These systems are designed to store electrical energy efficiently, providing a reliable backup during peak demand or grid outages, and supporting the integration of renewable energy sources.
As a consequence, the electrical grid sees much higher power variability than in the past, challenging its frequency and voltage regulation. Energy storage systems will be fundamental for ensuring the energy supply and the voltage power quality to customers.
As a consequence, to guarantee a safe and stable energy supply, faster and larger energy availability in the system is needed. This survey paper aims at providing an overview of the role of energy storage systems (ESS) to ensure the energy supply in future energy grids.
DC connection The majority of energy storage systems are based on DC systems (e.g., batteries, supercapacitors, fuel cells). For this reason, connecting in parallel at DC level more storage technologies allows to save an AC/DC conversion stage, and thus improve the system efficiency and reduce costs.
If no reduction of the power output for upwards and downwards power control capability is considered, the only control leverage left is an accurate forecasting of the produced energy. This is not an easy task and novel methods show great improvements in the forecast accuracy to several days.
One of the major concern is to supply power during periods where both solar and wind power are not available. Long-term storage (i.e., with a discharge time at nominal power more than 10 h) plays a vital role. Long Duration Energy Storage (LDES) solutions can be divided in two categories . Inter-day LDES: Used to shift power by 10–36 h.
In the conventional approach, which involves a single power conversion stage, the energy storage system is connected directly to the DC link of the converter (Fig. 4 c). Increasing its working voltage requires larger serially-connected cell strings, leading to reductions in system-level reliability.
As illustrated in Figure 9, due to the uncertainty of photovoltaic output, there are two charging methods for the charge and discharge strategy of mobile energy storage: one is during 3:00–7:00 when the electricity price is lower, mobile energy storage utilizes grid electricity for charging; the other is during 14:00–16:00 when the load is.
Based on this, mobile energy storage is one of the most prominent solutions recently considered by the scientific and engineering communities to address the challenges of distribution systems .
Mobile energy storage systems work coordination with other resources. Regulation and control methods of resources generate a bilevel optimization model. Resilience of distribution network is enhanced through bilevel optimization. Optimized solutions can reduce load loss and voltage offset of distribution network.
Furthermore, the potential to leverage private electric vehicles (EVs) as supplementary mobile energy storage units warrants investigation. By integrating privately owned EVs into the framework, enhanced system flexibility can be achieved, particularly in scenarios where additional energy resources are limited during disaster recovery operations.
The optimal scheduling model of mobile energy storage systems is established. Mobile energy storage systems work coordination with other resources. Regulation and control methods of resources generate a bilevel optimization model. Resilience of distribution network is enhanced through bilevel optimization.
During emergencies via a shift in the produced energy, mobile energy storage systems (MESSs) can store excess energy on an island, and then use it in another location without sufficient energy supply and at another time, which provides high flexibility for distribution system operators to make disaster recovery decisions .
Therefore, mobile energy storage systems with adequate spatial–temporal flexibility are added, and work in coordination with resources in an active distribution network and repair teams to establish a bilevel optimization model.

Based Eq., to reduce the charging cost for users and charging piles, an effective charging and discharging load scheduling strategy is implemented by setting the charging and discharging power range for energy storage charging piles during different time periods based on peak and off-peak electricity prices in a certain region.
The main function of the control device of the energy storage charging pile is to facilitate the user to charge the electric vehicle and to charge the energy storage battery as far as possible when the electricity price is at the valley period. In this section, the energy storage charging pile device is designed as a whole.
