At present, the global energy system is changing from traditional thermal power generation to an energy structure dominated by renewable energy. However, the existing power grid has limited absorptive capacity, and a high proportion of intermittent renewable energy is connected to the grid, which will not only impact the stability of the existing power grid, but may also lead to a rise in the curtailment of wind and solar power. If the power grid is equipped with energy storage, it can not only reduce the rate of abandoned wind and light, but also stabilize the fluctuation of new energy, track the planned output, and participate in the peak regulation and frequency regulation of the system to enhance the stability of the power grid. Among all forms of energy storage, lithium battery energy storage technology represented by lithium iron phosphate has significant advantages over other energy storage technologies, and is currently becoming the main installed capacity for new energy storage.
It is estimated that by 2025, the newly installed capacity of lithium battery energy storage in the global power system is expected to reach 178.4GWh, and the 5-year CAGR will be about 83%.
It is estimated that by 2025, the newly installed capacity of lithium battery energy storage in my country's power system is expected to reach 64.1GWh, and the 5-year CAGR will be about 87%.
