This article highlights the key components of a multi-infeed voltage source converter (VSC)-based high voltage direct current (HVDC) system with modeling and simulation of a fractional order PI (FPI) controller. Due to their fragmental characteristics, fractional-order PI (FPI) controllers are more durable than PI controllers in multi-infeed VSC HVDC (MiVDC) systems. The FPI parameters significantly impact the controller's performance, and they must be set optimally. The Teaching-Learning-Based Optimizer (TLBO) is recommended. With frequency domain analysis, detailed modeling and design of LCL filters are presented. Line and converter current and voltage control are analyzed, and PI, FPI, and TFPI controllers have been designed. Due to the proposed approach's superior performance in terms of voltage stability for a variety of power system control applications, comparative simulation results with tables are used to support the possibility of real-time application.
