The weakness of the grid is generally defined according to the short circuit ratio (SCR). An AC power grid is weak when 2 < SCR ≤ 3 $2 &lt; {rm {SCR}} le 3$, and very weak when SCR ≤ 2 ${rm {SCR}} le 2$ [4, 5]. The weak grid has posed a serious challenge to the stable operation of grid-connected inverters .
