Abstract:

With continuous strengthening of the national environmental protection efforts, the proportion of new forms of energy power generation has gradually increased, resulting in gradual transformations in the energy structure of China. Because of the fast response rate and high adjustment accuracy of an energy storage system, it has become an important supporting method to improve the power quality and promote the consumption of new types of energy within the energy industry; it has also become the subject of increasing attention. Furthermore, the advancement of the energy storage technology (through the improvement of the product quality and continuous cost reduction) has realized its commercial application. The development of various electrochemical energy storage technologies has gradually expanded the energy storage application possibilities. In addition to technological advances, the promulgation of national policies and regulations and the deepening of power market reforms have promoted the application and support of electrochemical energy storage technologies. This study summarizes the application status of energy storage in the global power industry from a data perspective. It summarizes the development of the energy storage policies and standards of the domestic electrochemical industry and introduces the modes, technical routes, and key technology for the integration of electrochemical energy storage. Additionally, from the perspective of power generation, the use of electrochemical energy storage technology in new, large-scale grid-connected, auxiliary, and microgrid level settings is discussed in terms of the functions, policies, and application projects. Finally, the potential and development trends of electrochemical energy storage technology with respect to future energy systems are considered, and development suggestions for energy storage enterprises are proposed to promote the commercial operation and usage of energy storage.
