Abstract: The design of energy storage is one of the important issues in MicroGrid planning, The reasonable choice and capacity design of storage equipments are both important issues. This paper presents the design methodology of energy storage based on Ragone curve of energy storage device. Firstly, the Ragone curve is introduced, the method of drawing a Ragone curve which is based on the mathematical model of energy storage device is proposed. And then the design methodology of energy storage is presented in this paper. Finally, taking a CFM200 battery as an example, how to choose reasonable storage equipments in MicroGrid based on Ragone curve is introduced.
Key words: MicroGrid; energy storage technology; design of energy storage; Ragone curve
