N2 - This article proposes a methodology for analyzing and designing Andronov-Hopf (AH) dispatchable virtual oscillators (dVOC) Grid-Forming (GFM) control methods. With the proposed methodology, four existing dVOC methods are reassessed and new insights on their structures are provided. Furthermore, a unified parameterization procedure is developed so that the inverter's steady-state behavior follows a prescribed droop behavior. Controller-Hardware-in-Loop results show that when applying the proposed parameterization with the same droop objectives, the analyzed dVOC methods presented, on one hand, similar dynamic behavior responses and the other hand, different steady-state droop behaviors. The proposed methodology may also be used to design AH dVOC GFM control methods, where main design criteria is the specification of output droop behavior of the grid-forming inverter.
