Model Predictive Integrated Voltage and Frequency Support in Microgrids.
Proposed for presentation at the The 52nd North American Power Symposium held April 11-14, 2021., 2021 For the optimal performance of a microgrid where line resistance to reactance (R/X) ratio is high, one must consider the coupling between voltage and frequency. Furthermore, microgrid operational costs are time-varying. Thus, the voltage and frequency support controller must be flexible enough to handle technical and economic constraints. In this paper,

A voltage sag supporter utilizing a PWM-switched autotransformer [PDF]
2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004 This paper describes a novel distribution-level voltage control scheme that can compensate voltage sag and swell conditions in three-phase power systems. Faults occurring in power distribution systems or facilities in plants generally cause the voltage sag or swell. Sensitivity to voltage sags and swells varies within different applications.
