A research on distributed parallel calculation management mode of power system considering space-time dimensions

The decomposition and coordination calculation among multiple control centers can solve the contradiction that power systems have been interconnected while they are managed and controlled hierarchically. But distributed calculation is a complex process which involves problems about multi-regions, multi-users and multi-applications, therefore the distributed parallel calculation management mode is needed for realization. Considering from the practical point of view, this paper designs the distributed parallel calculation management mode with the decomposition-coordination mechanism, master-slave mechanism and parallel calculation mechanism. It marks the objects with time, space and application dimensional coordinates to realized the isolation and stratification of data. Therefore, it can solve the problems that applies the decomposition and coordination calculation to the reality. In addition, this paper uses distributed management mechanisms like registering, activating and calculating to manage the status of subsystems, and realizes it with hierarchical objects, forms the sequence of execution.
