<b>Abstract:</b><p align=\"justify\"> <br /> <br /> One of the methods to indicate the distance between studied operating point and steady state voltage stability limit (critical point) is loading margin. Complete description of operating point to critical point can be obtained from minimum loading margin.<p align=\"justify\"> <br /> <br /> To calculate loading margin, we increase load at every busses until it find critical point. Minimum loading margin found by using left eigen vector corresponding zero eigenvalue, as loading direction.<p align=\"justify\"> <br /> <br /> This research gave alternative method to calculate minimum loading margin. The proposed method utilize left singular vector corresponding minimum singular value, as loading direction to find critical point. This proposed method was applied to IEEE 5 bus and WEE 57 bus system. It was found that results of the two methods are practically the same.<p align=\"justify\"> <br />
