摘要

Conducting experiments in real-world laboratories involves inherent risks that must be identified, analyzed, and assessed. In the “Fuchstal leuchtet” research project, an island grid disconnected from the main grid is powered solely by inverters. The most significant risk factors include personnel, economic, and technical risks. Human factors have been identified as the most important factor for the successful execution of the field tests. A technical risk is compliance with power limits and energy quantities, which is a high priority in an island grid. To this end, an energy system has been developed that allows the individual components of the island grid to be simulated in a modular fashion and makes it easier to expand the system. The comparison between measured and simulated values shows larger instantaneous deviations in power, which, remain below 5% over the entire field test when considering the energy quantities transferred. This has enabled safe island grid operation with a wide variety of tests over three days. Risk management will be expanded for the next field test and is intended to develop recommendations for other island grids and the interconnected grid.
