Abstract:

Distributed storage system is becoming more and more widely used in power users side. The Distributed storage system has a variety of application scenarios and it is a potentially good resource for power grids. However, it has the following problems the capacity of small quantity, uneven distribution, high cost of stand-alone access, system operation and management difficulties. These problems have brought serious challenges and technical problems to the planning and operation of power grid. This paper introduces the typical application mode and access mode of distributed energy storage on user side. The application mode and scheme of distributed energy storage under different application scenarios are described in this paper. We give the distributed energy storage effect in typical application scenarios. The analysis of the technology form and carrier of distributed energy storage will provide theoretical guidance for further research on distributed energy storage coordination control technology.

Key words: distributed energy storage, electric power user side, application mode, clustering energy storage, coordinated control
