Volt/Var Control in Distribution Network: An Overview

Integration of renewable energy sources and load create challenges of economical operation of the grid at the same time power quality issues also arises. To minimize the challenges of power quality disturbances numerous research has been conducted. However very little focus is given to voltage deviation and reactive power control. Both the issue of voltage and reactive power are interdependent need to be address by a common tool. The volt-var control(VVC) concept has been adopted in existing literature which has been thoroughly addressed in this review paper. The principal goal of this study is to examine and compare existing and new approaches and algorithms for advanced VVC applications. Further, it gives the reader a thorough overview of the optimization techniques as well as objective in terms of reduction of loss, voltage deviation, energy demand reduction and minimum control variable operation.
