Abstrakt

The interaction of a grid-connected voltage-source converter with a weak grid is of significant interest. In this paper, the converter together with the grid impedance is modeled as a single-input single-output (SISO) system. Provided that certain assumptions hold, this allows us to apply the standard SISO Nyquist stability criterion for stability analysis and controller design. The derived model is verified against time-domain simulations and experiments. The method facilitates the design of the converter control system with adequate stability margins.
