The application of small polymer lithium batteries as a distributed energy storage system is rapidly expanding. The domestic lithium energy storage market is surging, and the distributed energy storage system is heating up. The heating up of the distributed energy storage market has also driven the corresponding supporting small polymer lithium battery field to warm up. Under the effect of scale, this year is expected to be the first year of the explosion of the small polymer lithium battery energy storage market.
The application of small polymer lithium batteries as a distributed energy storage system is rapidly expanding
The scale of the small-scale polymer lithium battery industry is rapidly expanding and the price is rapidly falling. The application of small-scale polymer lithium batteries as a distributed energy storage system is gradually increasing. From the current energy storage components that can be selected, small polymer lithium batteries are a more suitable choice, especially for user-side energy storage. Small polymer lithium batteries as energy storage components have advantages such as high energy density and long life. come out.
The distributed energy storage system is mainly divided into two parts: electric energy storage unit and energy storage supporting facilities. Distributed energy storage systems drive the growth of demand for energy storage small polymer lithium batteries. Small energy storage polymer lithium batteries have outstanding advantages due to their high energy density, wide operating temperature range, no memory effect, fast charge and discharge, and environmental friendliness. As production costs decrease year by year and the technological level continues to improve, small polymer lithium batteries will account for an increasing proportion of the energy storage market. It is expected that this year, small polymer lithium batteries will have a large market space for energy storage systems in microgrids and new energy applications. Up to 200MWh-500MWh.
The distributed power system is light and flexible, deployed on demand, and easy to manage. It uses small polymer lithium batteries for energy storage, effectively improving space utilization, reducing the load-bearing requirements of the computer room, extending the service life, and saving users' initial investment. Cooperating with the energy management system, it can achieve on-demand scheduling of power supply resources. Power is provided by the backup iron phosphate small polymer lithium battery pack to ensure uninterrupted power supply.
The distributed small-scale polymer lithium battery energy storage project guarantees the safe, stable and efficient operation of the entire energy storage system through real-time data monitoring and analysis, and early warning. The country is continuously promoting the innovation and R&D of the distributed energy storage industry through strong industrial policies and continuous investment. With the recent series of normal releases, the small polymer lithium battery distributed energy storage market is expected to usher in a stage of rapid development.
With a market scale of hundreds of billions, many battery companies are nostalgic for this. my country's distributed energy storage system market mainly supports photovoltaic power generation. According to the editor of Energy Storage Electric, in the domestic photovoltaic and wind power storage fields, small polymer lithium batteries account for the largest installed capacity, with a market share of more than 60%. At present, small polymer lithium batteries occupy an undisputed dominant position. Among them, 90% of the future market of distributed energy storage systems will use small polymer lithium batteries.
Main application modes of distributed energy storage power stations
Mode 1: shifting peaks and filling valleys, reducing electricity prices
Install distributed energy storage power stations on the power demand side, store electricity during low periods, and supply power to electric loads during peak periods, and use the "peak-to-valley price difference" to significantly reduce power users' electricity bills. Through investment in the construction and operation of energy storage power stations, the transferred electricity will provide users with a discount of 0.05-0.1 yuan/kWh.
Mode 2: Supplement the gap capacity
Limited by the power supply capacity of the power grid, power users often encounter the problem of insufficient power capacity, which restricts the healthy operation and development of industrial and commercial enterprises. The energy storage power station is built on the demand side to flexibly supplement the power gap capacity of users, so that users can carry out normal business or expand the scale of operations. The configuration capacity and operation mode of the energy storage power station will be designed according to the actual needs of users, and the benefits will be shared with users in a reasonable manner.
Mode 3: Emergency power supply + energy storage
It can be realized that when the external power supply fails, the small polymer lithium battery energy storage station can be used as a large-capacity backup power source to provide power for several hours to the electrical load, avoid the huge loss caused by the power failure, and effectively improve the user's power reliability . This application mode is being applied to more and more power users and has produced significant benefits.
Distributed energy storage system has unique characteristics such as strong load capacity adjustment of microgrid in the energy system network, flexible and rapid response, and most importantly, grid reform is imperative, policy promulgation and other factors are promoted layer by layer. It is a distributed energy storage system. Prepared a stage for performance. With the gradual advancement of microgrids and new energy power generation, distributed energy storage systems will enjoy a broader market.
The application of distributed energy storage technology in the distribution network, user side, microgrid, distributed power generation, etc. can produce significant economic and social benefits, and the application potential is huge. The advantages of distributed energy are in line with the adjustment of the energy structure. In the context of policy support and the declining cost of small polymer lithium battery energy storage systems, my country's distributed energy will face the market with a rapidly developing attitude.
