Within the scope of „grid-control – Advanced Decentral Grid Control“ industrial and scientific partners have teamed up in order to push the research, development and practical demonstration of sustainable power grids forward. This research project is part of the funding initiative „Zukunftsfähige Stromnetze“ by the German Federal Ministry for Economic Affairs and Energy and is financially supported with a total amount of EUR 10 millions. The project is carried out from July 2015 to June 2018. The goal of the project is to specify, develop, install, test and evaluate holistic concepts of sustainable power grids. Within the framework of grid-control the existing Energy Smart Home Lab will be used at KIT to investigate the provision of ancillary services in a decentralized controlled network segment. In laboratory examinations the coordination of interactive energy management systems are tested and the use of real hardware systems in critical grid situations are analyzed what cannot be done in field tests. In order to investigate decision making for capacity management applications, an agent-based energy system model for capacity management applications is being developed.
