Description
Located in the province of Soria, twenty kilometres away from the provincial capital, the Centro de Desarrollo de Energías Renovables (Renewable Energy Development Centre – CEDER) covers an expanse of 640 hectares, with over 13,000 m2 of constructed space, housing laboratories, administrative and general offices, pilot plant units and warehouses.
 
The Centre depends on the Centro de Investigaciones Energéticas, Medioambientales y Tec-
nológicas (Energy, Environment and Technology Research Centre – CIEMAT) and took its first steps 25 years ago working on research projects linked to renewable energy generation sources. It is currently assigned to the Energy Department of this Public Research Body, wi- thin the State Secretariat for Research, Development and Innovation of the Ministry for Eco- nomy and Competitiveness.
 
CIEMAT, in line with its priority of developing renewable energy, is promoting research acti- vities at CEDER, taking advantage of the Centre’s human potential and the opportunities it offers for housing demonstration plants. The Body’s Strategic Plan (as part of the Spanish Government’s Strategic Plans for Public Research Bodies – National Plan for Scientific Re- search, Development and Technological Innovation 2004-2007) already envisaged the rein- forcement of CEDER in Soria as one of its specific objectives. The real goal is to strengthen CEDER’s current capabilities and turn it into a reference centre for clean technology, parti- cularly focusing on wind power and energy assessments of biomass and waste. In addition to renewing its current infrastructures, the plan also seeks to encourage the commissioning of projects in which other centres and institutions play a significant role.
 
The present European framework for research projects shows a clear focus on the field of smart grids and elec- tricity, particularly microgrids, which are of even greater interest if they are able to integrate distributed genera- tion through renewables as well as all of the new agents that have gradually come up and will be defining the grids of the future.
 
Along these lines, CEDER-CIEMAT has promoted and strengthened its facilities in Lubia, Soria; an infrastruc- ture that comprises a series of electric and thermal loads (wind power, photovoltaic energy and biomass) and storage elements (Lead-Acid batteries and Ion-Li- thium batteries). These facilities have been granted con- siderable flexibility and are able to operate in different ways with different configurations, meaning they can adapt to the requirements that must be demanded of a “test  bench”.
 
 
Services offered
 
The entire infrastructure available (MV and LV electric systems, transformation hubs, end consumption, generation sources, communication elements, etc.) all belongs to CEDER-CIE- MAT, making this the perfect scenario to test and try the performance of “Smart Grid” and “Microgrid”  projects.
 
The type of electric grid, its voltage levels (MV or LV), its variety of real loads (diffe- rent buildings with different profiles: industrial buildings, offices and so on) and its sources of renewable genera- tion and storage mean it is ideal for intermediate tests between a small-scale labo- ratory and final deployment of the real product.

OTHERS

CEDER also has district heating by means of heat generation machines (biomass), enabling its buildings to behave as both producers and consumers of heat.
 
This infrastructure makes it possible to integrate heat as part of the microgrid and to test new heat generation technology.
 
 

