Parallel Restoration Partitioning Method for Power Systems Based on Improved Cluster Percolation Method
The parallel restoration of the power system is of great significance to accelerate the recovery of the system after the power outage,and reasonable and effective system division is the primary prerequisite for parallel recovery.Based on this,this paper proposes a hybrid integer linear programming model with improved faction filtering,which can quickly divide the system.Firstly,the corresponding number of zones is obtained according to the position and number of black-start units in the system,and then the adjacency matrix of the power grid is constructed by considering the power flow information on the line before the power failure.Secondly,in view of the defect that the classical faction filtering algorithm can't divide individual nodes outside the faction,the paper constructs a mixed integer linear programming model based on faction definition,so that the nodes in the system can be effectively divided.At the same time,in order to speed up the solution speed,the topology map simplification principle is used to simplify the system.Finally,IEEE 39 bus system,IEEE 118 bus system and an actual system examples are used to verify the effectiveness of the proposed method.
