In addition to its high working voltage, large energy density, long cycle life, small self-discharge rate, no memory effect, green environmental protection, step less expansion, and ability to support large-scale electric energy storage, lithium iron phosphate batteries offer a number of unique advantages. It has a good application prospect in the fields of renewable energy power station power generation safety and grid connection, network peak regulation, distributed power station, UPS power supply, emergency power supply system and so on.

1. Wind power generation, photovoltaic power generation and other renewable energy power generation safety grid.

As a result of wind power’s inherent randomness, intermittency, and fluctuation, its large-scale development will have a significant impact on power system safety. In China, where the majority of wind farms belong to “large-scale centralized development and long-distance transmission”, the rapid growth of wind power has made it difficult for large power grids to operate and control their grid-connected power generation.

Weather conditions, ambient temperature, and solar illumination intensity affect photovoltaic power generation, which is characterized by random fluctuations. As the Chinese economy continues to develop, “decentralized development, low voltage local access” and “large-scale development, medium and high voltage access” are occurring simultaneously, requiring higher levels of power network peak regulation and safe power system operation.

There is a conflict between the power grid and renewable energy generation. There is a solution to this conflict in large capacity energy storage products. Lithium iron phosphate battery energy storage system with operating mode conversion fast, flexible operation, high efficiency, safety, environmental protection, characteristics of scalability, in the national scenery storage lose demonstration project for the engineering application, will effectively improve the efficiency of equipment, solve the problem of local voltage control, improve the reliability of renewable energy power generation and improve power quality, Make renewable energy a continuous and stable power supply.

With the expansion of the capacity and scale, integration technology matures, the energy storage system will further reduce the cost, through the security and reliability of long-term test, lithium iron phosphate battery energy storage system is expected to renewable energy sources such as wind power, photovoltaic power generation power grid safety and raise the quality of electric energy is widely used.

2. Peak regulation of power grid

Pumped storage power stations are the main means of peak regulation. Two reservoirs are required for the pumped-storage power station, but their size is limited by geography. Plain areas are difficult to build in, and it has high maintenance costs and covers a large area. Using lithium iron phosphate battery energy storage system instead of pumped storage power station to cope with the peak load of power grid, not limited by geographical conditions, free site selection, less investment, less occupation, low maintenance cost, can contribute significantly to the process of adjusting power grid peak loads.

3. Stations with distributed power

The continuous and rapid development of China’s economy has brought about the decentralization of UPS power user demand, which makes more industries and more enterprises have a continuous demand for UPS power.

In comparison with lead-acid batteries, lithium iron phosphate batteries offer long cycle life, safety and stability, environmental protection, and low self-discharge rates. In UPS power batteries, lithium iron phosphate batteries will become increasingly popular as integration technology matures and costs decrease. Several power battery enterprises have developed new applications for lithium iron phosphate batteries as a result of the rise of the energy storage market in recent years. Among its many benefits, lithium iron phosphate can be transferred to the field of energy storage due to its long life, safety, large capacity, and green environmental protection, thereby extending the value chain and facilitating the establishment of new business models. In contrast, lithium iron phosphate batteries have become the standard energy storage system.

4. UPS power supply

The continuous and rapid development of China’s economy has brought about the decentralization of UPS power user demand, which makes more industries and more enterprises have a continuous demand for UPS power.

Battery made of lithium iron phosphate has a long cycle life, is safe and stable, is environmentally friendly, has a small self-discharge rate and so on. The continuous advancement of integration technology and the continuous reduction of cost will lead to the widespread use of lithium iron phosphate batteries in UPS power batteries. With the rise of energy storage market, in recent years, some power battery enterprises have arranged energy storage business, to develop new application market for lithium iron phosphate battery. As a result of its super-long life, safe use, large capacity and green environment protection, lithium iron phosphate can be applied to energy storage, extending the value chain and promoting the development of a new business model as a result. Meanwhile, lithium iron phosphate batteries have become the mainstream solution for energy storage.
