Enhancing the Algerian Power System for Long-Distance Transmission: A Comprehensive Study on the Implementation of HVDC Technology

The integration of High Voltage Direct Current (HVDC) technology into power systems has emerged as a pivotal solution for enhancing the efficiency and reliability of long-distance energy transmission. This study investigates the implementation of HVDC technology within the Algerian power system, utilizing the Power System Analysis Toolbox (PSAT) to simulate its impact on power flow and voltage profiles. The Algerian power system, characterized by its extensive geographical spread and varying energy demand across regions, presents unique challenges for energy transmission, especially from renewable sources located in remote areas. By incorporating HVDC links into the system, we aimed to address these challenges, focusing on improvements in the active power distribution and voltage stability across the network. The simulation results indicate a significant enhancement in the voltage profiles of various bus bars, which previously fell below acceptable limits. The implementation of HVDC not only brought these within the 10% voltage stability margin but also optimized the active power distribution throughout the system. These findings under score the potential of HVDC technology in bolstering the Algerian power system's capacity for efficient, reliable energy transmission over long distances, providing a valuable frame work for future infra-structure development and policy formulation aimed at sustainable energy growth.
