Method to Estimate Expected Sag Frequency Considering the Operating Condition of Power System Son, Jeongdae; Lee, Kyebyung; Park, Chang-Hyun;
This paper deals with the assessment of voltage sags regarding the variation of system operating conditions. In general, voltage sag assessment is performed by assuming the constant operating condition throughout the year. However, the assumption can lead to assessment errors in case of considerable changes of system operation condition. This paper presents a method to estimate ESF(expected sag frequency) considering the operating conditions according to the changes of power demand throughout the year.
