Abstract:The “double high” characteristics of the new-generation power system make its stability face great challenges. Energy storage technology has become a key core technology to ensure the stable operation of the new-generation power system. As a typical short-time high-frequency energy storage technology, supercapacitor has the characteristics of high power, long cycle life and high security, which is suitable for power frequency regulation, voltage and inertia support, wind turbine pitch control, new energy power fluctuation suppression, vehicle-to-grid interaction and other application scenarios. Supercapacitor has become one of the important new energy storage technology routes. However, there is currently a lack of systematic research on supercapacitor energy storage application and analyses of its technical applicability in specific scenarios. This paper starts from the key issues faced by the new-generation power systems and the basic characteristics of supercapacitor energy storage, reviews the current application status of supercapacitor energy storage technology in the context of short-time and high-frequency power supplementation scenes in new-generation power systems, and uses the method of comparative analysis to illustrate the technical advantages of supercapacitors in different application scenarios, aiming to support the safe and stable operation of modern power systems and the integration of renewable energy using supercapacitor energy storage technology.
