Analysis of Voltage Sag Assessment Based on Local Variable Weight and Grey Correlation
This paper describes a comprehensive evaluation method for bilateral voltage sags based on local variable weight and gray correlation analysis is proposed.Through the method of local state variable weight,the weight of system side indicators with different change trends is modified,and the sensitive load failure rate is calculated based on the sensitive equipment tolerance curve as the load side indicator.Based on the gray correlation analysis method,the correlation degree between the evaluation index series of each node and the reference series is calculated to obtain a more reasonable and accurate voltage sag evaluation result.
