Comparison of decentralized voltage control methods for managing voltage rise in active distribution networks

Abstract

Integration of distributed generations (DGs) to distribution systems has posed several technical challenges for network operators. One of the main problems that has received widespread attention is the voltage rise issue. This issue has led researchers worldwide to find ways to control voltage so that an acceptable limit is maintained and delivered to consumers. In networks with DGs, the methods of voltage control have been identified as coordinated or centralized control and decentralized control. This paper presents the results and comparisons of a simulation that used these decentralized voltage control methods in managing voltage rise issues in distribution systems with DGs.
