Embodiment Construction
[0048] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0049] The present invention provides a method for calculating a distribution network load voltage sag domain and a method for identifying a voltage vulnerable area. The method includes the following steps:
[0050] Step 1): Use the structure and parameters of the target distribution network to calculate the power flow, obtain the voltage information of each bus before the fault, and calculate the positive-sequence, negative-sequence and zero-sequence impedances of the target distribution network;
[0051] Step 2): Set short-circuit faults sequentially on the target distribution network bus, thereby obtaining the residual voltage on the sensitive load bus, and based on this, obtain the bus sag identification vector BSI and the line sag correlation vector LSI;
