Modern Distribution Management System and Voltage VAR Control

Development and Field Test of Voltage VAR Optimization in the Korean Smart Distribution Management System

This paper is a summary of the development and demonstration of an optimization program, voltage VAR optimization (VVO), in the Korean Smart Distribution Management System (KSDMS). KSDMS was developed to address the lack of receptivity of distributed generators (DGs), standardization and compatibility, and manual failure recovery in the existing Korean automated distribution system. Focusing on...

Distribution System Voltage Control under Uncertainties

Voltage control plays an important role in the operation of electricity distribution networks, especially with high penetration of distributed energy resources. These resources introduces significant and fast varying uncertainties. In this paper, we focus on reactive power compensation to control voltage in the presence of uncertainties. We adopt a probabilistic approach that accounts for arbit...

Voltage Control in Low-Voltage Distribution System Based on Distribution Control

Recently, LVDC (Low Voltage Direct Current) distribution system have been evolving into one of the most interesting topics in the field of distribution system due to its advantages in terms of power quality, reliability and power conversation loss reduction. Voltage control in LVDC distribution system is becoming important to improve the power quality and system reliable, it can keep voltage pr...

A Review of Voltage/var Control

This paper presents a survey of voltage/Var control techniques. It introduces both the control devices for individual reactive power sources and several popular control systems (OPRF, hierarchical voltage control, expert system and fuzzy logic) for whole power transmission network.
