    Compact grid nodes for low-loss electricity transmission

    The development of compact switching points for DC transmission solves a problem caused by the grid expansion: the grid nodes and feed-in systems are becoming smaller and can thus be installed more conveniently in urban areas and on platforms for offshore wind farms. Siemens’ development manager Denis Imamovic is today presenting the latest results of the research project at the Berliner Energietage conference.  more...

    Superconductor begins test operation

    Developers from science and industry are jointly investigating the technical, economic and ecological aspects concerned with superconductor technology in electricity grids. As part of the AmpaCity project in Essen, a two-year test operation is scheduled to be launched this spring with a one-kilometre superconductor test route. This test is designed to show that superconductor technology could provide a future alternative to conventional high voltage technology in cities.  more...

    Efficiently capturing carbon dioxide with spray scrubbers

    Spray scrubbers have been successfully used in power plants for years for desulphurising flue gas. Now it is intended that they should scrub another material – namely climate-harming carbon dioxide (CO2). Until now a hurdle preventing large-scale CO2 capturing has been the high investment costs for the plant technology and the considerable amount of energy required for the operation. The University of Stuttgart is therefore working with partners to improve this process.  more...
     

    Precisely measuring how wind turbines affect the grid

    Every wind turbine that is connected to the grid affects the grid quality. Until now, operators have not known the precise extent to which they do this and instead rely on estimations. In order to make better use of capacities and prevent disruptions, scientists at Helmut Schmidt University in Hamburg have therefore designed a measuring device that determines the effect of wind turbines on the medium-voltage grid. It is planned to produce a measuring device for high-voltage lines by 2016.  more...

    Objective planning of the grid expansion

    The ideal course of a power route depends on a number of factors. Scientists at the Technical University of Dortmund have joined forces with the grid operator Amprion to model a weighting function which systematically reproduces the relevant criteria. A computer-aided planning tool shall enable planners to make an objective assessment of various route layouts, visualise different alternatives and swiftly develop suitable compromises.  more...
     

    German Federal Environment Agency moves into zero-energy building

    The staff at the Federal Environment Agency’s research facilities in the Berlin district of Marienfelde can now test the German government’s first zero-energy building during their daily work. The energy supply is based on the exclusive use of renewable energies: a photovoltaic system produces electricity and a heat pump generates the necessary heating and cooling energy. The building is intended to generate just as much energy as it requires within one year.  more...

    An island becomes power-independent

    The North Frisian island of Pellworm has been a showcase for energy research since the early 1980s. The largest solar farm in Europe was installed there in 1983. In 1989, wind turbines were added to create Europe’s largest hybrid power plant. Now, the island is due to become power-independent, with an intelligent electricity grid with large-scale storage facilities and a large number of home storage systems.  more...
     

    Power plants become partners of renewables

    The “Partner-Dampfkraftwerk” research project, which has now begun, aims to significantly improve the demand-driven integration of electricity from fluctuating energy sources. For this purpose, their goal is that existing power plants will reliably balance out the fluctuating power from wind turbines or photovoltaic systems, in order to ensure grid stability. The optimisation measures could already be installed in the short term in existing power plants. With this aim in mind, four power plant operators are collaborating with three research institutes and two components manufacturers, under the project management of VGB PowerTech.  more...

    Electricity grids without electrical resistance

    The construction of an inner-city pilot route for superconductive cable has begun. The superconductive cable has hardly any electrical resistance. As a 10,000-volt cable, it can therefore transport just as much electricity as a 110,000-volt high-voltage cable. That saves space and simplifies the distribution networks. If the pilot project is successful, this can transform the electricity grids in urban areas.  more...
     

    Storing electricity in the cloud

    How can storage systems be optimally operated? How can the incorporation of renewable energies in the supply grid be supported? These questions are being examined in the "green2store" project. The aim is to unite decentralised storage systems in a virtual cloud and make them accessible.  more...
