Advanced AC-DC power flow analysis: evaluating the impact of control parameters on system performance

The paper addresses the challenges posed by the increasing integration of Direct Current (DC) transmission lines and system controllers into power systems. It presents a novel AC-DC load flow methodology designed to resolve the limitations of traditional AC-only models. The methodology integrates traditional AC load flow techniques with tailored DC system models to better address the complexities of mixed AC-DC networks. The proposed methodology, utilizing the Newton-Raphson algorithm, systematically evaluates performance by comparing it with conventional AC-only models and other hybrid methods through detailed test cases. The results show that the AC-DC load flow method significantly enhances both the accuracy and computational efficiency of power flow calculations. By effectively addressing the complexities of integrating AC and DC components, this method offers a robust and innovative solution for modern power system analysis, representing a notable advancement in the field.
