requirements over 36 h. (B) dod status of the batteries. (C) DG output power.
• Case 2: 20% < dod < 80%
Table 8.13 summarizes the achieved results for minimum pollution analysis con-
dition for dod set range value of 20%e80%. The number of discharging cycles of the
batteries is six cycles. Table 8.14 summarizes the achieved results for minimum cost
analysis condition. The number of discharging cycles of the batteries is eight cycles.

• Case 3: 40% < dod < 80%
Table 8.15 shows the achieved results for minimum pollution analysis condition
for dod set range value of 40%e80%. The number of discharging cycles of the bat-
teries is seven cycles. Table 8.16 summarizes the achieved results for minimum cost
condition. The number of discharging cycles of the batteries is 10 cycles.
