“RiffReporter” story: The more precise the forecast, the less intervention is required

11.12.2018

A detailed article by freelance journalist Daniela Becker on the German reportage website RiffReporter, an innovative and award-winning project for “quality journalism on future topics”, presents TSCNET Services and the work of a Regional Security Coordinator (RSC) for the European power transmission grid. The article is based on thorough research and a talk with the two TSCNET managing directors, Maik Neubauer and Uwe Zimmermann. Besides the development of the company, the possible consequences of the EU package “Clean Energy for All Europeans” are also discussed.

“E&M Powernews”: “Excellent overview of the grid”

27.07.2018

Largely unnoticed by the broad public, five European regional security coordinators (RSCs) are working on what is arguably the most important task for ensuring the security of electricity supply at continental level: a stable and secure transmission system. RSCs analyse critical grid situations from a regional perspective and advise their customers in order to avoid bottlenecks or even blackouts. One of them is TSCNET Services. A detailed background article published by “Energie & Management”, a renowned daily German print and online newspaper for the energy market, portrays the company and presents the special challenges that an RSC has to face every day.

For example, a critical situation occurred in the very cold January 2017. “Even though the redispatch coordination functioned well at that time, the emergence of grid bottlenecks has shown that in the course of the expansion of renewable energies in Europe, we need to identify critical conditions and developments even faster”, explains Maik Neubauer, one of the two managing directors of TSCNET Services. For this reason, TSCNET, in close cooperation with the partner TSOs, has established the “Critical Grid Situation Service” to facilitate communication between the RSC and the TSOs.

Close and seamless communication is crucial for TSCNET Services, because the RSC does not intervene in the transmission network itself, but gives recommendations for action. The final decision, however, lies with the responsible TSO, which can always rely on the validity of the information provided by TSCNET. To ensure this reliability, the specialists at TSCNET monitor the network flows in Central and Eastern Europe. This involves a lot of data: More or less 600,000 data series with a volume in the double-digit gigabyte range yield around 300 prognoses every single day – a “big data company with top advisory expertise”.

Still, the volume of data will continue to increase, especially in view of the implementation of the Common Grid Model (CGM) under the EU network codes. “Today, we still lack some data, especially about the situation at the interfaces to the distribution grids”, states Maik Neubauer. Once the individual grid models of the respective TSOs and the CGM have been established, the additional data also flows into the calculations of TSCNET. This will expand the RSC’s perspective and further optimise system operation. While critical situations affecting only two TSOs can be resolved bilaterally, it becomes more difficult, if several parties are involved. An incident in Poland, for instance, may well affect not only Germany but also the Czech Republic. In such a case, the central coordination provided by TSCNET is essential to anticipate problems or to calculate short-term effects.

Every day at 9:00 pm, TSCNET’s Daily Operational Planning Teleconference (DOPT) with the TSOs’ experts will be held to summarise system occurrences and to coordinate possible compensation measures for the next day. Though everyone involved is quite satisfied with this daily routine, the EU is also pursuing divergent plans. In the context of the European Commission’s “Clean Energy for All Europeans” package, the idea of Regional Operational Centres (ROCs) came into being, which would extend the role of current RSCs by giving them operational responsibility. The TSOs – who would have to hand over competences – are sceptical, and also Maik Neubauer has clear positions in this regard. He points out the complexity of the European power system and the valuable experience of national TSOs. Mr. Neubauer therefore prefers to further improve regional coordination and to leave the operational business to the TSOs: “A Europe-wide centralisation of grid control would be a mammoth project with many risks and unknowns.”

“Energie & Management”, the well-esteemed German trade magazin for the energy market, released an article on the Munich-based RSC TSCNET Services.

CGM methodology framework concluded

03.07.2018

Good news comes from the methodologies drafting team of the Common Grid Model (CGM) Programme under the supervision of the European Network of Transmission System Operators for Electricity (ENTSO-E): Two additional methodologies have been approved by all the relevant national regulatory authorities. This means that the methodological framework for the CGM process has been completed.

In order to create an integrated European energy market, the European Commission has established guidelines on electricity transmission system operation in various Commission Regulations. All European transmission system operators (TSOs) are obliged to prepare and implement a CGM methodology. The joint TSO proposal on the last two CGM methodologies has been openly consulted in late 2017 and then been submitted to the authorities. Formal approvals at the respective national levels are still pending and are expected in September 2018.

The framework now consists of five methodologies (CGMM-v1-plus, CGMM-v2-plus, CGMM-v3, GLDPM-v1, and GLDPM-v2) covering technologically significant aspects such as capacity allocation, congestion management and forward capacity allocation. The GGM methodologies in their entirety ensure that each TSO involved has access to all the necessary data to build its individual grid model.

The framework for the Common Grid Model Methodology with five methodologies is completed.

Proposal for a CGM Methodology

20.03.2018

The European Commission considers an integrated European energy market to be crucial for maintaining supply and operational security as well as for increasing competitiveness. Hence, the Commission has adopted Commission Regulation (EU) 2017/1485 of 2 August 2017 establishing a guideline on electricity transmission system operation, which obliges all European transmission system operators (TSOs) to prepare a Common Grid Model Methodology (CGMM).

Coordinated by the European Network of Transmission System Operators for Electricity (ENTSO-E), all TSOs jointly drafted a proposal for a CGMM. This was openly consulted from 6 November to 6 December 2017 and then revised in the light of stakeholder feedback. Now, the audited CGMM proposal has been approved by all TSOs for submission to the relevant regulatory authorities.

CGMES adopted by the IEC

07.09.2017

The Common Grid Model Exchange Specification (CGMES) has been developed by the European Network of Transmission System Operators for Electricity (ENTSO-E) in close cooperation with its member transmission system operators (TSOs). The CGMES is a key element of the wider Common Grid Model framework for the smartening of the European power system and has proven to be most suitable for regional coordination and pan-European data exchange.

Due to its high efficiency, CGMES has now been adopted by the International Electrotechnical Commission (IEC). This move by the IEC has turned CGMES into an internationally recognised specification for the exchange of electricity data. According to Laurent Schmitt, ENTSO-E’s Secretary General, the adoption clearly manifests the innovative potential of the European power networks. Mr Schmitt expressed his thanks to “all who took part in this great success”, first and foremost mentioning “our member TSOs”.

Public consultation on GLDPM and CGMM

07.03.2017

The European Network of Transmission System Operators for Electricity (ENTSO-E) has opened the public consultation on revised drafts of the Generation and Load Data Provision Methodology (GLDPM) and the Common Grid Model Methodology (CGMM). Revisions had become necessary due to requirements from EU-regulation 2016/1719.

GLDPM is a key element for meeting EU-targets on capacity calculation and for implementing the Common Grid Model. Stakeholders are invited to comment on both methodology drafts via web forms.

The ENTSO-E consultation on GLDPM complements the GLDPM-poll opened by the four German transmission system operators (TSOs) and TSC members 50Hertz, Amprion, TenneT, and TransnetBW earlier this year. Here, concerned parties are given the opportunity to comment on the TSO suggestions concerning the GLDPM implementation in Germany.
