Abstract: Building a new power system with renewable energy as the main body is an important responsibility and mission of the energy and power industry to serve carbon peak and carbon neutrality. The requirements of the power grid for renewable energy have been gradually upgraded from “friendly grid connection” to “friendly grid connection + active support”. It has become a general trend to install energy storage systems on the renewable energy side. Energy storage configuration is the front-end work in the field of energy storage application, but the cost of energy storage is still high. Therefore, the primary task is to find ways to achieve the optimal energy storage configuration. This paper reviews and summarizes the research progress of application scenarios, configuration methods, and pre-assessment methods of energy storage in the field of renewable energy both at home and abroad. Moreover, issues that need to be further considered in the energy storage configuration on the renewable energy side are proposed, and future research directions are predicted.
