The shared energy storage (SES) model, as an emerging business model, optimally leverages economies of scale, leading to reduced installation expenditures [11, 12]. Researchers have delved into various facets of SES, encompassing control strategies [ 13 ], pricing mechanisms [ 14 ], management models [ 15 ], and optimal scaling [ 16 ].
Community shared energy storage (CSES) can play a crucial role in relieving the uncertainty of renewable energy resources [ 3 ]. CSES stores excess energy generated by renewable sources during low-demand periods and injects that energy during high-demand periods. Accordingly, energy storage systems can reduce the demand on
The results show that compared with no-energy storage and self-equipped energy storage, the shared energy storage mode improves the revenue of wind farm stations by 12 % and 9 % respectively.

An Optimal Hierarchical Pricing Strategy for Shared Energy Storage Services. Energy storage system (ESS) is a crucial part of intelligent grid. It plays a key supporting role in improving system efficiency. ESS has great potential applications in many scenarios, but it still.
The service price is determined by the marginal cost of the residential load aggregator, who controls the shared energy storage unit and energy supply for each consumer. Such a pricing scheme is fair to all users. Demand elasticity is also taken into account. Given the interaction between service price and elastic demand, the optimal dispatch
To tackle these challenges, a proposed solution is the implementation of shared energy storage (SES) services, which have shown promise both technically and economically [4] incorporating the concept of the sharing economy into energy storage systems, SES has emerged as a new business model [5].Typically, large-scale SES
Shared energy storage, as an emerging economic business model, provides shared services for electricity and plays a key role in storing electricity in smart parks [11]. Natural gas unit calorific value price: dollars/(kWh) 0.0356: MT capacity: kW: 50: MT heat loss rate % 5: MT heating factor % 92:
In Australia, a 420 kWh shared energy storage unit was installed for 52 households for the country''s first community energy storage trial [11]. Detroit Edison Energy, a Michigan-based energy company, installed 20 25 kWh shared energy storage units for a residential community of more than 2000 consumers [12]. 2. Literature review
A virtual energy storage system (VESS) logically shares a physical energy storage system among multiple units. In resource sharing, the distribution of benefits is a critical problem.
Peer-to-peer transactions between shared energy storage units and power grid-based suppliers, and residential consumers-based demand markets are considered. For studies on service pricing of the shared energy storage, the service price is given according to the mechanism design, such as in Refs. [32,33], the main
Pricing method of shared energy storage service. The problem to determine the service price is formulated as a bilevel optimization model. Fig. 5 illustrates the framework of the bilevel model. The upper-level problem determines the optimal SES service price of energy capacity and power capacity to maximize its profit.
The share energy storage system can help the IES reduce the investment cost, consume more renewable energy, and improve the utilization rate of energy storage. Meanwhile, the hydrogen energy storage has been applied in shared energy storage system due to its excellent characteristics in time, energy and space dimensions.
