Abstract. Shared energy storage is an economic and effective way to solve the problem of renewable energy consumption. Meanwhile, sharing economy means that each energy storage operator and residential consumer can choose freely, which leads to the formation of a peer-to-peer market. This paper studies the equilibrium state of supply

Therefore, this study assumes the investor of shared energy storage system is independent to provide a more universal and practical suggestion. In this case, the optimal configuration in Case 1 is applied to explore the difference of the economic performance of SHHESS and IESs. With individual operation of IES, the costs of IES 1–3
Shared energy storage is a new energy storage business model under the background of carbon peaking and carbon neutrality goals. The investors of the
Among the new power systems built in China, shared energy storage (sES) is a potential development direction with practical applications. As one of the critical components of frequency regulation, energy storage (ES) has attracted extensive research interest to enhance the utilization and economy of ES resources through the sharing

The purpose of this study is to establish a convenient model of shared energy storage on remote islands based on comparisons between optimal individual and shared BT systems. Accordingly, we propose a unique model of shared energy storage that evolves community BTs on a small scale, which involves using sharing among
However, the existing research solely focuses on the operational strategy of multi-agent game involving integrated energy suppliers and users in deterministic scenarios, overlooking the complementary supporting role and game interaction of shared energy storage and wind farm as independent entities of interest under the instability of
The interaction between shared energy storage operators and users relies on the market structure of shared energy storage, including the sharing structure,
Shared-energy storage combines energy storage technology with shared thinking, which can break the energy exchange barriers between the supply side and the energy consumption side, provide energy storage services for multiple independent energy entities, and have significant advantages in improving system
With the promotion of carbon peaking and carbon neutrality goals and the construction of renewable-dominated electric power systems, renewable energy will become the main power source of power systems in China. How to ensure the accommodation of renewable energy will also be the core issue in the future development process of
Compared with the self-built shared energy storage system, users have better independence and flexibility when using the energy storage invested and maintained by the shared energy storage station
The shared energy storage service provided by independent energy storage operators (IESO) has a wide range of application prospects, but when faced with the interrelated and uncertain output of
Shared energy storage (SES) provides a solution for breaking the poor techno-economic performance of independent energy storage used in renewable energy networks.
Temperatures can be hottest during these times, and people who work daytime hours get home and begin using electricity to cool their homes, cook, and run appliances. Storage helps solar contribute to the electricity supply even when the sun isn''t shining. It can also help smooth out variations in how solar energy flows on the grid.
Comparison between individual and shared energy storage The individual and shared energy storage capacities and maximum charging and
Shared energy storage (SES) provides a solution for breaking the poor techno-economic performance of independent energy storage used in renewable energy networks. This paper proposes a multi-distributed energy system (MDES) driven by several heterogeneous energy sources considering SES, where bi-objective optimization and
Peer-to-peer transactions between shared energy storage units and power grid-based suppliers, and residential consumers-based demand markets are considered. A game model is proposed to characterize the market equilibrium, taking into account the strategic behaviors of individual participants. The service price is determined
The paper is organized as follows: Section 2 presents the solution approach that is composed of three steps: setting up the communities based on a clustering approach, allocating energy storage using three different methods, and optimizing of the total operational cost using a MILP formulation. Section 3 evaluates the proposed
In Ref. [31], multiple microgrids collaborated to share energy through a hybrid energy storage system, and the benefits of energy sharing were allocated based on Nash bargaining. Walker et al. [ 32 ] evaluated individual storage and SES from the perspectives of economy and operation with different parameter values to determine the
Shared energy storage plays an important role in achieving sustainable development of renewable-based community energy systems. In practice, the independent or disordered planning of community energy systems and shared storage systems can lead to suboptimal design without considering the complex interactions between
Energy storage can smooth out or firm wind- and solar-farm output; that is, it can reduce the variability of power produced at a given moment. The incremental price for firming wind power can be as low as two to three cents per kilowatt-hour. Solar-power firming generally costs as much as ten cents per kilowatt-hour, because solar farms
The concept of "shared energy storage" (SES) was first proposed in China in 2018, and refers to centralized large-scale independent energy storage stations invested in and built by third parties
An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.

The shared energy storage business model, as opposed to independent energy storage, has garnered substantial interest. Rooted in the principles of the sharing economy, these shared energy storage facilities cater to a milieu of multi-user and multi-agent collaboration, fostering a symbiotic environment.
Shared energy storage (SES) is a new ES investment concept in which multiple users jointly invest in and operate new ES equipment or cooperate to operate existing ones [15,16]. Compared with traditional ES, SES increases the profitability of a business model by separating the ownership and usufruct of ES equipment and
