Awards for ELES smart grid projects

30.07.2020

The International Smart Grids Action Network (ISGAN) is a technology cooperation programme on smart grids by the International Energy Agency (IEA). ISGAN provides a strategic platform to raise awareness and to stimulate action by high level governments for accelerated development and deployment of smart and clean electricity grids around the world. ISGAN initiatives include the annual ISGAN Award of Excellence in “Digitalization Enabling Consumer Empowerment”. On 28 July, the jury announced the winners of the 6th ISGAN Award, which focuses on digitisation at global level and for which nominations have been received from around the world. The first and second prizes were awarded to two projects in which TSCNET shareholder ELES, the Slovenian transmission system operator (TSO), is significantly involved.

The first place goes to the NEDO project, a Japanese-Slovenian initiative whose main partners, besides ELES, are the Japanese New Energy and Industrial Technology Development Organisation (NEDO) and the multinational conglomerate Hitachi. The NEDO project introduces integrated and centrally managed cloud-based solutions to make better use of the existing network and provide customers with a higher quality electricity supply and the opportunity to actively participate in electricity markets and systemic services. ELES decided at the end of 2015 to participate in the project, whose main responsible partner, the namesake agency NEDO, received the award on behalf of the consortium.

The award for FutureFlow, which took second place, was received by ELES itself. The international project was conceived by ELES experts and involves twelve partners from eight European countries. The project implements innovative e-trading solutions for smart cross-border balancing and redispatching in the control areas of four central and southern European TSOs, which are all shareholders of TSCNET. Besides the project leader ELES, the other TSO participants are APG from Austria, MAVIR from Hungary, and Transelectrica from Romania. FutureFlow was launched in 2016 and successfully concluded in December 2019. Pilot tests in real time have proven that also small businesses and power generation units can be a reliable source of flexibility to maintain the balance in the electricity system. The project was funded by the EU under the Horizon 2020 programme, in fact, it was the largest research project financed under Horizon 2020.

The ISGAN Award 2020 is exceptional in that it is the first time that one company receives two awards. After the announcement, the CEO of ELES, Aleksander Mervar, commented that with these two awards, ELES has obtained great international recognition for its activities in the field of innovation and development of smart networks. Mr Mervar complimented the partners in both consortia. By dedicating the two awards to all those who participated in both projects, he acknowledged their outstanding performance.

New Local Implementation Project under SIDC

09.07.2020

European transmission system operators (TSOs) are committed to the European Energy Union by collectively working towards an integrated European electricity market. A key component for market integration is cross-border Single Intraday Coupling (SIDC), which was introduced as XBID in June 2018. SIDC is designed to increase the overall efficiency of intraday trading through effective competition, increased liquidity, and more efficient use of generation resources. Currently, the markets of 22 countries are coupled through SIDC: Austria, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Hungary, Latvia, Lithuania, Luxembourg, Netherlands, Norway, Poland, Portugal, Romania, Slovenia, Spain, and Sweden. With the inclusion of the Slovakian Nominated Electricity Market Operator (NEMO) OKTE and TSCNET shareholder SEPS, the TSO from Bratislava, the project also extends to Slovakia.

Within the framework structure of the SIDC, Local Implementation Projects (LIPs) provide for the expansion of the market coupling, and a new project has now been established as LIP 17. The NEMOs and TSOs from the Czech Republic, Hungary, Poland, and Slovakia – the TSCNET shareholders ČEPS, MAVIR, PSE, and SEPS – have proposed to implement SIDC across the borders between Slovakia-Czechia, Slovakia-Hungary, and Slovakia-Poland. The SIDC Steering Committee approved on 7 July and the LIP 17 roadmap will now be elaborated in more detail.

The SIDC solution comprises a common IT system with a shared order book, a capacity management module, and a shipping module. In addition to the TSOs mentioned above, the TSCNET shareholders 50Hertz, Amprion, APG, ELES, HOPS, TenneT, Transelectrica, and TransnetBW as well as the TSCNET customers Creos from Luxembourg and Energinet from Denmark are also part of SIDC.

