Summary
The objective of this article is to compensate the deviations in magnitude and phase shift of load terminal voltage in an unbalanced low‐voltage distribution system. In specific, power balancing at the load terminal is accomplished through a compensator. A separate single‐phase full bridge voltage source converter (VSC) is employed in each phase to mitigate the system unbalance. The desired active and reactive power exchange of VSC with the system is accomplished with a simplified control methodology that considers terminal magnitude and angle measurements. The performance of the proposed method is compared with well established d‐q–based control methodology. The functionality of the compensator and its applicability is verified through a detailed case study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
