Power hardware-in-the-loop setup for power system stability analyses

Most ongoing activities in the field of network stability support are made by pure simulation studies. In order to accelerate progresses and lower costs of design during development phases, new methods for verifying ideas and inventions have to be developed. The authors propose to utilise a power hardware-in-the-loop test bench for large-scale power system stability analysis. The advantage of this approach is that, e.g. new controls implemented for power electronic coupled generation can be directly studied concerning their impact on large-scale power system stability. This approach is shown for two different study cases; both featuring high penetration of power electronics interfaced distributed generation units in the electrical networks.
