The U.S. Electric Power Research Institute (EPRI) estimated the annual cost of outages to be $100 billion USD, due to disruptions occurring in the distribution system [12].

The size of storage technology is a dominant factor in practice.

Although using energy storage is never 100% efficient—some energy is always lost in converting energy and retrieving it—storage allows the flexible use of energy at different times from when it was generated. So, storage can increase system efficiency and resilience, and it can improve power quality by matching supply and demand.
This behaviour causes fluctuations in the system''s voltage, hampering the voltage regulation process. Battery energy storage systems (BESSs) are normally installed in power systems to mitigate the effects of these fluctuations and to control the voltage and frequency of the system [1-3]. BESSs can also be utilised to reduce the
