As the demand for energy storage on the grid side gradually increases, the flexible regulation capability of energy storage power stations becomes more and more important. The management and control technology of unattended energy storage power stations has the advantages of high efficiency, fast processing speed, and low labor cost, and is being vigorously promoted and applied. This paper firstly expounds the relevant policies and status quo of grid-side energy storage power station grid-connection and control, and then, sorts out the data processing technology of unattended energy storage power station and its intelligent optimization control strategy. Finally, the future direction of the intelligent control strategy for unattended grid-side energy storage power stations is prospected.
