- Abstract
After large scale blackout, there may be more than one black-start unit in power system. A rational subsystem partitioning restoration scheme could speed up the entire system restoration procedure and promote restoration reliability. In the paper, a subsystem partitioning strategy considering the restoration reliability is proposed. The calculation of nodes restoration reliability based on the disjoint of Binary Decision Diagram (BDD) algorithm. Then according to different restoration reliability of nodes to be restored by different black-start units or charged areas, as well as its restoration time of the paths, the belonging subsystems are identified. The proposed subsystem partitioning restoration pays extra attention to the uncertainty of transmission lines and transformers which fits the practical operation conditions better. A partitioning criterion function which is solved by genetic algorithm is established to evaluate the partitioning result. Finally, the effectiveness of the proposed method is validated by IEEE 118 bus system.
