面向源网荷储充协同运行的故障处理方法及系统
By constructing a fault propagation phase window and an action freeze zone criterion in the source-grid-load-storage-charge coordinated operation system, the problem of overlapping and conflicting control actions caused by inconsistent subsystem response timing was solved, thereby improving the stability and consistency of the fault handling process.

AI Technical Summary
In a coordinated operation environment of power generation, grid, load, storage and charging, the inconsistent response timing of each subsystem during fault propagation leads to overlapping and conflicting control actions, causing secondary disturbances.
By acquiring operational status data and fault event data under a unified time reference, the arrival time of fault propagation in each subsystem is determined, a fault propagation phase window is constructed, the target subsystem in the propagation sensitive area is identified, and an action freeze zone criterion is constructed based on operational deviation data. The consistency debt value is calculated to sort the candidate control actions and generate a fault coordination action sequence.
It effectively reduces the time superposition conflict of control actions of multiple subsystems, reduces the risk of secondary disturbances such as voltage fluctuations, frequency deviations and power oscillations, and improves the stability and consistency of fault handling process.
