CENER

The National Renewable Energy Centre (CENER) is a technology center, specialized in applied research and in the development and promotion of renewable energies. It has excellent qualifications and recognised national and international prestige.

The CENER-CIEMAT Foundation started its activity in 2002 and its Board of Trustees is comprised of the Ministry of Economy and Competitiveness, Ciemat (Research Centre for Energy, Environment and Technology), the Ministry of Industry, Energy and Tourism, and the Government of Navarra.

It currently provides services and performs research work in 6 areas: Wind,Solar Thermal and Solar Photovoltaic, Biomass, Energy in Buildings andRenewable Energy Grid Integration.

CENER has cutting-edge technological infrastructures, with the most modern laboratories and facilities in the world. The Wind Turbine Test Laboratory (the only one of its kind in the world), the Experimental Wind Farm, the 2ndGeneration Biofuel Centre and a Microgrid deserve a special mention.

CENER’s headquarters are located in the Ciudad de la Innovación, in Sarriguren, Navarra, although it has facilities and offices in other locations, such as: Sangüesa, Alaiz and Aoiz (in Navarra) and Seville.

The Renewable Energy Grid Integration Department aims at research and development of systems that lead to a greater and better integration of renewable energy into the electricity grid. This department analyses the possible problems that can occur in the electrical system due to a an increased penetration of renewables in the energy mix, proposing suitable management systems, including energy storage systems.

The areas of activity of the department are: High Voltage, Grid Integration and Energy Storage.

The Integration area focuses on solving and improving the problems arising from the integration of renewable energy into the electricity grid, combining theoretical studies with field tests.

This service provides technical assistance in:

  • Study of the behavior under transient phenomena and, in particular, to voltage dips. Simulations using specific software.
  • Distributed Generation - Electro-Thermal Smart Grids.
  • Design of microgrids.
  • Design control strategies for electrical microgrids.
  • Implementation.
  • Development of simulation models (hardware in the loop).
  • Integration of Storage Systems.
  • Study of Steady Flow and Dynamic Power System using specific software (PSS / E, DigSilent).

The Storage area is dedicated to the study and integration of energy storage systems as a fundamental solution for energy management, allowing greater integration of renewables into the grid.

This service provides technical assistance in:

  • Analysis of different energy storage systems.
  • Electrochemical Systems: Technologies Hydrogen, Flow Batteries, Conventional and Advanced Batteries.
  • Other: Flywheels, supercapacitors, etc.
  • Technical and economic viability analysis for the integration of energy storage systems and renewable. Development of the preliminary project design.
  • Analysis of the adequacy of storage systems.
  • Dimensioning and economic analysis of storage systems for different applications and management strategies.
  • Experimental studies in renewable energy facilities (wind and photovoltaic) including storage systems.
  • Virtual Storage and demand management.
  • Research and evaluation of energy scenarios in the medium to long term.
  • Development of models and simulation of renewable generation and energy storage.

Other projects:

Microgrid Atenea: Microgrids project funded by the Government of Navarra and FEDER funds. Installation of a microgrid in the Rocaforte industrial area in Sanguesa, Navarra. The microgrid allows to perform validation at both simulation and experimental through tests in real environment.

The National Renewable Energy Centre (CENER) is a technology centre, specialised in applied research and in the development and promotion of renewable energies.

The CENER-CIEMAT Foundation began its activities in 2002 and its Board is comprised of the Ministry of Economy and Competitiveness, CIEMAT, the Ministry of Industry, Energy and Tourism and the Government of Navarra. It is divided into six departments: Wind power, PV, Biomass, Bioclimatic architecture, Thermo solar and Renewable Energy Grid Integration (IRE) which participates in this proposal. The main goal is to increase and improve the integration of renewables into the grid and it has an extensive experience on distributed generation and smart grids. It is structured in two different areas:

  • Grid Integration Area develops activities such as:
    • Studies of distributed generation systems and smartgrids.
    • Analysis of the performance of machines and wind farms when faced with transitory phenomena and above all with voltage dips.
    • Power flow studies in stationary and dynamic regime.
  • Energy Storage Area develops activities such as:
    • Study of different Energy Storage Systems: Hydrogen technologies, Flow batteries, Conventional and Advanced batteries, Flywheel, Supercapacitors...
    • Techno-economical and Experimental Studies of Energy Storage Systems and Renewable Energies integration and stationary applications (households, campus, commercial malls).
