Abstract
The invention relates to a parallelization method for black-start subsystems of a power grid with external support, which includes, after power blackout, partitioning the power grid into subsystems, and respectively performing black-start on the subsystems based on a power grid black-start research scheme, performing stability check on each subsystem, performing voltage calculation on parallel lines between the subsystems, checking the parallelizing simulation of the subsystems, and determining a feasible parallelizing path and a recommendable charging direction. The method further includes, starting from the subsystems having external support and higher stability, networking them with an external power grid, parallelizing the networked subsystems having external support to obtain a subnet of the subsystems, parallelizing subsystems having no external support with the subnet of the subsystems to obtain a regional subnet, and finally parallelizing the remaining subsystems with the regional subnet to implement parallelization of black-start subsystems of the whole power grid.
