Economic Loss Assessment of Voltage Sag Based on Customer Production Scenario Identification
Accurate assessment of the economic loss of industrial customers of voltage sag is the premise of formulating the treatment plan and estimating the compensation amount.Aiming at the problems that the existing evaluation methods need to consider regarding the changing actual production scenario and limited prior data,a voltage sag economic loss assessment method was proposed considering the changes in customer production scenarios.Firstly,the transition interval was detected based on singular value decomposition and K-nearest algorithm,the power data was segmented,and the power data feature index system was constructed to accurately characterize the power data characteristics.Secondly,a power data enhancement model based on improved generative adversarial networks is proposed to improve the quality of generated data and ensure diversity by introducing feature loss,which solves the problem of limited prior data.Thirdly,the generated and prior data are mixed to construct the customer production scenario identification model and realize the effective identification of the customer production scenario.Finally,the operating state of the production line is defined according to the production scenario at the time when voltage sag occurs,and the economic loss of the voltage sag can be accurately evaluated by combining the number of industrial process interruptions and production line interruption losses in each production scenario.The effectiveness and accuracy of the proposed method are verified by an example.
