That''s essentially what unstable voltage does to power grids – minus the caffeine buzz. This is where energy storage systems (ESS) step in as the ultimate voltage stabilizers, acting like shock absorbers for our increasingly renewable-powered grids.
Compared with the traditional energy, energy storage power stations using emerging clean generation technology have the advantages such as peak regulation, voltage regulation, and suppressing power fluctuation of grids.
Can distributed energy storage systems regulate voltage in a distribution network? To address this problem, this paper presents a coordinated control method of distributed energy storage systems (DESSs) for voltage regulation in a distribution network.
To enhance the energy economy and scheduling flexibility of MGs, shared energy storage system (SESS) has received widespread attention as a new type of energy storage technology.
In case of distributed energy storage (DES) failure on the source side, the shared energy storage can realize DC voltage regulation and maintain system operation by reducing NCL power.
This research hypothesizes that an energy storage system integrated with MRAC can effectively regulate voltage in distribution grids, resulting in reduced voltage deviations and improved grid stability.
In response, this paper presents a distributed, event-triggered voltage regulation approach that enables power sharing across virtual energy storage systems (VESS) with different parameters while accommodating diverse time delays.
Energy storage systems (ESS) can effectively regulate voltage due to 1. their ability to absorb and release energy, 2. the inherent electrical characteristics of various storage technologies, and 3. their integration with grid management strategies.

Conversely, when it comes to voltage regulation through active power adjustment, strategies such as PV power curtailment and power-sharing techniques for Battery Energy Storage Systems (BESS) are prevalent in low-voltage distribution networks with low X/R ratios , , , .
Battery Energy Storage Systems (BESS) can mitigate voltage regulation issues, as they can act quickly in response to the uncertainties introduced due to solar PV. However, if there is no coordination between existing devices such as On Load Tap Changing Transformers (OLTC) and BESS, then BESS takes all the burden and is generally over-utilized.
Time delays inevitably pose challenges to efficient voltage regulation and power sharing.

As an effective organization form of distributed generation, microgrids (MGs) have flexible adjustment ability, which can provide voltage support for DNs.
