| Abstract: | Power storage technology serves to cut the peak and fill valley, regulate the power frequency, improve the stability, and raise the utilization coefficient of the grid in the power system. This paper introduces various types of storage technology such as pumped hydropower, flywheel electricity storage technology, compressed air energy storage, sodium sulfur (NaS) battery, lithium ion (Liion), Flow Battery Technology, and discusses their advantages and disadvantages. The development trend and the different applications of storage technology in the power system are also summarized. |
