Abstract：The proportion of new energy sources connected to the station area is increasing day by day，which

inevitably brings regulatory needs. Therefore，there is an urgent need for corresponding edge power flow

algorithms. In order to give consideration to accuracy，practicality and efficiency under the situation of weak

communication conditions and limited computing resources，a real-valued power flow algorithm for the edge

computing of 400 V station area was proposed. Considering the resistive nature of the 400 V station area network

and the high power factor of the equipment，the AC variables were simplified from vector sum to scalar sum；

corresponding node transformation strategies and iterative algorithms were designed ；assignment strategies in the

case of missing data was proposed；an online calculation strategy based on sensitivity correction or iterative

calculation was further proposed. Through simulation analysis，the accuracy and practicality of the algorithm

proposed were finally verified.
