The application belongs to the field of power dispatching
system automation, and discloses a
power grid dispatching
control system reliability evaluation method and
system based on a multi-dimensional state
dependency graph. The application collects node states, slice group states, service call chains,
system resource usage, and primary-
backup consistency check results and other operation
monitoring data, constructs a multi-dimensional state
dependency graph (MDDG), and unifies the deployment relationship between nodes and slice groups, the cross-node
data access relationship between nodes, the call relationship between services, the system resource competition relationship, and the primary-
backup data consistency relationship into a dependency relationship structure, so as to reflect the dependency strength between various operation entities in the distributed dispatching
control system, extend the system reliability evaluation from the traditional single-component or single-
node level to the system overall structure level, and improve the expression capability for complex distributed architectures.
