The power system is divided by voltage levels, and its power flow should flow within the same voltage level as much as possible. Power systems with different voltage levels need to develop energy storage. It is not only important to focus on the construction of centralized large energy storage stations in high-voltage power systems, but also to pay attention to the development of energy storage on the user side.

(1) Policy issues

From the above data analysis, it can be seen that the cost of user side energy storage is relatively high, and encouraging the development of user side energy storage requires certain policy support and subsidies. When the capacity of clean energy power generation expands to a certain stage, it is necessary to pay attention to the synchronous growth of energy storage capacity.

(2) Management issues

The increase in energy storage capacity on the user side will bring new changes and challenges to the scheduling of the power grid. User side energy storage is distributed energy storage, which can greatly reduce the number of large energy storage stations by fully allocating user side energy storage. While ensuring the safe operation of the power grid, it can achieve optimal economic benefits.

(3) Technical issues

Energy storage batteries have the advantages of fast response speed and easy modular production, but they also have a disadvantage, as their charging and discharging times determine that energy storage batteries are consumables. Improving the utilization rate of energy storage batteries and reducing production costs can be approached from three aspects: improving production processes, optimizing charge and discharge management procedures, and developing energy storage battery recycling and reuse technologies.
