    The implementation of an advanced control system for an eleven-level modular converter connected to the power grid via an HVDC transmission line is discussed in this study. The control system's goal is to maintain stable and dependable converter operation under a variety of operating circumstances and grid disruptions. The control system includes a number of control loops, including feedforward compensation loops for voltage, current, and power. In order to share active and reactive power between parallel-connected converters, a droop control approach is also used. Through simulation studies for various scenarios, such as changes in grid voltage and frequency, load variations, and converter faults, the control system is created and validated. The findings show that the suggested control system is capable of effectively controlling the converter's output voltage and power, suppressing harmonic distortion, and ensuring the converter's stable and dependable functioning in the face of grid disruptions. Therefore, the enhanced control method can enhance the HVDC transmission system's performance and dependability, resulting in the creation of a more effective and intelligent power grid. © 2023 IEEE.
