【 摘 要 】

Energy storage subverts the traditional concept of source-network-load, breaks the inherent property of power supply and consumption at the same time. Distributed energy storage plays an important role in the energy internet. The paper introduces the technical characteristics of distributed energy storage, builds typical application scenes under the energy internet environment. Given this background, two typical operation modes of customer-side distributed energy storage are proposed based on different operational objectives and constraints. After studying the basic strategy of the operating model and evaluating the distributed energy storage economy from the perspective of users and electricity retailers, it can be concluded that distributed energy storage is able to effectively improve system flexibility and energy utilization. Its economy is determined by various factors such as technical route, configuration capacity, and electricity price. A reasonable operation mode can promote the sustainable development of distributed energy storage.
