    AmpaCity receives innovation award

    Since the spring of 2014, a superconducting cable helps to ensure that the lights stay on in the centre of Essen. It transmits up to 40 megawatts of electricity – almost without loss. With AmpaCity, researchers from science and the electricity industry are demonstrating how high voltage lines and transformer substations could be eliminated in urban areas. On 20 January 2016, the project, which is funded by the German Federal Ministry for Economic Affairs and Energy, was conferred the German Innovation Prize for Climate and the Environment.  more...

    Electricity grid with strong genes

    The electricity grid is both dynamic and sluggish at the same time. On the one hand, it distributes electricity with rapidly fluctuating loads. On the other hand it takes a long time before constructional changes can be planned and carried out, which is due to both technical and social reasons. This makes it important to assess future scenarios with simulations. Scientists at RWTH Aachen are achieving this with their GENESYS software program.  more...

    Securely controlling dynamic electricity grids

    The construction of power plants that generate electricity from the wind and sun continues apace. In particular at high sea, but also in rural areas, there is still considerable development potential during the next few years amounting to several gigawatts. The load centres, however, are situated in the metropolitan areas in the middle and south of the country. It is therefore important to integrate the locally created surplus capacities in an intelligent manner.  more...
     

    Preparing the electricity grid for electric vehicles and heat pumps

    The electricity grids in Germany have to be expanded to cope with decentralised generators and increasingly more large-scale loads. For grid operators it is therefore important to gain an overview of the necessary measures and their effectiveness even before installing new operating resources. Special simulation and planning tools are suitable for this. As part of the Novel E-Mobility Grid (NEMO) research project, scientists at the Fraunhofer Institute for Solar Energy Systems ISE have developed a software programme that can help to analyse and plan power grids.  more...

    Stable grid with 100 per cent green electricity

    In a power grid, the energy provided must always be equal to the power demanded. Only then can frequency and voltage remain stable. Ensuring this is the task of grid operators. But when volatile — meaning not arbitrarily adjustable — energy sources are the main sources of electrical energy, grid operators face a challenge.  more...
     

    Virtually linking mini-CHP systems

    Linked decentralised combined heat and power plants (CHP) and electric loads will be able to participate in the electricity market in the future by forming a regional and virtual power plant. This will compensate for power fluctuations and create more flexibility while being economic and efficient. The research association ‘Thermal and electric CHP linking’, coordinated by TU Dresden, presented their results.  more...
     

    Energy research on course to delivering the energy transition

    The German federal government recently published the National Action Plan on Energy Efficiency. The concept is specifically aimed at winning over all actors in society in achieving greater energy efficiency. A few days later, the German Federal Ministry for Economic Affairs and Energy announced its research funding for the German federal government’s 6th Energy Research Programme. In the BINE interview, Dr Rodoula Tryfonidou from the responsible department in the German Federal Ministry for Economic Affairs and Energy talks about the contribution made by energy research in bringing about the Energiewende – Germany’s energy transition.  more...

    Batteries in the low-voltage grid for more PV energy

    In areas where already a large number of photovoltaic systems are installed, impermissibly high voltages can occur in the power grid on sunny days. It therefore needs to be clarified how the energy generated can be optimally used both technically and economically. One idea is that new charging strategies for batteries can effectively relieve the grid by optimally integrating the energy storage systems.  more...
     

    Gas and heating networks act as energy storage systems

    Heating and gas networks can balance out fluctuations in the electricity grid. But how flexibly can surplus electricity be indirectly stored? In the Multi-Grid Storage project, scientists have investigated how it can be best of all stored in the form of heat or gas and then made available again as electrical energy as soon as it is required.  more...

    How electric vehicles can be of use to the grid

    The batteries in electric vehicles can store surplus energy from the electricity grid. By the same token, they can feed back electrical energy to the grid at times of high demand for electricity. As part of the NET-INES project, scientists are investigating different charging and discharging strategies as well as the opportunities to market this service. For this purpose, they surveyed more than 600 vehicle owners.  more...