SVC for SINCRO.GRID in Konjsko

02.07.2020

As in many parts of Europe, the increasing integration of decentralised, volatile renewable energy sources has also led in Croatia and Slovenia to a lack of flexibility and reactive power. The two TSCNET shareholders HOPS, the transmission system operator (TSO) from Croatia, and ELES, the Slovenian TSO, react to this with their joint project SINCRO.GRID that also involves two distribution system operators (DSOs) from the respective countries. The European Project of Common Interest (PCI) aims to optimise the efficiency of the two national electricity transmission networks through advanced technologies and innovative data processing methods. These include compensation devices, a dynamic thermal rating system, a battery power storage system, and a virtual cross-border control centre.

The start of construction of a static VAR compensator (SVC) in the Dalmatian substation in Konjsko on 30 June represents another significant milestone in the implementation of SINCRO.GRID. This state-of-the-art compensation system will support HOPS in actively controlling the reactive power flows in the Croatian power grid. The ceremony to mark the construction start was attended by high-ranking representatives of the Croatian government and the energy companies involved.

In addition to the SVC in Konjsko, SINCRO.GRID comprises three further main elements in Croatia: a variable shunt reactor (VSR) in the Mraclin substation near Zagreb, which was commissioned in January 2020, another VSR in the Melina substation, which is scheduled to be commissioned at the end of 2020, and finally a joint Croatian-Slovenian virtual control centre. Tomislav Plavšić, President of the HOPS Management Board, describes the latter as a unique solution for coordinated voltage regulation on the entire territory of both countries. The principal task of the binational virtual centre is to integrate three devices each in Croatia and Slovenia for reactive power compensation into one common operation to fully exploit their synergy potential.

Successful start of FCR auctions

01.07.2020

The cooperation on regional procurement and exchange of frequency containment reserve (FCR) is a voluntary initiative of eight transmission system operators (TSOs): the six TSCNET shareholders 50Hertz, Amprion, and TransnetBW from Germany, APG from Austria, Swissgrid from Switzerland, and the Dutch-German TSO TenneT, as well as Elia from Belgium and the French TSO RTE. The FCR project is the first regional cooperation for a common market based on the methodology for the exchange of control reserves set out in the EU Guideline on Electricity Balancing. Within the scope of a cooperation model with Amprion, the Luxembourg TSCNET customer Creos is also involved.

The next milestone in the development of the largest European market for primary balancing power reserve has now been reached, as the first D-1 auction for FCR with 4-hour products was successfully conducted on 30 June 2020. This means, the FCR cooperation reduces the product length from one day to four hours and thus the market for primary balancing power is brought closer to real time.

Due to stronger competition between service providers and technologies, the joint auction allows TSOs to procure FCRs at minimum cost to end-users while offering a large common market for all providers of balancing services. It also increases the market attractiveness for short-term flexibility, limits price volatility and improves the security of grid operation by executing cross zonal procurement of FCR. The FCR market, already the largest in Europe, will be extended to western Denmark and Slovenia in the first quarter of 2021, so that with Energinet and ELES two further TSCNET shareholders will broaden the project.

Virtual InnoGrid focuses on Green Deal

19.06.2020

Grid innovators usually meet once a year in Brussels to participate in InnoGrid2020+, the European event for research, development, and innovation (RDI) in the field of power transmission. Despite the continued commitment of the European transmission system operators (TSOs) to RDI and the energy transition during the Covid-19 pandemic, this year’s Innogrid2020+ must be conducted virtually. The European Network of Transmission System Operators for Electricity (ENTSO-E) and the European Distribution System Operators’ association (EDSO) have thus organised two InnoGrid webinars to showcase the latest innovations and to present some of the key research and development projects in Europe. The first webinar, attended by 350 people, took place on 18 June, and the second will follow on 30 June (11-13 CET).

