The energy management laboratory offers a space to investigate innovative energy management concepts for electricity-only household and prosumer demonstrators. The focus of the research is on prosumer behavior in the context of electromobility, the coupling of the heating and electricity sectors, load and storage management, and newly developed counting and measuring concepts. Numerous devices, such as various AC loads, DC sources, a charging infrastructure and a heat pump test stand consisting of an air-water heat pump, a climate chamber and a heating circuit can be used for this purpose. Multi-channel measuring systems from DEWESoft are used to measure the currents and voltages that occur. The power and data links between the energy management laboratory and the network dynamics laboratory also offer the option of cross-laboratory measurements. This enables the processing of new research questions and projects in the field of holistic laboratory-based research, such as the effects of a smart building on network stability.
For the central control of the electronic and thermal components, all devices are currently integrated into the ModSys-eelabs modular control environment developed at elenia. With this control environment, the user has the option of realistically reproducing a residential building that meets his requirements in just a few steps using the modular principle. Since the opening of the laboratory at the end of 2018, a prosumer demonstrator has already been set up in the NetProsum2030 project and studies have been carried out on various mobility concepts in the EnEff Campus: blueMAP project. In the future, the flexess and MELANI research projects will be processed in the energy management laboratory.
In the flexess project, the targeted use of flexibilities of technical systems in the household, tertiary, commercial trade and electric mobility fleets is examined. In this context, households with different characteristics are simulated and measured in the energy management laboratory. In the MELANI research project, measuring methods and meter concepts for the multiple use of PV home storage systems are being developed. The laboratory environment of the energy management laboratory should be used to evaluate an image of the developed concept. In addition to the research area, teaching also benefits in the form of numerous student work that can be carried out in the laboratories and the additional laboratory tests offered parallel to the lectures through the expanded laboratory environment. In addition, the extensive equipment of the energy management laboratory enables efficiency measurements of PV storage systems to be carried out in accordance with the efficiency guidelines and thus expands the service area of the institute.
