Energy Storage Operation and Maintenance Solution

Another essential factor for the optimum control and maintenance of electrochemical storage facilities is to provide the plant with a system for processing and interpreting data, issuing reports and managing alarms, both for the technical teams in charge and for customers.

At Energy Storage Solutions (E22), we have a highly specialized technical team with many years of accumulated experience in the sector, trained to design, implement, commission and provide assistance in the operation and maintenance stage of any of these subsystems.

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. (5), and when to satisfy the shiftable loads. The maintenance action considered in this work is the replacement of the ESS.

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.
