Hence, distributed energy storage systems (ESS) have been considered to be a promising solution owing to their fast and flexible control capability. This paper proposes a voltage control algorithm of the distributed ESS based on the varying operating conditions of the distribution systems.
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.
To overcome this critical issue, this paper proposes a variable virtual impedance current limiting strategy that can maintain the voltage-mode characteristics of energy storage STATCOM (ES-STATCOM).
The working principle of capacitive energy storage variable voltage control strategy is explained from three cases of over-damping, critical damping and under-damping.

Energy storage batteries, with their high energy density and strong controllability, can simulate inertia effects through appropriate control strategies, providing dynamic power support during bus voltage fluctuations.
Compared with centralized energy storage, MMC-BESS can effectively reduce the voltage-level requirements of energy storage units [8]. By changing the number of energy storage SMs, the flexible configuration of energy storage capacity can be realized.
