摘要: A global electricity grid may offer a number of advantages in future highly renewable energy system dominated by wind and solar power. In this paper, we provide quantitative estimates for the benefits costs an intercontinental HVDC connecting populated super regions Northern Hemisphere. The modeling is based on hourly time series power generation calculated from high-resolution weather data using Global Renewable Energy Atlas. Taking European point view, find that annual need backup can be reduced 18 to 10 % load North Africa, Middle East Russia. further reduction 7 found spanning whole Hemisphere at expense substantial increase transmission capacities. Comparing economical additional cost lines, estimate Europe its geographically nearest neighbors reduce total electricity. Longer distance connections America or Asia, other hand, would require fall 15–20 current levels.
