Technical FAQs 4

What is high-voltage direct current (HVDC) power distribution?

One of the promising solutions gaining traction is high-voltage direct current (HVDC) power distribution. Leveraging HVDC offers a range of benefits over conventional alternating current (AC) systems, including reduced energy losses and improved overall system efficiency.

What is HVDC power distribution?

In this blog, we will explore the intricacies of HVDC power distribution, its advantages for hyperscale data centers, and the challenges that come with its adoption. High-voltage DC power distribution involves transmitting electrical power using direct current at high voltages, typically above 1000 volts.

Can a grid-supporting HVDC system with low-voltage energy storage be applied?

The results demonstrate that the grid-supporting HVDC system with low-voltage energy storage can be applied to the grid with different short circuit ratios (SCR). The separate installation scheme addresses key challenges, such as large size, heavy mass, and integration difficulties of energy storage.

Why do hyperscale data centers use HVDC power distribution?

This makes HVDC particularly attractive for long-distance power transmission and large-scale power systems like those found in hyperscale data centers. One of the most significant benefits of HVDC power distribution in hyperscale data centers is the reduction in energy losses.
