Inverter-based microgrid, virtual synchronous machine, stochasticoptimization, parallel tempering
Parameters of a virtual synchronous machine in a small microgrid are
optimized. The dynamical behaviour of the system is simulated after
a perturbation. The cost functional evaluates the system behaviour
for diﬀerent parameters. It is minimized by Parallel Tempering.
Two perturbation scenarios are investigated. The resulting optimal
parameters agree with analytical predictions. Dependent on the
focus of the optimization, diﬀerent optima are obtained for each
scenario. During the transient the system leaves the allowed voltage
and frequency bands only for a short time if the perturbation is
within a certain range.
