Energy storage systems (ESSs) can smooth loads, effectively enable demand-side management, and promote renewable energy consumption. This study developed a two-stage bidding strategy and economic evaluation model for ESS.
This study aims to provide rational suggestions and incentive policies to enhance the technological maturity and economic feasibility of grid-side energy storage, improve cost recovery mechanisms, and promote the sustainable development of power grids.

Independent energy storage enhances China''s energy grid stability and supports carbon neutrality goals. Despite challenges like low utilization and uncertain revenue, an economic analysis of current models and a cost-benefit model have been developed.
However, the core challenge lies in the lack of an effective cost recovery mechanism, which hampers its economic viability. To address this issue, this paper proposes a capacity compensation mechanism that incorporates

Result The application scenarios, business models and cost recovery mechanism of new energy storage on the "source-grid-load" side were sorted out, and the existing problems and policy suggestions were summarized.
We find that characteristics of high-cost hydrogen storage can be more valuable than low-cost hydrogen storage. Additionally, we show that modifying the freedom of storage sizing and component interactions can make the energy system 10% cheaper and impact the value of technologies.

Mathematical proof and the result of numerical example simulation show that the energy storage configuration strategy proposed in this paper is effective, also the bidding mode and fluctuation suppression mechanism are feasible.
However, the core challenge lies in the lack of an effective cost recovery mechanism, which hampers its economic viability. To address this issue, this paper proposes a capacity compensation mechanism that incorporates market-based revenue streams for shared energy storage.
Traditional ways to improve storage technologies are to reduce their costs; however, the cheapest energy storage is not always the most valuable in energy systems. Modern techno-economical evaluation methods try to address the cost and value situation but do not judge the competitiveness of multiple technologies simultaneously.
A traditional technology evaluation approach is to reduce the cost of its devices [ 4 ]. For energy storage, these costs can be defined as absolute costs (€), or relative to energy (€/kWh) or power (€/kW) quantities.
In general, energy storage systems can provide value to the energy system by reducing its total system cost; and reducing risk for any investment and operation. This paper discusses total system cost reduction in an idealised model without considering risks.
When new energy units are equipped with energy storage facilities, the cost of energy storage is hedged against the total amount of penalty, and the output power range increases, so the curve moves from B1 to B3.
As a result, instead of improving energy storage by minimising the LCOS, one could maximise the system-value and assess the market potential indicator. Why reducing the total system cost should also be in the interest of technology developers will be discussed in Section 4.4.
The levelised cost approaches for energy storage include metrics such as the levelised cost of storage when electricity is discharged (LCOS) and LCOH or LCOM when hydrogen or methane are discharged, respectively [ 12, 22 ]. All the levelised cost metrics above are similarly structured.
