DA/RE project: first retrievals of redispatch capacities

11.07.2019

The Baden-Württemberg grid security initiative “DA/RE” (“DAta exchange/REdispatch”) addresses the increasing volatility and decentralisation of power generation. The aim is to stabilise the entire electricity system by utilising the flexibility potential of decentralised generation units from lower grid levels. Originally launched in the summer of 2018 by TSCNET shareholder TransnetBW, the German transmission system operator (TSO) from the state of Baden-Württemberg, and the southwest German distribution system operator (DSO) Netze BW, the project consortium was later expanded so that a total of three DSOs and four other partners from the areas of virtual power plants, home storage and energy trading were involved in the first DA/RE pilot phase from April to June 2019.

During this phase, the participants have defined and developed the method of data exchange and coordination. Following this successful implementation process, the first retrievals from pilot plants in the distribution network for redispatch purposes have now been initiated. Capacities were retrieved from battery home storage facilities, several biogas plants, a waste incineration plant and a cogeneration plant. The tests therefore involved both medium-voltage and low-voltage systems and the project partners have demonstrated that it is possible and important to make use of all flexibilities at all voltage levels for grid stabilisation.

“The retrievals from systems in the distribution network constitute a significant milestone for us, as they show that the concept is feasible and we are now able to gain initial experience in terms of practical suitability,” explains DA/RE project manager Florian Gutekunst from TransnetBW. The second stage of the pilot phase has thus begun. Further retrievals are now being carried out and various application cases are being tested. In concrete terms, the issue is how grid operators can trigger the retrieval of redispatch measures in a coordinated manner and how the information chain should be designed in order to guarantee all parties involved at all voltage levels complete transparency about the retrieval and the capacity provided. In the following third step, the retrievals are to be automated and the corresponding data paths implemented.

Retrospect on Innogrid2020+

15.05.2019

This year’s Innogrid2020+ took place in Brussels on 13 and 14 May. Jointly organised by the European Network of Transmission System Operators for Electricity (ENTSO-E) and the European Distribution System Operators for Smart Grids (EDSO), the motto of the prestigious annual event for 2019 was “Connecting Physics and Digits: Power Platforms on the Rise”. So, it was about physical networks and their permeation with information and communication technologies, transforming the energy system into a cyberphysical system. Among the presented projects during Innogrid2020+ were several, in which TSCNET shareholders participate: “Crossbow” with Croatian transmission system operator (TSO) HOPS, “DA/RE” by German TSO TransnetBW, “FutureFlow” (ELES from Slovenia, APG from Austria, MAVIR from Hungary, and Transelectrica from Romania), “MIGRATE” (Amprion from Germany, ELES, and Dutch-German TSO TenneT), and SINCRO.GRID (ELES and HOPS). Besides, Yves Zumwald, CEO of Swissgrid, took part as speaker in the “CEO business track panel on innovation”.

In addition to informative sessions on disruptive technologies, innovation policy or targets for 2030, the event hosts also presented the 2nd European Power Network Awards during Innogrid2020+. The first winner is the Signposting Information project by the British Distribution System Operator (DSO) WPG, which aims to open new neutral markets around flexibility. The second winner is the digital platform “cyberNOC” by CyberGRID, a specialist in the development of virtual power plant solutions. cyberNOC stands for the seamless and secure integration of battery energy storage systems and electric vehicles with aggregators, electricity markets, and grid operators.

On the second day of Innogrid2020+, ENTSO-E and EDSO used the public interest in the event to present six recommendations on energy network innovation to the European Commission in the forefront of the Copenhagen Energy Infrastructure Forum on 23 and 24 May. These recommendations include the promotion of TSO-DSO cooperation, adequate support for research, development and innovation, of sectoral coupling and digitisation, or the linking of EU funding programmes.

DA/RE enters pilot phase

02.04.2019

Following its launch in June 2018, the Baden-Württemberg grid security initiative “DA/RE” (“DAta exchange/REdispatch”) has entered the pilot phase on 1 April. The DA/RE initiators are TSCNET shareholder TransnetBW, the German transmission system operator (TSO) from the state of Baden-Württemberg, and the southwest German distribution system operator (DSO) Netze BW with the support of the State Ministry of the Environment, Climate Protection and the Energy Sector. Meanwhile, several grid and facility operators are involved and actively participating in the pilot phase.

DA/RE responds to the increasing volatility and decentralisation of power generation. By utilising the flexibility potential of decentralised plants from lower grid levels, the entire electricity system is intended to be stabilised. Basically, DA/RE is an IT platform, through which grid operators can obtain information on flexibility potentials and coordinatedly retrieve them. In the trial phase, scheduled to last until the end of September 2019, two essential modules for data exchange and coordination between grid and facility operators are to be tested.

With its wide range of decentralised systems, DA/RE adequately represents the current market for flexibility. “Together we can thus test the processes with different DSOs up to medium voltage level and provide the further course of the project with valuable experience,” explains Florian Gutekunst, DA/RE project manager at TransnetBW.
