Static synchronous compensators (STATCOMs) are power electronic converters aiming at enhancing the overall power quality and system stability in power grids, by dynamically controlling the reactive power flow and reducing the voltage and current harmonics injected into the grid. In medium voltage (MV) distribution systems, step-down transformers are commonly used in STATCOMs to reduce the voltage to levels supported by the power electronic switches. Alternatively, cascaded multi-level topologies, such as the star-connected cascaded H-bridge, have been proposed to eliminate the costly and bulky transformer and thus connect the STATCOM directly to the MV grid. This article presents a simple control implementation allowing the control of the reactive power flow at the point of current coupling (PCC) using the star-connected cascaded H-bridge STATCOM. The control strategy is then experimentally validated on a scaled-down prototype using the imperix MMC bundle programmed with the ACG SDK.
