Why is DC power important?
DC power has significant and inherent advantages in realizing both decarbonization and resilient grids, due to DC’s higher “potential” for electrical power diversification, decentralization and naturally improved transmission efficiency. MVDC is essential for delivering renewable energy to the consumer.
Why should we convert power systems to DC?
In addition to preventing energy loss through AC/DC conversion, converting related power systems to DC will strengthen the resilience of the region by forming a DC grid that allows power to be shared with adjacent facilities and communities.
Which data centres will be the first to convert to DC?
The assumption is made that data centres with a large number of DC-using equipment will be the first to convert to DC. Starting from the DC data centre, the entire city block, including surrounding facilities and buildings, will be converted to DC, thereby reducing energy loss throughout the region (see Figure 11).
Why is LVDC so resistant to DC?
Resistance to DC, in particular LVDC, essentially stems from commercial concerns, i.e. established AC systems and grid providers, rather than as the result of any bona fide technical aspects that would otherwise prevent DC/LVDC from being deployed across a greater range of uses.
Is DC a viable alternative to AC?
DC will dramatically reduce the costs of installation complexity: smaller cable diameters (in comparison to the conventional AC) transported on longer distance with less losses. The example of sustainable public lighting is already a reality in The Netherlands. The provincial road N470 (see Figure 13) is a project which involves multiple partners.
