Power System Simulation Tool for Quick Benchmarking of Innovative MVDC Grids in E-Mobility Applications

The rapid development of Solid-State Transformers enables a future for microgrids that features the connection of various sources, loads, and storage elements to a common MVDC bus. The simulation of such systems present various challenges due to their growing complexity caused by the large amount of connected power converters and diversification of sources and loads. Quick benchmarking in booming areas such as E-Mobility typically require simulation models that feature superior speed with a dynamic response that fits real hardware. Within this context and objective in mind, a simulation tool has been developed with system level average models of elementary SST cells for DC grids. The implemented models are built with controlled current/voltage sources which embody dynamic behaviors of real SST systems. They may be arranged in various modular configurations, and they feature a basic failure mechanism that allows bypass of failed cells to study their impact on the full power system.
