Electrochemical and other energy storage technologies have grown rapidly in China. Global wind and solar power are projected to account for 72% of renewable energy generation by 2050, nearly doubling their 2020 share. However, renewable energy sources, such as wind and solar, are liable to intermittency and instability.
One key advantage of chemical energy storage, especially energy storage via green ammonia, is that long-term storage is particularly cost-effective [15], [17], [34]. In order to consider the effects of long-term storage using the proposed formulation, the time horizon of each operational scenario would need to span multiple months.

Presented comprehensive configuration schemes for two energy system scenarios. energy storage can also be used in cooperation with other clean energy supply equipment. be divided into: (9) min C anc = min C inv + C op where C anc is the total annual cost, yuan; C inv is the annual investment cost of energy storage
Pumped hydro makes up 152 GW or 96% of worldwide energy storage capacity operating today. Of the remaining 4% of capacity, the largest technology shares are molten salt (33%) and lithium-ion batteries (25%). Flywheels and Compressed Air Energy Storage also make up a large part of the market.
The shared energy storage of the new energy power system should be able to meet the regulating demand in multiple scenarios. However, the demand in multiple scenarios is coupled, which makes the existing operation strategies difficult to apply. It restricts the large-scale development of shared energy storage. So, this paper proposes the cooperative

A case study shows that the proposed hybrid storage coordinated operation strategy can effectively improve the wind farm income and the accommodation of wind power.
In scenario 2, energy storage power station profitability through peak-to-valley price differential arbitrage. The energy storage plant in Scenario 3 is profitable by providing ancillary services and arbitrage of the peak-to-valley price difference. The cost-benefit analysis and estimates for individual scenarios are presented in Table 1.
Scenario settings. Whether the energy systems cooperate or not is one of the most important factors that affects efficiency. And P2G is vital in terms of clean energy consumption as well as in increasing the income. Therefore, multiple scenarios are set up with energy system and P2G as variable factors. The details are as follows: Case 1
