Description
IREC’s microgrid is a low-voltage, 200 kVA system made up of several different types of ge- neration, storage and consumption units. It is a lab-level platform intended for researching the challenges and technological solutions linked to microgrids:
  • Demand management algorithms.
  • Advanced communication protocols (IEC 61850).
  • Power electronics for connection to renewable sources.
  • Battery and supercapacitor technology.
  • Supporting grid stability in the event of certain disturbances or variations.
  • Managing electric vehicle charging (and discharging).
  • Smart and two-way protection.
  • Smart meters.
  • Advancedmeasurementtechnology:PMUs.
  • Communication means and technology: PLC, radiofrequency…
IREC’s microgrid comprises:
 
  • A grid emulator (200 kVA).
  • An Ion-Lithium battery (5 kVA). l A supercapacitor stack (5 kVA). l Emulation systems (5 x 5 kVA).
  • Slow electric vehicle charging points (2 x 3.7 kWh, not currently installed).
  • An inertia flywheel (4000 rpm, 5 kVA).
  • Engine-generator benches (3 x 5 kVA, 1 x 30 kVA).
  • An urban wind turbine (2 kW, not currently installed).
  • Photovoltaic panels (5 kW, not currently installed).
 
The emulation systems are stationary converters capable of reproducing the electrical beha- viour of variable generators (such as wind turbines, photovoltaic panels, etc.), consumptions or storage systems without having to use forms of energy other than electricity.
 
 
All of the systems in the microgrid are connected to a 200 kVA grid emulator in which the voltage at the point of connection between the microgrid and the distribution grid can be modified and the different aspects of the grid can be analysed, including:
  • Harmonics control and generation
  • Voltage dips
  • Flickers
  • Non-symmetrical voltage generation
  • Frequency variations
 
In order to manage the microgrid and test different control strategies (centralised/distributed, primary/secondary), an architecture has been developed based on iSockets and iNodes. These elements are control cards that are capable of communicating. Each system is managed by an iSocket. iSockets are, in turn, managed by an iNode, which then receives orders from another agent designated by the Microgrid Control Unit (MCU). Communication between iSockets and iNodes occurs as per IEC protocol 61850.
Services offered
 
The IREC microgrid offers two types of services:
  • Smart grid and microgrid testing platform: Implementing research and technology transfer projects in order to validate smart grid and mi- crogrid solutions prior to their im- plementation in the field. Solutions include: microgrid management al- gorithms, integration of renewa- bles, electric vehicle impact and functionalities, control systems, microgrid protection, communica- tions and so on. The projects are carried out using the facility’s own equipment or, alternatively, exter- nal equipment.
  • Platform for developing electrical equipment or systems for Smart grids and microgrids: The microgrid is used as an infrastructure in which to conduct trials and tests on electrical equipment or systems in order to integrate them into the grid or microgrids. Systems in- clude: power inverters/converters, renewable generation systems, storage systems, electric vehicle charging systems, and communication and management systems.

OTHERS

Flexible and modular platform: Connection of the systems to the microgrid is made through electrical boxes supported by conduction busbars suspended from the ceiling. The chests can be extracted and connected safely at different points of the busbars, which is useful for modifying the typology of the microgrid according to the project or test to be carried out.

  • SmartCity Living Lab. This was the first microgrid project at IREC. It involved using three emulation cabinets that were configured so as to emulate a general microgrid scenario, with generation, storage and consumption. A management algorithm was developed to boost the minimal amount of informa- tion exchanged between iNode and iSockets. It was also the first project in which IEC 61850 was applied.
  • DER–IREC 22@ Microgrid. Five emulation cabinets were used. They were configured so as to emulate a hotel scenario with variable generation, variable consumption and storage. It was tried on a microgrid management algorithm and used a commercial SCADA system (http://der-microgrid.gtd.es/).
  • Charge & Ride. Developing and implementing the control algorithms that manage break power in trains for the purpose of electric vehicle charging within a railway network.
  • NOVARE 09 Awards: Vehicle to Microgrid. Testing the applications at two-way electric vehicle charging points (Vehicle 2 Grid, V2G) in a domestic microgrid. Power is managed from a system operator’s standpoint and a domestic user’s perspective.
  • Green eMotion. Management of electric vehicle battery charging and discharging within a microgrid once their useful life as part of a vehicle has ended (second life) (http://www.greenemotion- project.eu/). Designing and implementing management algorithms for microgrids and Medium Vol- tage multi-microgrids.
  • EMERGE. Developing and implementing control for the 9-phase generator and the converter for a 30 kVA engine-generator. Control will be tested against voltage dips and other disturbances in the grid.
  • KIC InnoEnergy Project ‘MTT Micro CHP’. Dynamic testing of a co-generation micro wind turbine in real conditions (emulating using different electrical and thermal consumption profiles and weather conditions).
 
 

Future plans

  1. IREC’s microgrid was born as a pioneering experiment platform for smart grid develop- ment in Europe. To fulfil this aim, the IREC is planning to broaden its capabilities in the fields of electrical supply quality, renewables and operating in isolation.
  2. In the mid term, there are plans to transfer and extend IREC’s microgrid to the new premises on the Campus Diagonal Besòs in Barcelona’s Energy Park.
  3. As regards microgrid connection and management, IREC’s microgrid in Barcelona and the IREC SEILAB in Tarragona will be connected by a real HV/MV grid
