Contrary to other proposed approaches, the present work aims at defining an energy management strategy that is able to cope with the main issues of MGs equipped with ESS, i.e., ESS degradation and unexpected outages of the main grid, which can be appreciated only considering long time horizons.
The operation actions concern the management of the ESS charging and discharging, which, in turn, determines the amount of energy that will be bought or sold to the main utility grid according to the energy balance in Eq.

A maintenance intervention can be performed to deal with ESS degradation. It consists in the replacement of the ESS to restore its capacity to the as good as new condition.
As a consequence, the performance of the method in terms of unmet demand is unsatisfactory, which penalizes the approach in terms of objective S. Also, notice that the slight improvement in terms of unmet demand with respect to the baseline is due to the presence of an ESS that improves the reliability of the system in case of grid outages.
