Future DC Systems
2. DC Nano-grids
Looking beyond 2030, the challenges for electricity networks are likely to increase. Challenges treat to global security and prosperity, and there is a general consensus about them:
(i) climate change
(ii) system security
(iii) economy globalization
The situation is more and more complicate because resources across the world are becoming scarce and the need for sustainable growth is increasingly important.
Governments around the world are propitiating serious efforts towards becoming decarbonised economies as a part of a national climate change mitigation strategy. The transition to a decarbonised economy involves three main aspects:
(i) Developing energy efficiency
(ii) Developing renewable energy capabilities
(iii) Dealing with adaptation needs arising due to climate change
Future Direct Current (DC) System provide efficient way to cope with all those challenges
A nanogrid is different from a microgrid.
A nanogrid would be "indifferent to whether a utility grid is present."
It would be a mostly autonomous DC-based system that would digitally connect individual devices to one other, as well as to power generation and storage within the building.
