Based on the poor utilization ratio and high use cost of energy storage configured on the user side, the controllability of adjustable load and the rationality of energy
An economic configuration for energy storage is essential for sustainable high-proportion new-energy systems. The energy storage system can assist the user to give full play to the regulation ability of flexible load, so that it can fully participate in the DR, and give full play to the DR can reduce the size of the energy storage configuration.
The application of energy storage system in power generation side, power grid side and load side is of great value. On the one hand, the investment and construction of energy storage power station can bring direct economic benefits to all sides [19] ch as the economic benefits generated by peak-valley arbitrage on the power generation side and the power grid
Compared with case 4, the peak load of case 5 is larger, but the investment cost of distributed energy storage is significantly reduced, which is more in line with the
Among them, load side carbon responsibility allocation based on carbon emission flow theory has been widely used and studied [10, 11]. Step 5: Calculate the system comprehensive cost including thermal power unit investment, energy storage equipment investment, wind curtailment penalty cost, transmission line expansion investment and carbon
Liu Jingkun et al. established an investment and operation decision model for cloud energy storage operators and users 8. They validated the model''s feasibility using actual load profiles and prices of local users in Ireland under both perfect and imperfect scenarios. d p r i d, z represents the distance from the small energy storage device
connection. Electrochemical energy storage (Zhang, 2013) and flexible load (Chen et al., 2018) can achieve a balance between electricity production and consumption which is why they are widely used in grids containing large amounts of renewable energy. With the rise of renewable energy, flexible load, and electrochemical energy storage

They propose that, given the prevailing technical conditions for energy storage in China and the constraints of construction costs and policy, investing in user-side
The control strategy of peak load shifting on load side based on battery energy storage technology is proposed considering the investment costs and operation and maintenance costs of battery
Aiming at the frequency instability caused by insufficient energy in microgrids and the low willingness of grid source and load storage to participate in optimization, a microgrid source and load storage energy minimization method based on an improved competitive deep Q network algorithm and digital twin is proposed. We have constructed a basic framework
Furthermore, regarding the economic assessment of energy storage systems on the user side [[7], [8], [9]], research has primarily focused on determining the lifecycle cost of energy storage and aiming to comprehensively evaluate the investment value of storage systems [[10], [11], [12]].Taking into account factors such as time-of-use electricity pricing [13, 14],
Compared with previous reviews, this paper focuses on the modeling of multi-energy coupling of each part of source-network-load-storage and modeling of the overall collaborative planning.

In the formula, C is the power supply-side investment. G is the grid side investment. L is the investment on the energy storage side. W is the energy storage side
In this stage, network-side energy storage can achieve a certain diversion of costs according to the transmission and distribution price, while the profitability of third-party investment source-load energy storage is limited by the difficulty of obtaining direct benefits from the electricity price mechanism, and the cost diversion is difficult.
Similarly, if the energy storage is built on the load side, it can play the role of earning the difference between peak and valley electricity price. Figure 1 illustrates the

Then, considering the load characteristics and bidirectional energy interaction of different nodes, a user-side decentralized energy storage configuration model is developed for a multi
Electricity bills typically account for a large proportion of industrial users'' production costs. Hybrid energy storage system (HESS), a high-performance energy storage method, has been widely used on the demand side.

With the continuous change of energy structure in recent years, the energy storage system (ESS) plays a vital role in the new power system [1].Most of the existing research is devoted to the optimal configuration or control strategies of ESS on the generation side and grid side [1], [2].Few scholars explore the economic potential of assembling ESS on the load side [3].
load-side energy storage on carbon emission is indirect and difficult to estimate accurately, Due to the high EES investment cost and insufficient peak-to-valley electricity price.
