Integration of converter-based resources into weak grids brings new concerns regarding the harmonic stability of modern power systems. This paper studies the harmonic stability and impedance characteristics of power synchronization control (PSC) which has been introduced for control of converters under weak grid operating conditions. This paper addresses this issue by studying the admittance characteristics of PSC based on the dynamics of the control scheme, the delay and the sampling frequency of the control system, and the linearized model of the grid-connected converter. Next, a critical grid inductance is derived, and necessary conditions for achieving harmonic stability are introduced. Time-domain simulations are carried out to support the proposed harmonic stability analysis.
