In the current social and economic development, many countries are upgrading and transforming their energy sources, and the main reason for this is the precipitous ecological problems.

At present, many countries have achieved the carbon peak standard and are moving towards the stage of carbon neutrality. However, China has promised to achieve the carbon peak by 2030 and achieve the carbon neutrality by 2060, which means that it will only take about 30 years from the carbon peak to the carbon neutrality.

"Double carbon" background, for the development of our country has produced a great influence, and increase a lot of pressure, so under such circumstances, energy storage technology also becomes an important measure content of the current market development, and plays a very important strategic significance.

With the large-scale grid connection of random and fluctuating renewable energy and the massive access of interactive devices such as electric vehicles and distributed power sources, the power system will present the "double high" characteristics of high proportion of renewable energy and high proportion of electronic power. The power system will undergo significant changes in the balance of supply and demand, system regulation, stability characteristics, distribution network operation, control and protection, and construction costs, and will face a series of new challenges. In order to realize the load balance of the new power system with new energy as the main body, energy storage will play an important role.
