The power converters of a microgrid employ a primary control responsible for sharing the power among them. This control is more demanded when the microgrid operates in islanding mode, where it is necessary to match power generation with load. The mainly control techniques for power-sharing are based on synchronous machine emulation, e.g.: droop control, virtual synchronous machine (VISMA), virtual synchronous generator (VSG) and synchronverter. Although these techniques are well-established, a comprehensive comparison is currently missing. Thus, this paper presents a comparison among such techniques considering a three-phase islanded microgrid with two parallel converters, supplying energy to three different characteristic loads. The influence of line impedances on power-sharing is also evaluated, considering five scenarios. Since the model presents a wide range of dynamic behaviors, the analysis is performed through real-time simulation using a Hardware-in-the-Loop (HIL) system. The simulation results provide valuable insights regarding the steady-state performance of the evaluated power-sharing techniques enabling the selection of the most suitable technique.
