Upgrading the power grid to the Smart Grid is not child's play
·
The Electrical Engineering Association VDE warns against using the proposed and some has already started upgrading the traditional electricity grid for distributed smart grid lightly. Not the much vaunted smart grid could be created in a day, said Ingo Wolff, member of the Presidium of the VDE, the Association of the Capital Forum in Berlin. It is not enough to put "a few thousand meters of lines" or to stretch. In the background would rather delicate and complex solutions to be created.
The current debate on the energy transition is the view of the VDE over to a large extent on the core. The central challenge loud: Reconstruction and flexibility of the overall system design with the elements upgrade the network infrastructure, the storage and the power plants. The heart should constitute smart grids to integrate all actors in the electricity market by the interaction of generation, storage, network management and usage. According to the current German network development plan would have to be around 8200-km-and expanded. Until now had a year but just 20 kilometers been done.
Jörg Benze, research group leader at the VDE outlined energy information networks as the backbone of the smart grid. Including you understand all the nodes that are responsible for the transport of information in the telecommunications system and between the participants or resources of the automation system to upgrade the currently largely passive energy utilities. They did therefore provide a platform for applications and basic services, and a software interface that allow interaction with the Grid.
Currently is the central means of communication in the European energy supply system, the frequency of 50 Hertz, resulted from Benze. Case from them, this was a clear indication of the producer, that demand had increased and more power must be fed. Since only a limited number of power plants is connected, offer this demand profile of adequate statistical certainty.
With the 21 Century take the number of small energy feed-in to but, so using the information and communication technology (ICT), a distributed system must be explained by T-Systems consultant. This must also integrate the "smart consumers", seeking to avoid the peak. The benchmark rate of rich therefore to control the networks are no longer, as the participants themselves would be highly interlinked. It is to find a new steering mechanism that leads away from a linear chain, to bi-directional current flows.
Benze According to Internet Technology be adapted to these requirements and get a virtual energy marketplace. The associated new network structure allow it to operate each cell individually and as they could be regarded as part of the grid. It is not the goal of creating autonomous island networks, but a single idea. Concomitantly, stood before the energy developments in the ICT sector. The change from analogue to digital will also lead to big changes there, in which about virtual power plants would occupy more space or decide the aesthetics of an app within a few seconds on its use. Total energy information networks so forth would bring new business models.
Eric Badiqué by Directorate General Communication Networks, content and technology of the European Commission pointed out that the smart grid plays an important role for the use of renewable technologies and the achievement of Europe's energy saving goals. It must be a matter of satisfying the real-time demand for energy. Without ICT, the conversion was not to create. Would provide about ten percent of the planned new research framework program Horizon 2020, for a total of Brussels, despite opposition from some Member States up to 80 billion euros, are therefore generally intended for appropriate future technologies.
During the subsequent awards ceremony of the Information Technology Society of VDE (ITG) for outstanding publications the Grid topic took at least one of the award winners at an equally large space. Stephan Pachnicke of the company ADVA received the award for his book on the design and the dynamic operation of transmission networks. So far, the base lines for the Internet or mobile phones are designed to meet the peak load, which will usually reached in the early evening hours, Pachnicke noted in his acceptance speech. In a dynamic mode of operation, for which he had highlighted the possibility that operating costs would drop significantly, however, and resources can be saved. The corresponding potential lay with up to 50 percent less cost in the night.