The motto of the online events is: “Why power networks innovation is key for bringing the European Green Deal from promise to practice”. The first webinar provided ideas and projects that help to make the Green Deal a reality, especially by facilitating the integration of renewable energies. In addition to technical approaches and projects, political and regulatory framework conditions were also discussed. In his assessment of the development from an ENTSO-E perspective, Uroš Salobir, Director of the Strategic Innovation Department at TSCNET shareholder ELES, the Slovenian TSO, and ENTSO-E Vice Chair of the RDI Committee, commented: “The future energy system will be a system of interconnected systems, with deeper electrification and smart sector integration. In this future, electricity becomes a dominant vector and system operators, key facilitators.” On behalf of European TSOs, Mr Salobir concluded: “We stand ready to support the European green recovery especially through innovation and developing the cyber-physical system.”

Reservations for the second session on 30 June are still welcome. Among other topics, Michela Marasco, Policy Officer-DG Energy at the European Commission, will speak on the RDI dimension of the Green Deal. Jan Kostevc, Infrastructure Regulation Officer at the Agency for the Cooperation of Energy Regulators (ACER), will focus on innovations from the efficiency perspective and Hakon Borgen, Chair of the ENTSO-E RDI Committee, will present the ENTSO-E RDI Roadmap 2020-2030.

This year’s InnoGrid2020+ on the relevance of grid innovation for the European Green Deal is held as a webinar

SIDC: Massive growth in trading volume

02.04.2020

European cross-border Single Intraday Coupling (SIDC) was introduced in June 2018 (then called XBID) to increase the overall efficiency of intraday trading through effective competition, increased liquidity, and more efficient use of generation resources. The overarching objective is the integration of the European energy market. In November 2019, SIDC was extended in a second go-live, so that currently the markets of 22 countries are coupled through SIDC: Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Latvia, Lithuania, Luxembourg, Norway, the Netherlands, Portugal, Spain, Sweden (first go-live), and Bulgaria, Croatia, the Czech Republic, Hungary, Poland, Romania, and Slovenia (second go-live).

The Nominated Electricity Market Operators (NEMOs) from the seven countries of the second go-live report significant growth in trading volume in the coupled intraday market. The Hungarian NEMO HUPX, for example, recorded an average monthly trading volume of around 75,600MWh from December 2019 to February 2020 compared to 7,600MWh in the same period of the preceding year; in the Czech Republic, the volume has increased eightfold. The other NEMOs are also registering significant growth rates. A total of 36 million trades have been executed since SIDC first went live, and the system continues to operate reliably after the second wave.

The SIDC solution is based on a common IT system with a shared order book, a capacity management module and a shipping module. The TSOs cooperating in SIDC include the TSCNET shareholders 50Hertz, Amprion, APG, ČEPS, ELES, HOPS, MAVIR, PSE, TenneT, Transelectrica and TransnetBW, as well as the TSCNET customer Creos from Luxembourg and Energinet from Denmark. With the accession of the NEMO OKTE and further TSCNET shareholder SEPS, the TSO from Bratislava, the project has meanwhile been extended to Slovakia. A third go-live to expand continuous cross-border intraday trading to Greece and Italy is expected in the first quarter of 2021.

HOPS commissions variable shunt reactor

22.01.2020

A further step for the successful implementation of the Croatian-Slovenian smartgrid project SINCRO.GRID has been taken. The European Project of Common Interest (PCI) aims at optimising the efficiency of the Croatian and Slovenian electricity transmission grids through the application of advanced technologies and innovative data processing methods and is carried out by the two TSCNET shareholders ELES, the Slovenian transmission system operator (TSO), and HOPS from Croatia.

At the beginning of December 2019, the ELES substation in Divača has been equipped with a variable shunt reactor, an effective compensation tool for reactive power control. Now HOPS has put the same technically advanced system into operation at its substation in Mraclin near Zagreb. With this, HOPS has concluded the first stage of SINCRO.GRID. After the implementation of additional measures and devices, including a static VAR compensator, the Croatian TSO will be able to actively manage the reactive power flows in the Croatian power grid. This will solve problems of overloads in the long term and thus have a positive effect on grid stability and security of supply for customers.

