ELES and Renault cooperate in e-mobility project

09.08.2019

“Demonstration of User-Friendly E-Vehicle Charging Solutions for Promoting Mass Use of E-Vehicles in Europe – INCIT-EV” is the somewhat lengthy but therefore very precise and apposite name of a research project conceived by TSCNET shareholder ELES together with 32 international partners. Probably the most prominent cooperation partner of the Slovenian transmission system operator (TSO) is the French multinational automobile manufacturer Renault, but the Italian automotive industry is also actively involved.

The core objective of the project, funded by the EU with around €15m under the framework of the Horizon 2020 programme, is the utilisation of advanced charging infrastructures and technologies and the development of corresponding business models. INCIT-EV is designed in line with the concept of the “E8 E-Vehicle Mass Charging Infrastructure” developed by ELES, which strives to make charging as simple, intuitive, and user-friendly as possible. The aim of the TSO is to extend the Slovenian E8 concept to the European level. The project partners also use neuroscientific techniques to adapt the development of the technology to the unconscious preferences and subjective expectations of e-car users.

50Hertz and TenneT awarded for PtG projects

26.07.2019

Last week, Peter Altmaier, the German Federal Minister for Economic Affairs and Energy, announced the winners of the ideas competition “Reallabore der Energiewende” (“Real Laboratories of the Energy Transition), which aims to promote promising energy technologies of the future, especially in the field of hydrogen technology. The winners include the two TSCNET shareholders 50Hertz, the transmission system operator (TSO) from north-east Germany, and Tennet, the Dutch-German TSO, as they are both involved in award winning projects.

Tennet is cooperating with Gasunie and Thyssengas for ELEMENT ONE, a power-to-gas (PtG) plant to be built in the German federal state of Lower Saxony, which will be capable of converting up to 100MW of electrical power into gas. ELEMENT ONE is in the planning phase, but the project partners are confident that the results of the project will provide crucial information on electricity and gas grid integration, the development of operator models and the regulatory environment. With their approach, they aim to accelerate the urgently needed transfer of technology and innovation from research to practice in the field of sector coupling and hydrogen technology.

Key technologies of energy supply
50Hertz is involved as associated partner in two winning PtG projects: “GreenHydroChem Mitteldeutsches Chemiedreieck“ in Saxony-Anhalt, and “Reflau – Referenzkraftwerk Lausitz“ in Brandenburg. These two projects also focus on sector coupling and hydrogen technology. The partners for GreenHydroChem are Siemens, Linde, and the Fraunhofer Institute for Microstructure of Materials and Systems (IMWS). With a 50MW electrolyser, regeneratively generated electricity is first to be converted into hydrogen and oxygen. The hydrogen is then converted in refineries into base chemicals and methanol, which can be blended with conventional fuels for the use in the transport sector. With Reflau, the partners want to combine and test in practice key technologies of energy supply with renewable energies and hydrogen as a chemical storage.

Dr. Dirk Biermann, Chief Markets & System Operations Officer at 50Hertz, welcomes the support for innovative technologies: “With our involvement in the laboratories, we are specifically promoting the development of Power-to-X technologies for the energy market. Because if things get serious in a few years’ time, we will need proven and grid-compatible experience with this new technology.”

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.

New FCR market design

04.07.2019

The collaboration of central European transmission system operators (TSOs) in the procurement and exchange of Frequency Containment Reserve (FCR) is the first regional cooperation in Europe to implement market harmonisation in compliance with the EU Guideline on Electricity Balancing (EBGL). The TSOs that make up the FCR consortium are: the Austrian, German and Swiss TSCNET shareholders APG, 50Hertz, Amprion, TransnetBW, and Swissgrid, the Dutch-German shareholder TenneT as well as the Belgian TSO Elia and the French TSO RTE, which are supplemented by further TSCNET shareholder Energinet from Denmark as non-active member.

