TLDR
In this paper, new supervisory type control schemes can be developed to improve the performance of both the voltage regulator controllers and also the substation capacitor controllers that are used at the substations for volt/VAr control.Abstract:Â
This paper proposes new methods to improve the performance of the current volt/VAr control schemes at distribution substations. The approach makes use of the new measurement and computer resources that are now available at the substations. The paper shows that new supervisory type control schemes can be developed to improve the performance of both the voltage regulator controllers and also the substation capacitor controllers that are used at the substations for volt/VAr control. The new voltage regulator controller makes use of the voltage drop characteristics of the feeders it regulates. The capacitor controller uses local real and reactive power measurements for power factor control at the substation.read more

Fuzzy-based reactive power and voltage control in a distribution system
Ruey-Hsun Liang,Yung-Shuen Wang +1 more
TL;DR: In this paper, a fuzzy-based reactive power and voltage control in a distribution system is presented, where the main purpose is to find the combination of main transformer load tap changer (LTC) positions and capacitors on/off switching operations in a day, such that the voltage deviations at the secondary bus of the main transformer become as small as possible, while the reactive power flows through the main transformers and real power losses at feeders become as little as possible.
