Abstract
In this paper, sequence impedance-based modelling is applied to two different grid-feeding converter systems, namely: (a) a converter with an inner cascaded current and power control (PQC); and (b) a converter based on the direct power control (DPC) approach in [1]. In general, impedance modelling is suitable for a systematic analysis of the robustness of different converter controls and their stability issues, especially with the benefit of being applicable to larger power networks. In this work, sequence impedance models are proposed, which do not only predict the effect of two different grid-feeding controls on system stability, but also reveal their frequency-coupling effect. The models are evaluated against each other and validated by time-domain simulations and laboratory experiments. The validity of the derived models is confirmed based on the close correlation between sequence impedance model, time-domain simulation and experimental results.
