主　　题：Frequency stability 

摘      要：To prevent large-area blackouts due to excessive frequency drop, Under-Frequency Relay (UFR) is employed to automatically disconnect loads. Recent changes in the characteristics of the power grid, such as variations in power consumption patterns and increases in pv generation- can lead to increased deviations in the amount of load shedding, potentially affecting the reliability of UFR operation. To address this issue, it is necessary to analyze the adequacy of the load shedding quantities at each UFR stage and develop an operational system for UFRs that ensures frequency stability and optimal load shedding through frequency simulations. © The Korean Institute of Electrical Engineers.
