A method of power distribution network fault voltage restoration based on grid reconfiguration

The distribution network serves as the last link directly connected to users. The power quality directly affects the user's power experience. Therefore, it is particularly necessary to keep the distribution network safe. This paper mainly studies in the case of a disconnection fault, when the reactive power optimization cannot make the voltage meet the requirements, based on the reactive power compensation, with the minimum deviation of the monitored central node voltage as the goal, a network reconstruction method is proposed. The distribution network is reconstructed, and the actual topology of a certain area is taken as an example to verify the effectiveness of the proposed method.
