Claim 3:
4. The method according to claim 1, wherein the step S31 comprises:
1) defining a total output power of the BESS as PBSref(t) and an initial power for iterating of the BESU i as Pbi0; wherein one of the BESUs of the charging group CZ receives the total output power PBSref(t) when PBSref(t)≤0, and one of the BESUs of the discharging group DZ receives the total output power PBSref(t) when PBSref(t)>0, thereby, for the BESU i received the total output power PBSref(t), the initial power Pbi0 is expressed as follows:, P
