DERlab has started workshop series on special technical topics concerning the development of smart grids aiming at a harmonised European approach.

3rd DERlab Workshop Series in Progress
"Grid-Interfaces of Storage Systems"
Grid-connected Storage Systems are one important element to massively integrate distributed renewable energy sources, which are typically intermittent, into the power system.
|
| The first workshop of this series took place in Prague on June 11, 2009 in conjunction with the CIRED conference. |

2nd DERlab Workshop Series in Progress
"Harmonised Interconnection Requirements for DER"
The absence of a harmonised interconnection standard has been identified as one of the most severe obstacles towards the wide deployment of DER and as a result to the change towards active electricity networks. Addressing this diversity has been set as one of the most important objectives of the research community. Thus it is also one of the key objectives of DERlab. As a first step for harmonisation DERlab proposed a structure for a European Standard for interconnection of Distributed Energy Resources (EDIS).(Click here for more details.)
DERlab contributes actively to the recently created working group (WG 03) of CENELEC/TC8X, dealing with the formulation of the technical specification "Requirements for the connection of generators above 16 A per phase to the LV/ MV distribution system".
The 2nd DERlab workshop series will support this standardisation work.
The first workshop of this series took place in Rome on March 3, 2009, with participants from the CENELEC TC8X work group 3 and the DERlab network. The discussions gave input to the following CENELC work group meeting.

|
The second DERlab Workshop on Harmonised Interconnection Requirements for DER was held on the 13th of May 2009 in Salzburg, Austria.
|
|
The objective of this workshop was to bundle existing standardisation activities with the objective of harmonising European grid connection requirements. With almost 20 participants covering all the types of organisations concerned by DER interconnection requirements (network operators, manufacturers, research institutions, ministries), this workshop allowed participants to exchange up-to-date information on current standardisation activities and reinforced the discussion process on the most topical issues (e.g. contribution to voltage control and fault ride through).
The presentations are available for download here.

Report on the 1st DERlab Workshop Series: 25/06/2008, 17/09/2008, 09/12/2008
"International White Book on the Grid Integration of Static Converters"
|
|
The European Union set a binding target for 20% of the EU's total energy supply to come from renewables by 2020.(Click here for more details.)
The resulting high penetration rate of distributed renewable energy sources, which are typically intermittent, will affect the electricity power system. Grid inverters are the key elements to massively integrate distributed renewable energy sources into the power system. Aim of this series of workshops is to define common European requirements for the grid inverter of the future.

Developing an European vision step by step
This series of workshops has been initiated as a result of an international discussion at the DERlab workshop on "DER laboratories of Excellence, Testing, and Standards" that was held at the "2nd International Conference on Integration of Renewable and Distributed Energy Resources" in Napa, California, Dec. 2006.
1st DERlab Workshop on Grid Inverters combined with the CIRED 2008 Seminar on Smart Grids for Distribution
The first "DERlab Workshop on Grid Inverters" took place in Germany, Frankfurt on June 25, 2008 in connection with the CIRED Seminar 2008 on smart grids for distribution. It was the kick-off for writing the "International White Book on the Grid Integration of Static Converters". With more than 50 participants from universities, DER test laboratories, distributed system operators and industry it shows the high relevance of this issue to the scientific community and the industry.

2nd DERlab Workshop on Grid Inverters combined with the 13th Kasseler Symposium Energy Systems Technology - Power Converters in Grids
On the second DERlab workshop the chapter editors presented the first draft of the "International White Book on the Grid Integration of Static Converters". In parallel sessions the workshop participants pictured their visions 2020 for the tasks of static converters in distribution grids. Now the draft European white book is in the process of elaborating and editing.
This European draft was then discussed on international level during the third DERlab workshop, which was held before the "3rd International Conference on Integration of Renewable and Distributed Energy Resources" in Nice, December 9, 2008. The comments especially from the participants from the US and Canada were highly welcome.

Drafting the white book
The outcome of the workshops are currently compiled and edited. The following drafted chapters are available already:
First draft chapter 1: Ancillary Services (slides)
(improvement of power quality, balancing power, demand side service,...)
Chair: Prof Hanzelka, TU Lodz, Poland
First draft chapter 2: Behaviour under fault conditions (drafted text) (slides)
(fault-ride-through, loss-of-mains, network restoration, network protection,...)
Chair: Dr Thomas Degner, ISET, Germany
First draft chapter 3: Communication, control and energy management (slides)
(communication protocols, bi-directional communication, grid monitoring, VPP, operation modes and their management strategies,...)
Chair: Dr Takis Romanos, NTUA, Greece and Dr Jens Merten, CEA INES, France
With this white book as working paper for the inverter specialists we want to achieve a consensus as broad as possible. Your participation is welcome, too. So please download the drafts and contribute to this work by sending your comments to info@der-lab.net.

DERlab workshops
To discuss the elaborated long term inverter requirements on a broad basis and to account for different points of view across Europe regional workshops are planned. See regional events for more information.
