This synergistic operation favors an extended battery life. The lead-acid battery pack was proved effective in providing a sustained power for PV peak power shaving purposes, and also to limit the power ramp rate at the circumstance of exhausting the energy storage capacity of the supercapacitor.
As noted, the voltage of the supercapacitor is decreasing till time 8.36⋅10 4 s, because the supercapacitor is being discharged (is developing a positive power). At the above mentioned time, the voltage reaches the minimum admissible value, 89 V, so the battery pack is replacing the supercapacitor for PV power ramp rate purposes.
The bottom-left and bottom-right subplots then concentrates on the actuation of the battery and the supercapacitor. As noted, the supercapacitor is continuously being charged and discharged, as its energy storage capacity is rapidly exhausted.
