    Closing security loopholes in power grids

    The way in which electricity distribution networks operate is changing considerably as a result of the energy transition. Decentralised systems are increasingly being connected via the Internet with the central control rooms of the energy providers for control purposes. The risks that can arise due to security loopholes in the information system are accordingly growing. In a guide, researchers at Bremen University of Applied Sciences show how the operational management can be secured and how the risks can be limited if measures fail.  more...
     

    Local electricity networks become flexible and resilient

    For three years, the Saarlouis municipal utility company, together with partners from science and industry, has worked on the development of what are known as resilient poly-networks. These autonomous electricity networks at the local level are designed to adapt dynamically to the respective network situation in order to ensure optimum supply. The findings were recently presented at a concluding event.  more...
     

    Modular battery storage system supplies balancing energy

    How can large-scale battery storage systems help stabilise electricity grids and at the same time be profitable? This question is being investigated by scientists at RWTH Aachen University in collaboration with industrial partners using the large-scale M5BAT battery storage system. Using a modular and flexibly scalable batteryinverter concept they are testing the interaction of different accumulator technologies and are developing business models for decentralised storage systems in real grid operation.  more...
     

    “The energy system of today is much more complex than in the past”

    Preparations are currently under way for a new energy research programme, which the German Federal Government intends to publish in the coming legislative period. In preparation, the German Federal Ministry for Economic Affairs and Energy has started a discussion process between representatives from industry, science and politics in order to identify relevant fields of research. In this interview Dr Johannes Tambornino, Head of Energy Strategies and System Analysis at Project Management Jülich speaks about the growing importance of system analysis for energy research.  more...

    Flexible turbomachines stabilise the power grid

    In future, conventional power plants will need to become more flexible in order to compensate for the fluctuating power generation by renewables. This requires modified gas and steam turbines. These will have to work more frequently under partial load, with more start-up and shut-down cycles and function with changing fuels. AG Turbo has compiled the research and development objectives for these new framework conditions in the ECOFLEX-turbo programme.  more...

    40 years of energy research

    Last week, on 2nd May 2017, the German Federal Minister for Economic Affairs, Brigitte Zypries, opened the celebration for the anniversary of “40 years of energy research programmes in the German Federal Government” in the historic conference rooms of the German Federal Ministry for Economic Affairs and Energy in Berlin. She emphasised that research and development are important components in the large modernisation and investment project for energy transformation in Germany.

    Superconductors for the medium-voltage grid

    Scientists are testing the longest high-temperature superconducting cable in the world under real conditions in Essen. One kilometre long, it connects two substations in the inner city. It replaces a conventional 110 kV line and renders one substation in the inner city obsolete. After two years of testing, it has passed the field test. It could be a blueprint for the future power supply system in urban areas.  more...

    Networked factory stabilises the grid

    The factory of the future is flexible and networks the energy flows between machinery and buildings. The so-called Phi Factory is not only very energy-efficient, it also helps stabilise the electrical supply grid. The new model factory relies on a high share of renewable energy and helps smooth out electricity supply fluctuations.  more...

    Storing surplus electricity in the natural gas network

    Surplus electricity can be used in Power-to-Gas systems to generate hydrogen by means of electrolysis. Downstream methanation provides a possibility for storing the remaining gas that cannot be directly used or fed into the natural gas network. The initial, highly promising results for a newly developed biological process have now been presented. The test facility has a low energy requirement and the process is continuous. The system is suitable for decentralised and small systems.  more...
     

    The hotline in the grid

    The electricity grid that has been used for decades reaches its limits when transporting increasing amounts of electricity over long distances. There are already limiting bottlenecks. One way to integrate more wind and solar power into the grid is provided by overhead lines with a higher maximum temperature. These can transport more electricity, enabling grid congestion to be avoided. One problem, though, is that metals expand more at high temperatures. As a result the line lengthens and sags more. However, special high-temperature conductors can provide a remedy here.  more...
