Advancements in Microgrid Voltage Control Schemes

Due to the intermittent behaviour of the renewable energy sources, containing the voltage rise issues and maintaining voltage regulation throughout the microgrids is of paramount importance. This paper presents a detailed literature survey on the available voltage control schemes. A unique approach for classifying and analyzing the voltage control techniques of active distribution system and/ or microgrid, on the basis of their time scale, is proposed as short term voltage control and long term voltage control. Various architectures of their field implementation as decentralized, centralized and distributed are reviewed and discussed. Furthermore, the future trends in the voltage control are also reported.
