This paper expounds the policy requirements for the allocation of energy storage, and proposes two economic calculation models for energy storage allocation based on the levelized cost of electricity and the on-grid electricity price in the operating area.
Conclusions This article studies the allocation of energy storage capacity considering electricity prices and on-site consumption of new energy in wind and solar energy storage systems. A nested two-layer optimization model is constructed, and the following conclusions are drawn:
When configuring the energy storage capacity of the system, the energy storage configuration results of the typical day with the highest demand are considered the energy storage planning standard of the system.
If is within the power supply capacity of the interconnection line, the external power grid should consider charging the energy storage system while supplying electricity; When is less than zero or greater than zero and less than , this situation mainly relies on the energy storage system to maintain the balance of .
With the increasing investment in the power grid and the construction of new power systems, the existing capacity pricing mechanism is no longer able to meet the needs of fair allocation and reasonable recovery of capacity costs. It is necessary to establish a capacity pricing mechanism that adapts to the new power system.
Using dynamic time-of-use electricity prices can more flexibly obtain the capacity configuration scale of energy storage. The article adopts the capacity and maximum power values of energy storage configuration in each season, which can meet the demand for energy storage capacity in each season.

Storage is unique among electricity types in that it can act as a form of both supply and demand, drawing energy from the grid during off-peak hours when demand is low and injecting that energy back into the grid when it is needed most. Storage is particularly useful in supporting the wide-scale integration of renewable resources, like wind and solar, because it can help smooth out …
