Abstract: Nonlinear loads introduce harmonic pollution into electrical distribution networks, degrading power quality, increasing losses, and causing equipment malfunction. This paper presents an active power filter based on a Modular Multilevel Converter (MMC) with four submodules per arm (N = 4) and an 800 V DC-link voltage, designed to compensate grid current harmonics caused by nonlinear loads. Two control strategies are studied and compared: Nearest....
