Abstract
This paper describes the Networked Energy Systems Emulation Center – DLR-NESTEC – a platform for research on power grids of the future. The DLR-NESTEC consists of a large number of networked power electronic components with which real hardware can be emulated using a real-time simulation system. The grid networking is realized via cable emulators. The laboratory works with real physical power flows and has a connected load of 800 kVA. In addition to the emulators, real network components can be integrated into the laboratory. The sector coupling is addressed by the coupling of charging infrastructure of electric cars as well as the integration of electricity-controlled heating systems. In addition, hydrogen technologies can be integrated. The laboratory is controlled by a SCADA system coupled to high-resolution measurement equipment. With the help of DLR-NESTEC, various future questions regarding robust and safe operation sector-coupled energy networks can be addressed – for instance the operation of a grid structure with a high share of controllable loads without a superordinate control.
Zusammenfassung
In diesem Beitrag wird das Emulationszentrum für Vernetzte Energiesysteme (DLR-NESTEC), eine Plattform zur Erforschung der Stromnetze der Zukunft, vorgestellt. Das DLR-NESTEC besteht aus einer Vielzahl von vernetzten leistungselektronischen Komponenten, mit denen reale Hardware über ein Echtzeit-Simulationssystem emuliert werden kann. Die Vernetzung erfolgt über Kabelemulatoren. Das Labor arbeitet mit realen Leistungsflüssen und hat eine Anschlussleistung von 800 kVA. Zusätzlich zu den Emulatoren können reale Netzkomponenten in das Labor integriert werden. Die Sektorkopplung wird durch die Kopplung der Ladeinfrastruktur von Elektroautos sowie die Integration von stromgesteuerten Heizungsanlagen adressiert. Darüber hinaus können Wasserstofftechnologien integriert werden. Die Steuerung des Labors erfolgt über ein SCADA-System, das mit hochauflösender Messtechnik gekoppelt ist. Mit Hilfe von DLR-NESTEC können verschiedene Zukunftsfragen zum robusten und sicheren Betrieb sektorgekoppelter Energienetze bearbeitet werden.
