Abstract： |
Belonging to the distributed simulation technique area for electric system, the disclosed method includes method for partitioning interconnected power grids with borderline partitions, and distributed calculating method (DCM) for left eigenvalue and right eigenvector of power system. DCM includes designing partitioned duplex system, distributed solving equivalent network parameter, borderline compatibility equation, and eigenvector. The invention is capable of calculating eigenvector relevant to low frequency oscillation modes from each partition so as to provide important reference for low frequency oscillation issue of interconnected power grids in large scale. The calculating procedure needs only few data including state variable of exchange boundary nodes between each partition and borderline partition. The invention is suitable to distributed environment of power grids, possessing better practicability. |
