Employing Grey System Model for Prediction of Electric Arc Furnace Reactive Power to Improve Compensator Performance

Electric arc furnaces (EAFs) are regarded as one of the major sources of voltage fluctuation in power systems which can contribute to a phenomenon known as flicker. One of the most convenient ways to mitigate flicker is employing static VAr compensators (SVCs). By employing prediction models to forecast EAF reactive power SVC performance can be improved very noticeably. In this paper a Grey system model is proposed to predict the reactive power and the efficiency of this method is investigated.
