Hinsichtlich der konkreten Umsetzung werden in diesem Kapitel die vorläufigen Erfa...
Sensor and actor population within future smart distribution grids is much denser than within transmission grids. Thereby, future grid management systems have to cope with larger amounts of data than today's grid management systems. Also, future high-level applications for network management must be suited for use within automatic control loops. Th...
Bis 2022 will Deutschland aus der Kernenergie aussteigen und zügig auf eine Energieversorgung auf der Grundlage erneuerbarer Energien wie Wind- oder Sonnenenergie umstellen. Diese lassen sich in großem Umfang nur mithilfe von Informations- und Kommunikationstechnologien (IKT) in das Elektrizitätssystem integrieren. In einem sogenannten Smart Grid v...
The eTelligence project explores and demonstrates various smart energy grid ideas by using modern ICT (information and communications technology). For this purpose, many new and heterogeneous types of smart grid systems have to be developed and integrated, such as a regional energy market, distributed energy management systems, and an advanced mete...
Almost all core processes in energy supply companies are currently affected by dramatic changes of the basic parameters in the utilities sector. Future challenges are discussed by the example of energy management which forms a main business task in the energy supply industry.
