In this paper an optimal storage-system control strategy is proposed aimed at leveling the active power requested by the loads connected to a distribution substation. The control strategy is based on a two-step procedure: first, a day-ahead scheduling is effected, and then a very short time predictive control is performed. For both the procedures, optimization models were formulated and solved including technical constraints that guarantee adequate storage-system lifetime (e.g., depth of discharge and maximum number of charge/discharge cycles). A numerical application demonstrates the effectiveness and advantages of the proposed procedure