The FCR cooperation was founded in the summer of 2016 and has conducted two consultation rounds in the last two years, resulting in a final proposal, which was approved by all national regulators involved. The first milestone in the advancement of the largest FCR market in Europe has now been reached in the implementation of a new FCR market design. In addition to shortening the product length from a week to a day, the cooperation introduces a marginal pricing system. The aim is to reduce procurement costs and create incentives for new balancing power providers and technologies to enter the market.

Connect+ for data exchange

14.06.2019

The four German transmission system operators (TSOs), the TSCNET shareholders 50Hertz, Amprion, TenneT, and TransnetBW, together with 16 distribution system operators (DSOs) have launched the “Connect+” project to jointly implement the legal requirements of the German Grid Expansion Acceleration Act (Netzausbaubeschleunigungsgesetz – NABEG). The project is a reaction to the increased need for coordination due to the current legislative amendments and intended to facilitate a more transparent exchange of data between grid operators and market participants.

German legislation has specified that, in future, all facilities for the generation or storage of electrical energy with a nominal capacity of 100kW or more must be utilised to prevent foreseeable bottlenecks in the grid. The modified conditions for redispatch apply from 1 October 2021. As the present feed-in management of the grid operators only reacts to acute congestions, an even more intensive cooperation between TSOs and DSOs is required in the future.

The new processes to be developed and introduced within the time frame pose a challenge for all grid operators. In the “Connect+” project, TSOs and DSOs want to develop uniform solutions for data distribution to harmonise data exchange between market participants and operators for congestion management. In a first step, essential specifications such as interfaces and formats are developed and defined.

AI for decentralised grid stabilisation

06.06.2019

In a sustainable energy future, small decentralised plants such as combined heat and power (CHP) plants, heat pumps or biogas units must assume the role of stabilising the transmission system, a task which is nowadays mainly performed by large, centralised power plants. To investigate the technical feasibility of decentralised stabilisation options, TSCNET shareholder TenneT, the Dutch-German transmission system operator (TSO), the distribution system operator (DSO) Bayernwerk and Consolinno Energy GmbH have now jointly carried out a successful test in the southern part of the TenneT control area, the German federal state of Bavaria.

Since there is a vital public interest in such future-oriented technological solutions, the test was funded by the German Federal Ministry for Economic Affairs and Energy in the framework of the research project “C/Sells” which is part of the innovation programme “Smart Energy Showcases. Digital Agenda for the Energy Transition” (“Schaufenster intelligente Energie. Digitale Agenda für die Energiewende” – SINTEG). During the test, at the request of TenneT, the feed-in of a CHP plant controlled by Consolinno and connected to the low and medium-voltage grid of Bayernwerk was increased in order to provide the grid with the electricity required for stabilisation in the event of a bottleneck.

What is new is that each plant autonomously determines its flexibility potential through artificial intelligence (AI). The respective potential of the individual plants can then be further aggregated by means of swarm intelligence. The plants are in normal marketing and operation mode and report free flexibility quantities to the grid operators. “In Bavaria alone there are several thousand CHP plants, heat pumps and biogas facilities, nationwide there are many thousands more. They can increase the flexibility of the energy system and thus contribute to a safe and decentralised energy system in Bavaria and Germany. David can thus become Goliath,” comments Tim Meyerjürgens, COO at TenneT. Also in several other cooperative pilot projects, the TSO is exploring the potential of decentralised flexibility.

ČEPS and SEPS to participate in IPDE

05.06.2019

The International Phasor Data Exchange (IPDE) platform is a multinational project to facilitate and optimise the exchange of operational data within the European interconnected transmission system. More specifically, these data derive from time-synchronous voltage, current phasor and frequency measurements which are collected and used in Wide Area Monitoring Systems (WAMS). IPDE is now making significant progress as the two TSCNET shareholder ČEPS and SEPS, the Czech and Slovak transmission system operators (TSO) respectively, have signed an agreement on participating in the platform.

Martin Durčák, Chair of the Board of Directors of ČEPS, comments that the “participation in the platform is another of our continual steps in the introduction of technological innovations and shift towards a digitally managed and controlled grid”. Miroslav Obert, CEO of SEPS, complements: “The project we are undertaking in collaboration with our Czech partners ensures method simplification and uniformity of phasor data exchanges between individual TSOs.”

