Frequency stability in microgrid: control strategies and analysis of BESS aging effects

In order to ensure a thorough analysis, all components placed in a microgrid would have to be considered to guarantee an effective energy management. To this aim, various algorithms are used both to preserve and restore power systems after significant disturbances. However, these models frequently do not evaluate components performance decline with the age and, consequently, they don't consider actual values during microgrid analysis, potentially affecting obtained results. In particular, evaluating energy storage systems aging and their effects has rarely been addressed in prior works. The present article proposes a model to maintain power system/microgrid stability after disturbances using a load shedding algorithm that also consider storage system aging effects. Furthermore, our scheme estimates when the microgrid system begins to suffer for the energy storage aging.