PROJECTS

Projects carried out on the microgrid. Below is a list of some of the projects performed in the different laboratories or living labs at CIEMAT:
  • CICLOPS II: CIEMAT is working on designing new wind turbines within the field of ae- rodynamic and structural blade design. It is collaborating with national and foreign ma- nufacturers on the development of small wind turbine tests and on the appraisal of isolated systems using wind power, especially the new hybrid wind/photovoltaic/diesel CICLOPS II system, developed experimentally at CEDER’s Small Wind Turbine Test Plant II (PEPA II).
  • SEDUCTOR: Regarding power electronics and simulation, work is being continued on the project to develop a kinetic energy storage system (SEDUCTOR project) for wind power. The maximum forecast speed of 30,000 rpm has been reached and the production of a 50 kW, 4.8 MJ storage is about to be completed.
  • SINTER Project - Intelligent Grid Stabilising Systems: Integration of storage based on hydrogen technology using wind power. The main technical goal of this project is to de- monstrate the utility of storage integration based on hydrogen technology, using wind power in order to stabilise weak or overloaded ends of the grid, and to integrate renewable energy using grid stabilising functions, which would enable work while connected to the grid or in isolation. INNPACTO (national project).
  • GEBE Project - Power Grid Balance Manager with Smart Distributed Generation. The main goal here is to design, construct and test a smart system for management of energy grids that are interconnected through the electric grid, the aim of which is to optimise power flows according to financial criteria. INNPACTO (national project).
  • Design and development of software for the organisation and smart regulaion of energy management in city councils: acronym S.O.R.I.A. (+ x -). The aim is to provide municipal public administrations with a tool that will enable them to plan and implement measures that seek to influence the way energy is consumed in the area of public services and bring about the desired changes in the demand curve. INNPACTO (national project).
  • MIRED-CON: Distributed Renewable MIcrogreneration/MInigeneration and CONtrol thereof. This consists in installing an infrastructure for advanced measurement and control over a grid that seeks to manage its own energy, turning this new grid into a reference point for what the distribution grids of the future could be like.
  • Virtual Microgrid Operator for storage: OVI-RED. The idea with OVI-RED is to design, de- velop and implement a system for joint microgrid management. These microgrids will, in turn, individually manage the resources contained within their local microgrid, using dis- tributed energy storage with varied technology, energy capacities and manageability. Here, the concept of VPPs (Virtual Power Plants) is the main basis.
  • INNDISOL project. CIEMAT is collaborating with the Carlos III University on this project,
  • which comprises 10 mini photovoltaic plants with different types of technology (1 kW per plant).
  • ACEBO (Low Cost Kinetic Energy Storage). With this project, the aim is to design, develop and construct a full energy storage system based on the inertia flywheel, especially desig- ned to be applied in the field of renewable energy, and particularly in weak grids.
  • Projects related to solar photovoltaic with the involvement of CIEMAT include: ERA-NET; ULTRA OPV; HEROI; Plug and Play; BIPV.
  • GELSHI: Generation of clean energy using hybrid systems. CIEMAT. (Internal, non-funded project). This is a clean energy generation system that uses an 80 W peak photovoltaic panel and a wind turbine with a maximum generation capacity of 500 W as energy sour- ces, as well as a 500 W PEM fuel cell fed on hydrogen. The system’s design enables it to operate in three different modes: savings mode, constant charge mode and variable charge mode.
  • DIVERCEL: Energy diversification using generation systems based on fuel cells. Commu- nity of Madrid, S2009/ENE-1475. Efforts here are focused on both scientific research —fuel cells, hydrogen production using renewable energy sources— and on technological development, integration, prototypes and demonstrators that will simplify the process of transferring this technology to other industries that are committing to implementing new technologies.
  • DOTGe: Demonstration and optimisation of technology for biomass gasification on bub- bling fluidised beds. Demonstration on an industrial scale of electric power generation technology based on biomass gasification, and optimisation of said technology from a fi- nancial, energy and environmental perspective.
  • SA2VE (Advanced Energy Storage Systems). Unique scientific-technological projects of a strategic nature for 2007-2012. The aim of the project was to develop kinetic storage technology for different applications. Specifically, CIEMAT’s work focused on two main points: developing the kinetic storage system (including power electronics and advanced control techniques); and applying stationary energy storage to railway transport (substa- tions).
  • SOFC-BIO: “Efficient anodic materials for IT-SOFCs fed on biogas; a renewable fuel. Mi- nistry of Science and Innovation. The main aim of this project is to develop new anodic materials for SOFCs that can run on biogas as a fuel at an intermediate temperature (600- 800 °C) and to apply these materials to electric energy generation.
  • ELECTROFILM: Preparing and studying thin micro-porous films for electro-chemical energy conversion in fuel cells. This project takes an in-depth look at the basic aspects of methods for electrode manufacturing deposition, electro-deposition and electro-pulveri- sation, seeking to apply these methods in the preparation of films for PEMFCs. These films will essentially be made up of the electrode components contained in this type of battery cells; i.e., the gas diffusion layer and catalyst layer, and catalysed membranes. Thus, the aim is to optimise their properties for electro-chemical reaction, which causes oxygen reduction while the PEFMC cathode is in working conditions.
  • Energy management in railway substations for electric vehicle charging supported by re- newables. The goal of this project is to add the functionality of electric vehicle charging to a system implemented within Madrid’s Cercanías (suburban rail) network as part of the SA2VE project. The system as a whole includes kinetic energy storage, ultra-capacitors, photovoltaic cells, two-way connection with the DC overhead power cables of the Cercanías network and electric vehicle charging systems. This project is also working on a functio- nality to manage the entire system’s energy in the event of unstable loads.
  • Train2Car. The aim is to develop energy management systems for Madrid’s Metro (under- ground) network to respond to the inclusion of electric vehicle charging systems and energy storage systems. This will done using ultracapacitors and by implementing traffic mana- gement and signalling within that network.
  • INNDISOL project. Developing the above strategy is precisely the focus of the INNDISOL project, which has the following objectives: a) increasing the efficiency of thin-film, sin- gle-joint silicon modules; b) generating all the technology necessary to manufacture multi- joint silicon cells; c) encouraging the development of semi-transparent modules, both of thin-film silicon and of multi-joint silicon; and d) promoting the development of photovol- taic elements integrated inside buildings.
  • H2RENOV project. The main objective of the project is to develop efficient and competitive hydrogen production technology that will enable the implementation of a hydrogen eco- nomy in Spain based on local renewable energy sources. This will help place Spain at the cutting edge of knowledge and will promote a highly competitive sector

Future plans

The centre is being equipped with the necessary hydraulic systems to support a Pelton tur- bine with an asynchronous three-phase controllable generator, with a power output of ap- proximately 50-60 kWe, a net waterfall of 60 m and a delivery flow of 120 l/s. Currently installed is a polyethylene hydraulic pipe with a 220 mm internal diameter. The centre is fitted with parallel fibre cement channels and hydraulic pumps (two pumps of 21 CV each) so that both systems can ensure turbine or pumping activity, according to strategy.
 
The idea is to provide one of the inertia flywheels developed by CIEMAT and integrate it in the CEDER tests. To do so, the system must be adjusted to the grid it is going to be attached to. Therefore, the plan is to develop an electronic converter for connection to the grid, a remote platform to control the system via IP and a strategy for joint operation with the rest of the local network. The device under development by CIEMAT has 25 kW of power, 6 minutes autonomy at full power (9 MJ), a maximum speed of 13100 rpm, a module weight of 900 Kg approx., and the following outer measurements: base 700x700 mm, height 800 mm (provi- ding the system with the maximum pressure).
