Black-Start Subsystem Partitioning Based on Nodes Voltage

Abstract:

Divide the network into several subsystems then restore the subsystems separately can accelerate the restoration procedure after a main blackout occurs. In this paper, the strategy of black-start system partitioning based on nodes voltage is proposed. The strategy considers the node voltage as partition criterion. By power flow calculating gets nodes voltage and sorts them and then select voltage threshold to partitioning the groups of the nodes according to nodes voltage and the number of black-start units. The algorithm has a rigorous theoretical basis for it based on communities finding theory of complex network. The effectiveness of the proposed method is validated by studying the IEEE 118-bus case.
