Abstract: Simulating complex offshore grids including connected devices and independent control algorithms (e.g. in DLL form) is essential for the assessment of global system stability. In power-electronic applications - due to independently controlled and independently switching inverters - only time domain simulation can give meaningful results. This paper presents the simulation tool VIAvento which satisfies the introduced requirements. The functioning of this tool is illustrated by showing simulation
results of connected two-point converters and one HVDC in
modular-multilevel-converter topology (MMC topology).

Abstract: Doubly-fed induction generators (DFIG) still play an important role in wind-energy applications. One of the major challenges concerning their operation is to meet not only steadystate, but also dynamic requirements. State-of-the-art DFIGs
are often controlled applying dq-control structures to guarantee steady-state power-quality requirements. The need of an exactly known transformation angle causes problems, especially under grid faults. Flux-based approaches offer more potential under
grid faults, but no current control which is essential to fulfill certain requirements under grid conditions.
A new control approach based on inverter-fixed coordinates is
presented, allowing fast reaction to dynamics and satisfying also
the steady-state power-quality requirements. The advantages of
both, current control and inverter-fixed reference frame, are combined in this control concept. Even at grid faults, the new approach provides highly dynamic behaviour which is under analysis in this paper.
