We are even Searching the Streets for
New Solutions in Energy Storage
In our effort to keep increasing the efficient capacity utilization of power supply networks in the future we are looking for new infrastructure solutions in energy storage every single day. In addition to stationary storage options, mobile solutions such as electric vehicles offer innovative technological possibilities for integrated, point-of-use power storage.
Electric vehicles as energy storage devices - Assessment of the system benefits of electricity storage with dual use
University of Strathclyde, Electronic and Electrical Engineering
With a widespread use of electric vehicle batteries, these can be used as local energy storage devices, which can absorb electricity from the network and release electricity into the network depending on the network conditions and charging state of the battery packs.
The aim of this project is to assess the system benefits of energy storage with dual use. It is necessary to take a typical vehicle’s cycle of operation into account. Different application areas of storage are being studied: frequency reserve, instant reserve, load levelling (levelling between off-peak and peak times) and the load reduction on subassemblies under high loads (distribution systems). Also looked at are load reduction in the transmission network, value creation for local power generation (e.g. from renewable energy sources that cannot be planned) and ways to complement large-scale energy production with renewable forms of energy.

Decentralised energy management - Innovative systems for storing energy – multi-agent implementation and commercial operation of distribution networks
Institute of Power Systems and Power Economics, Technische Universität Dortmund (Dortmund Technical University)
Energy storage systems significantly contribute to efficient management in distribution networks.
The project follows an innovative strategy for integrating distributed storage capacities. Linking electric vehicles creates an intelligent system of autono-mous energy storage systems. For this purpose, a non-centrally organised management system is being developed for electric vehicles and other dis-tributed energy storage systems. A multi-agent system assumes the role of automatically administrating and coordinating energy storage systems based on the DEZENT project. Furthermore, load flow calculations are performed in real time. Besides preserving conventional resources, the aim is to maximise profits for all those involved. By optimising the supply configuration, expen-diture for energy imports is reduced and the capacity utilisation of the net-works is increased.

BEST – Progressive energy storage systems - Benefits of storage systems for static applications linked with the electricity network and progressive vehicle applications (BEST project)
French National Institute of Solar Energy (INES), French Atomic Energy Commission (CEA)
Institute for Power Electronics and Electrical Drives, RWTH Aachen
The so-called BEST project examines the use of different commercially available electrochemical storage systems in mobile and static applications.
The technical data of how the storage systems work is first collected systematically. This involves an active exchange between the electricity generators and vehicle manufacturers. Accumulators with large energy storage capacity and powerful super condensers are then tested for their energy properties and life span. The combination of the two promises benefits for the storage system. Modelling how the storage system operates by applying an imped-ance-based substitute circuit diagram is planned in the third phase. Designing storage system models makes future system integration considerably easier. The results are used for technical/economic analysis and to illustrate the best storage system for every field of application.
