According to the latest research report from HTF MI, the value of the global high-voltage direct current (HVDC) transmission market in 2017 is 7.65 billion US dollars, and will reach 16.2 billion US dollars by the end of 2025, with a compound annual growth rate of 9.8%.
Compared to the more common AC (AC) systems, HVDC systems can use DC power for high-power power transmission. For long-distance transmission, high-voltage DC systems are less expensive and have lower electrical losses. For underwater power cables, high voltage DC avoids the large currents required to charge and discharge the cable capacitance per cycle. For shorter distances, the higher cost of the DC conversion device is still reasonable compared to the AC system due to the other advantages of the DC link.
The HVDC transmission system allows power transmission between asynchronous AC transmission systems. Since the power flow through the line can be controlled independently of the phase angle between the power source and the load, the network can be stabilized to prevent interference due to rapid changes in power. HVDC transmission also allows transmission of power between grid systems operating at different frequencies, such as 50 Hz and 60 Hz. Improve grid stability and economy by allowing power exchange between incompatible networks.
Overall, the aging of power infrastructure, increased power consumption patterns, economic uncertainty, low carbon emissions initiatives, high power quality and increased demand for reliable and stable power transmission are the main drivers for the steady and rapid growth of the global HVDC transmission market. .
