Abstract

The high volatility caused by the intermittent nature of wind power generation adds uncertainty to power grid systems. Herein, we analyzed the characteristics of domestic wind power output by focusing on the volatility of capacity factors. Initially, the average characteristics and the number and duration of ramps, which are representative measures of the volatility of the capacity factors, were analyzed by year and month, using the data for 2018 ~ 2022 with a temporal resolution of 1 h. Subsequently, we generated data at various resolution levels using the 2019 data with a temporal resolution of 5 min and analyzed how the number and duration of ramps were affected according to the resolution. The results showed that the frequency and duration of ramps strongly depended on the time resolution of the data, and that evaluating and considering ramp characteristics can assist in enhancing the flexibility of power system operations by mitigating rapid ramp events.
