Battery storage system for "green2store" research project
Süwag Energie AG orders battery storage system
for "green2store" research project
Süwag Energie AG, which is headquartered in Frankfurt am Main, is permanently engaged in further development of alternative energy concepts. With the battery storage system from Siemens, the company is participating in the "green2store" project of the "Energy storage" initiative funded by the German federal government With "green2store," a consortium from the energy, IT and communications technology sectors is researching into how distributed storage systems can be operated in order to increase the capability of the grid to absorb renewable energy sources. Technical, economic, legal and ecological aspects are being studied. The research project, which has a run time of four years, has a total budget volume or more than €9 million. It is part of the "Batteries in distribution grids" project of the Energy storage initiative and is funded by the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU). The goal of this joint initiative is to guarantee consistently high supply security in Germany by 2050.
The consortium wants to develop an "Energy Storage Cloud" and apply it in a supraregional field trial. The "Energy Storage Cloud" transfers the cloud solutions familiar from information and communications technology to the energy business. Bundling a number of distributed storage systems together to create a large virtual storage system in the cloud allows storage capacities to be used far more effectively and by various participants simultaneously, independent of the individual storage locations. The research project will also undertake an economic assessment of the integrative utilization of distributed storage systems and will discuss the general regulatory framework. By researching new approaches to using distributed storage systems, "green2store" is contributing to the further integration of renewable energy forms in the electrical distribution network.
The Siestorage storage system will be one of the
largest storage elements in this virtual storage network, with a battery
capacity of about 135 kWh. Süwag Energie AG will connect the Siestorage
controller to a central control system for networked operation. The
storage battery will be available via these interfaces for higher-level
dynamic storage applications in a network with several distributed storage
systems, based on the idea of "cloud computing."
