Final-Value Theorem: xtlim tof = 0 lim s sX s o (18) The proof of the initial- and final-value theorems can be approached by invoking (14) and is left as an exercise (see §12.9 if you need help on this). Table 2 lists some common properties of the unilateral La-place transform and the initial- and final-value theorems.
Although using energy storage is never 100% efficient—some energy is always lost in converting energy and retrieving it—storage allows the flexible use of energy at different times from when it was generated. So, storage can increase system efficiency and resilience, and it can improve power quality by matching supply and demand.