High potential of blockchained home storage systems

09.05.2019

Maintaining the balance of the transmission system despite volatility of renewables and lack of conventional operating reserves is an essential future concern of European transmission system operators (TSOs). In search of adequate balancing solutions, a worldwide unique pilot project for the blockchain-based networking of home storage systems was launched in 2017. The cooperation partners are TSCNET shareholder TenneT, the Dutch-German TSO, and sonnen, a company specialised in smart power storage. The promisingly completed pilot demonstrates the potential of blockchain technology to become a key application for the efficient provision of network stabilising measures.

The aim of the pilot was to test the suitability of blockchained storage systems for preventing emergency measures in the event of bottlenecks, e. g. the throttling of wind farms. To this end, TenneT deployed a virtual power station comprising of home storage systems specially provided by sonnen with a blockchain solution by IBM. The intelligent charge management of the battery storage systems adapted itself individually to the respective situation in the TenneT grid, whereby the batteries absorb or release excess current within seconds if required.

Manon van Beek, CEO of TenneT, comments on the succesful project: “We’ve shown for the first time how it’s technically feasible to utilise blockchain technology so households can stabilise the power grid via their home storage systems.” Actually, the results are so promising that TenneT intends to undertake further blockchain programmes, especially as by 2030 there could already be decentralised battery storage facilities in Germany with a total capacity of up to 10,000MW.

A pilot project by TenneT on blockchained home storage systems for grid stabilisation has proven the high potential of this technological approach (picture: edited screenshot taken from sonnen video “The largest virtual battery to compensate for fluctuations in the power grid”, YouTube)

NEDO Project meetings in Tokyo

24.04.2019

A three-year Slovenian-Japanese smart grid project was launched in November 2016. The main partners are the Japanese New Energy and Industrial Technology Development Organisation (NEDO), its authorised contractor Hitachi, the multinational conglomerate, and TSCNET shareholder ELES, the Slovenian transmission system operator (TSO). In addition to ELES, numerous Slovenian stakeholders also contribute to the NEDO Project, the aim of which is to implement a smart grid at national level. For the power system, the benefits lie in innovative solutions that reduce the need for grid extension, as the use of advanced secondary equipment, information, communication and cloud technologies allows better utilisation of the existing grid.

Last week, two NEDO Project meetings took place in the Japanese capital Tokyo. On 17 April, Gorazd Ažman, Assistant Director of the Strategic Innovation Department at ELES, and a representative of Hitachi informed the members of the NEDO Project Steering Committee and the Advisory Board about the current project activities in the Hitachi premises. The next day, a second meeting followed, this time at the NEDO headquarters with high representatives of the Japanese Ministry of Infrastructure, the Ministry of Economic Development and Technology, ELES, NEDO and Hitachi.

BioEnergyTrain reaches its final station

11.04.2019

Concerning its engagement in projects with pan-European value, the Slovenian TSCNET shareholder ELES plays a very committed role as a national transmission system operator (TSO) with international ambitions. Among the European projects in which ELES is involved are FutureFlow for innovative e-trading solutions, MIGRATE for linking generation and consumption via power electronics, DEFENDER for the protection of critical energy infrastructures or the smart grid project SINCRO.GRID.

The first project participation of ELES under the EU Horizon 2020 programme is the BioEnergyTrain (BET). The members of the BET consortium – fifteen partners from six EU countries – recognise the high importance of bioenergy for the low-carbon future and therefore want to tackle the lack of qualified personnel, of coordination between stakeholders and the poor coherence between professional training and industrial needs. They address these issues by creating new postgraduate curricula in key bioenergy disciplines and a network of educational and research institutions, professional associations and industry stakeholders from the entire bioenergy value chain.

In BET, ELES took on the role of head of regional awareness raising, thus successfully finishing the first Horizon 2020 project proposal as the whole project has now been completed after four years of developing innovative educational materials. The main outcome are two new Master programmes at the Graz University of Technology in Austria and at the University of Twente in the Netherlands. The final BET conference took place in Brussels, Belgium on 9 April.
