摘要：

To satisfy different dynamic performances for energy storage grid-supporting inverter in both stand-alone (SA) and grid-connected (GC) states simultaneously, the new improved droop control (IDC) strategy is proposed. The control strategy is designed through combining with the virtual synchronous generator (VSG) control, and it incorporates a novel adaptive control. The IDC has good power tracking ability without large overshoot or oscillation. What is more, the IDC has the ability to afford sufficient damping properties, virtual inertia, and it has faster response speed. Moreover, the IDC improves the shortcomings of droop and VSG control. It has excellent performance under both the GC and SA states. In the end, the correctness of proposed control strategy is proven through the control hardware-in-loop (CHIL) experiments.
