribution efficiency, the secure integration of renewables and storage, and system stability.
Their work is based around five key areas:
- Control and management of renewable plants.
- Network operation and planning strategies.
- Reinforcement and transformation of the distribution infrastructure.
- New roles for storage.
- Digital enabling technologies.
This project was funded by the Ministry of Science, Innovation and Universities, and promoted by the Centre for Technological Development and Innovation (CDTI) through the CERVERA Programme for Technology Centres (file CER-20251033, 2026-2028).
This line of work is directly aligned with the CERVERA technology: “Technologies and systems for improving the efficiency of energy distribution”.
