Analysis of the Impact of Reactive Power Control of Energy Storage Equipment on Voltage Stability

Energy storage devices play an important role in promoting the consumption and safe and stable transmission of renewable energy. In the case of weak power grid strength, the reasonable setting of reactive power support capacity of energy storage equipment can economically and efficiently provide voltage support capacity. This article conducts mechanism analysis from the perspectives of static and dynamic voltage support capabilities. Secondly, the characteristics of support capabilities are analyzed in detail based on typical power grid parameters. Finally, the role of reactive power support capabilities of energy storage devices is verified through actual power grid examples.
