    Smart Green Tower becomes an energy producer

    The Smart Green Tower is being built in the city of Freiburg. The 51-metre-high building will provide living, residential and working space. Depending on the solar radiation, a building envelope made of photovoltaic modules generates more energy via the photovoltaic system than can be consumed directly. In order to utilise the surplus electricity, the designers are using a flexible internal energy storage system with lithium-ion batteries.  more...
     

    Adapting chlorine production to the electricity supply

    The chemical industry is the second largest consumer of electricity within German industry. Using the example of energy-intensive chlorine-alkali electrolysis, scientists are now investigating to what extent this process can contribute to managing loads in the power grid. To achieve this the production needs to be adapted to the intermittent electricity supply.  more...

    Reactive power management in practice

    The energy transition presents new challenges for grid operators. One aspect of this is the provision of reactive power. Reactive power flows in grids affect voltage and grid stability. Currently, this is primarily compensated for by conventional power stations. With the decommissioning of large nuclear power plants, the power system needs new solutions.  more...
     

    Smart Grid at favourable cost

    The same technology for decades keeping street lights illuminated has the potential to motivate power consumers and decentralised generators to adopt system-friendly behaviours. The Fraunhofer Institute for Solar Energy Systems (ISE) has investigated how dynamic power tariffs can be transmitted based on ripple control technology together with project partners. Investigations involved sending electricity market prices across the regional power grid using tariff switching times.  more...

    New administrative facility with energy-plus concept

    In 2013, the City of Freiburg held a competition for the construction of a new central administrative facility, including town hall, to consolidate its various agencies spread across the municipal area. The objective being two-fold: to produce an outstanding architectural design and to maximise energy efficiency. Monitoring measures put into effect upon commissioning are intended to reveal whether operation of the new energy-plus building fulfils the promise evident at the planning stage.  more...
     

    Multidisciplinary energy efficient production

    The closing event of the “ETA Factory” research project took place at TU Darmstadt on 11 April 2018. In the course of the project, a multidisciplinary research group was able to demonstrate the feasibility of energy savings of up to 40 percent in industrial production. The jointly planned research factory saw researchers optimise and network energy flows in production and within the building.  more...
     

    The town as a virtual energy storage system

    Scientists from industry, research and municipal companies have developed a management system as part of the “City as Storage System” project, bundling CHP plants, heat pumps, night storage heating infrastructures, PV batteries and other systems. Final field testing has shown how storage units, generators and loads in coordinated operation support the power grid as a virtual energy storage system.  more...

    Storing power and heat in the district

    Sustainable energy provision is to be developed for the urban district of Rüsdorfer Kamp in Heide. The QUARREE100 research project is investigating how the district could be fully supplied with local or regional renewable energy sources. One goal is to integrate the regionally generated wind power into the regional energy system in an economically efficient and system-serving way.  more...

    From air base to residential neighbourhood

    A new residential district is being built on the site of a former air base in Oldenburg. In addition to new buildings, some of the former barracks buildings will be preserved and converted into residential buildings. A new infrastructure concept is planned that will couple the electricity, heating/cooling and electromobility sectors and integrate them into a cross-sectoral supply network. In addition, the project partners are developing a digital service platform to provide intelligent load and procurement management at the district level.  more...

    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...
