Modelling and simulation of electrical phenomena in a real time test bench

The energy transition main targets are increase of energy efficiency and promotion of renewable technologies, hence the number of components with power electronics is growing in the electrical system. The research project VEREDELE examines these effects and resulting interactions in order to identify possible challenges and develop suitable solutions. Especially active components, such as electric vehicles, pose major challenges for the modelling and simulation of these devices. The Power-Hardware-in-the-Loop (PHIL) test bed that built up is a solution to this problem and allows the integration of real devices (loads and feeds) into a grid simulation. A model library developed for system tests, which makes it possible to generate any system states to monitor the real behaviour of the equipment and to conclude on potential critical grid states. Furthermore, the characteristics of the signal source of the simulation system examined in this paper and an evaluation of the usability of the system for the intended investigations is given.
