VSG Control of Grid-Connected Three-Level Inverter

Due to the widespread integration of power electronic equipment and renewable energy sources such as wind and solar power into the grid, grid frequency tends to fluctuate and system stability declines. This paper adopts a Virtual Synchronous Generator (VSG) approach and utilizes Space Vector Pulse Width Modulation (SVPWM) to control a three-level inverter. Compared with conventional inverters, this configuration offers superior power quality and reduced harmonic content. The proposed control strategy is verified through electromagnetic transient simulations, demonstrating its feasibility and correctness.
