Voltage profile modification in harmonically affected power networks

Abstract

Considering importance of power quality in power systems especially in distribution systems and daily increasing application of electronic devices which are more sensitivity to quality of supplied power, improvement of quality of power is a must. Hence, in this paper voltage profile in distribution systems has been paid attention and improvement of voltage profile by various type of capacitor placement has been investigated. The effects of applying these methods on networks voltage profile have been scrutinized. These methods have been compared to each other and the best method has been selected for this affair. To achieve precise result, harmonic load flow is performed on case study that is IEEE 37 node test feeder.
