Abstract: The development of global energy Internet poses greater challenges to the balance of long-distance power energy supply and demand and the continued reliability of supply. Different types of energy storage technologies have advantages to solve the balance of power and electricity, and are an essential part of the development of the global energy Internet. The requirements and configuring energy storage are closely related to the characteristics and goals of specific application scenarios. This paper analyzes the characteristics and configuration methods of energy storage technology in three typical application scenarios of global energy Internet through literature research and demonstration projects,and suggests the energy storage type, power and discharge time range suitable for different applications. In view of the large-scale clean energy and long-distance transmission characteristics of the Global Energy Internet, this paper proposes a specific energy storage access topology, which provides a solution for the functional verification of simulated energy storage access to the Global Energy Internet application.
