Research on Local Topology Intelligent Reconfiguration to Reduce the Operation Risk of Unban Power Network

Abstract

With the increasing scale of urban power network, higher requirements are put forward for improving power supply reliability and ensuring the safe and stable operation of power network. Various kinds of power network security work is also moving towards a more intelligent direction. In order to prevent the substation from losing voltage in the N-1 state, the identification method of the maximum possible transfer area, the power supply loop search method and the BPSO algorithm are proposed to reconfigure the local topology of the network. The validity of the proposed method is verified by the actual power network.
