Power Management Control for Battery Discharge Timing Shifts

The patent changes the control parameters of storage battery apparatuses by shifting the discharge timing parameter. Instead of discharging at the original load-following timing, the system shifts discharge timing to a later time point, allowing power reduction at the original timing while maintaining supply balance through delayed discharge. This parameter change resolves the contradiction by decoupling the timing of power balance maintenance from power reduction opportunities.

The patent applies preliminary action by shifting the discharge timing to occur before the control target period expires, rather than suppressing discharge entirely. The storage battery apparatus discharges in advance at a shifted timing, which secures baseline power during the critical period while still utilizing the storage battery's discharge capability. This maintains the merit of storage battery usage while achieving baseline power security.

The patent introduces dynamics by making the discharge timing adjustable and shiftable rather than fixed. The control system dynamically shifts the discharge timing parameter based on operational needs, allowing the storage battery to discharge at optimized times rather than strictly following load variations. This dynamic timing adjustment preserves reducible capacity while maintaining load-following performance through flexible scheduling.
