不同耦合方式对电力信息物理系统同步的影响OA

Aimed at the synchronization problem of cyber physical power system,the influence of different coupling methods and coupling strength on system synchronization is considered.The synchronization capability of the system could be adjusted by defining the coupling mode and coupling intensity through the main stability function,and the magnitude of the synchronization capability of the cyber physical power system of five different coupling modes and the influence of coupling strength on the synchronization capability of the system were studied.The results show that the high-number-high meso-number coupling mode has the strongest synchronization ability of cyber physical power system,and the high-meso-number-high number coupling mode is the weakest,and increasing the coupling strength can improve the synchronization ability of the system.the relationship between cascade fault and synchronization capability is analyzed through simulation,and it is found that appropriately enhancing the coupling strength of the high meso-height cyber physical power system can make the system more robust and the synchronization ability stronger.
