Low-Frequency AC (LFAC) transmission systems employing power converters are being considered for a variety of applications. This work studies the small-signal stability of an LFAC transmission line controlled by the Droop Control Strategy. Eigenvalue Analysis is used to determine how the controller droop gains, operating frequency, transmission line parameters, and the operating point affect system stability. The results show that the overall system’s dynamic is governed by the sum of the droop gains of the AC/AC converters. Analytical results that give insights on how the different system’s parameters affect the critical stability point are presented. The results indicate that system stability is affected by the line’s length, the line’s R/X ratio, operating frequency and voltage.
