High Voltage Direct Current (HVDC) technology: An alternative means of power transmission

Energy consumption in the world is increasing, as well as the demand for efficient and quality electric power supply that ensures a greener environment. Consequently, the deployment of renewable energy sources has become imperative. The use of renewable resources like hydropower, solar and wind cannot be possible without electric transmission lines. High Voltage Alternating Current (HVAC), though an established technology of more than 100 years has its pros and cons. This paper presents an investigation into the use of HVDC technology as an alternative option for power transmission, the benefits, economic and reliability issues and most importantly, the environmental impact. In view of the crucial role played by a reliable Electric Power Transmission Grid in the economic development of nations, the integration of HVDC technology is recommended for developing countries, for neighboring countries who want to share spinning reserves and for developed countries who can tap the enormous solar and wind energies from remote deserts/offshore islands.
