MATLAB Simulation of Lightweight High-Voltage DC Transmission Systems

In this study, we conduct comprehensive MATLAB-based simulations of lightweight high-voltage direct current (HVDC) transmission systems, combining theoretical analysis with practical modeling approaches. Our simulation framework implements key system components including power converters, DC cables, and control strategies using MATLAB/Simulink blocks. The modeling process involves developing mathematical representations of voltage source converters (VSCs) and implementing pulse-width modulation (PWM) control algorithms through MATLAB scripts. We analyze system dynamics through transient stability simulations and power flow calculations using specialized functions from MATLAB's Power Systems Toolbox. The research examines critical performance indicators such as harmonic distortion levels, power transmission efficiency, and fault response characteristics. Our implementation includes custom MATLAB functions for parametric optimization and sensitivity analysis, enabling comparative evaluation of different system configurations. Through this simulation-based investigation, we assess both the advantages and limitations of lightweight HVDC systems, particularly focusing on their applications in renewable energy integration and electric vehicle charging infrastructure. The study contributes to the development of efficient simulation methodologies and provides insights for system optimization in modern power transmission applications.
