Voltage sag and swell affect the normal operation of loads as well as distributed generating sources and reduce the overall reliability of the system. For improving the voltage at point of common coupling, different grid code requires control of active and reactive powers through power electronic solutions. In this article, a smart power converter (SPC) is introduced in the distribution grid, and different from the existing voltage support solutions, this article utilizes control and coordination capabilities of SPC to provide medium voltage (MV) grid voltage support during voltage sag/swell. The proposed control scheme aims to improve the voltage support capability of SPC in the MV grid by the coordinated operation of SPC MV converter, low voltage converter, and battery energy storage system (BESS). For achieving the same voltage support capability, the proposed method requires lower rated BESS as compared to existing solutions. Simulation and experimental results show the effectiveness of the proposed scheme.
