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.

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.

PtG pilot plants on an industrial scale

29.03.2019

Power-to-Gas (PtG) technologies have the potential to compensate for the weather-related volatility of renewable energies. More specifically, PtG can be used to convert sustainable electricity into gas (green hydrogen or methane), so that the gas infrastructure is additionally available for the transport and storage of electricity from renewable sources. The TSCNET shareholder Amprion, one the four German transmission system operators (TSOs), and TenneT, the Dutch-German TSO, are taking the next important step towards implementing the two most powerful sector coupling projects currently underway in Germany: “hybridge” and “ELEMENT ONE”.

The respective gas transmission partners of Amprion and TenneT are Open Grid Europe for the “hybridge” project and Gasunie and Thyssengas for ELEMENT ONE. Both PTG plants are to convert up to 100MW of electrical power into gas. Their construction is planned at two different sites in the German federal state of Lower Saxony, each close to wind power generation centres and well-developed gas infrastructure.

The grid operators have submitted the necessary investment applications for both projects on 29 March to the Bundesnetzagentur (German Federal Network Agency). If the Agency gives the green light, ELEMENT ONE will be gradually operational by 2022 and hybridge will be fully functional by 2023. Dr. Klaus Kleinekorte, CTO at Amprion, comments on the application, that major PtG projects must now be pushed forward, “if we want to use PtG technology on a large scale in Germany in the 2030s”.

First capacity offers on WindNODE platform

17.03.2019

Today’s energy market, with its ever-increasing share of volatile quantities of electricity from renewable sources, demands optimum capacity utilisation and systematic use of flexibility – already now and even more so in the future. To be well prepared for the challenges ahead, more than 70 partners from all over eastern Germany are working on the WindNODE project, including TSCNET shareholder 50Hertz, the German transmission system operator (TSO) responsible for the region. A core component of WindNODE is the flexibility platform, through which regional producers, consumers, and storage operators offer TSOs and distribution system operators (DSOs) flexible use of their facilities. This is intended to reduce the throttling of wind turbines in the event of grid bottlenecks.

The WindNODE flexibility platform has been in trial operation since November 2018. On 14 March 2019, capacities were offered and called up for the first time. “This means that the trial operation is now entering the practical phase and we can demonstrate that the integration of numerous producers, storage facilities and consumers in one market environment leads to less throttling of renewables – especially now in a very windy season,” explains Georg Meyer-Braune, project manager WindNODE at 50Hertz. The test phase of the platform will last until summer 2019 and processes will be gradually established at further partners, who will thus become potential suppliers. The platform will then be in continuous operation until the end of the project term in 2020. The aim is to use the dedicated facilities for congestion management also after the completion of the WindNODE project.

Hybridge to couple energy sectors

11.02.2019

Last summer, TSCNET shareholder Amprion, one the four German transmission system operators (TSOs) for electricity, and Open Grid Europe (OGE), German TSO for natural gas, announced a collaboration in the field of sector coupling by means of power to gas (PtG) facilities. PtG technologies offer promising perspectives for a low-carbon energy future. Now the two partners are ready to launch the sector coupling at system level in Germany with the project “hybridge” comprising an electrolyser in the 100MW class and a hydrogen infrastructure.

At a joint press conference on 11 February in the German capital of Berlin, the current status of hybridge and further steps were presented. Since the partners, who estimate the costs for the entire project at €150m, are ready to enter the approval phase, Dr. Klaus Kleinekorte, CTO at Amprion, explained that the regulatory framework must now be set up quickly. The more so, as it is crucial for the German climate targets that PtG is available in the GW range from 2030. “The ball is in the court of politics. If the course is set now, the plant can already go into operation in 2023,” commented Dr. Kleinekorte.

The ideal location for the first PtG plant in the projected size, in which electricity from renewable energies is converted into green hydrogen and partly further into green methane via an electrolyser, was found at an intersection between the Amprion and OGE grids in the district of Emsland in the northwest of the German federal state of Lower Saxony. The regional natural gas storage facilities, which can be converted to hydrogen in the future, also contribute to optimal conditions for the development of a hydrogen grid to complement the 100MW electrolyser. Amprion and OGE intend to further develop an existing OGE pipeline for the exclusive transport of hydrogen. The concept of Amprion and OGE for sector coupling at system level also includes non-discriminatory third-party access for all market participants to the planned grid coupling infrastructure.
