Indices of Intermittence to Improve the Forecasting of the Voltage Sags Measured in Real Systems

This paper provides a means of forecasting the future average performance a regional electric power system in terms of sags per year based on data accumulated over a four-year period. The paper also presents statistical analyses of the measured data. The sags measured in real systems consist of both rare voltage sags and grouped voltage sags (clusters); clusters are stochastic events that must be ...