Final MIGRATE conference

10.12.2019

The MIGRATE project (“Massive InteGRATion of power Electronic devices”) is the largest TSO project funded by the European Commission. It was launched in 2016 in the framework of the Horizon 2020 programme. Among the 23 partners of the consortium from 13 European countries are twelve universities/labs, one manufacturer and ten transmission system operators (TSOs), including the TSCNET shareholders Amprion (Germany), ELES (Slovenia) and the Dutch-German TSO TenneT. Under the coordination of TenneT, the partners have researched technology-based solutions for an optimised linking of electricity generation and consumption by means of power electronics.

After four years of intensive work, the MIGRATE project will be successfully concluded by the end of 2019, implying that all project partners have developed innovative solutions in their respective areas of responsibility to gradually adapt the pan-European high-voltage AC transmission system to the requirements resulting from the increasing share of renewable energies and power electronic devices. At a final conference on 4 December in Brussels, the individual outcomes were presented to colleagues and anyone wishing to learn more about the power system stabilisation and grid monitoring capabilities. The keynote speech was given by Laurent Schmitt, Secretary General of the European Network of Transmission System Operators for Electricity (ENTSO-E).

Variable shunt reactor for SINCRO.GRID

03.12.2019

The two transmission system operators (TSOs) and TSCNET shareholders ELES from Slovenia and HOPS from Croatia are cooperating in SINCRO.GRID. This cross-border smart grid initiative is coordinated by ELES and comprises in addition to the TSOs also two distribution system operators (DSOs) from both countries. The objective of the European Project of Common Interest (PCI) is to optimise the efficiency of the respective national transmission systems by means of advanced technologies and innovative data processing methods.

Since the substantial allocation of EU funding to SINCRO.GRID under the Connecting Europe Facility (CEF) programme in 2017, the project has made significant progress. A vital component of SINCRO.GRID is optimising and installing compensation devices for reactive power control, e.g. variable shunt reactors, which are used in high-voltage transmission systems for voltage stabilisation during load variations. Now the ELES substation in Divača in south-eastern Slovenia has been equipped with such a technically advanced device manufactured by Siemens in Austria. The assembly work is in full swing and is expected to be completed by 12 December. Preparatory work for commissioning will then commence immediately.

Another major component of SINCRO.GRID is a dynamic thermal rating system for power grid operating limits. The aim is to evaluate marginal capacities of transmission system components considering weather influences and thus to improve operational safety and utilisation of overhead lines and transformers. In addition to hard- and software in control centres, atmospheric measuring devices, which are installed directly at the pylons, are also part of the system. Corresponding tests of innovative weather stations are underway. Last week, the substructure for the weather station on the Kleče-Divača overhead line was field tested.

Single Intraday Coupling expanded

08.11.2019

Europe-wide intraday coupling is a key component for the completion of the European internal energy market. To help achieve this goal, the European cross-border Single Intraday Coupling (SIDC) solution was launched in June 2018 (then called XBID), standing for a significant step towards a single integrated continent-wide intraday market. A market of this kind increases the overall efficiency of intraday trading through effective competition, increased liquidity and more efficient use of generation resources across Europe. The SIDC solution is based on a common IT system with a common order book, a capacity management module and a shipping module.

The participating countries were initially Austria, Belgium, Denmark, Estonia, Finland, France, Germany, Latvia, Lithuania, Norway, the Netherlands, Portugal, Spain and Sweden. SDIC will now be expanded and continuous electricity trading will be possible across seven further countries: Bulgaria, Croatia, the Czech Republic, Hungary, Poland, Romania and Slovenia. Nominated electricity market operators (NEMOs) and the participating transmission system operators (TSOs) have confirmed the go-live of the extended SIDC and two additional local implementation projects on 19 November with first deliveries on 20 November.

TSOs already collaborating in SIDC include the TSCNET shareholders 50Hertz, Amprion, APG, TenneT, TransnetBW and Energinet as well as the TSCNET client Creos from Luxembourg. With the second wave, six more shareholders follow, namely ČEPS, ELES, HOPS, MAVIR, PSE and Transelectrica.
