Transmission of Energy on Long Distances and Ultra- High Voltage Grid

Global Energy Interconnection (GEI) is a globally interconnected strong and smart grid with Ultra- High Voltage (UHV) grids as the backbone. It is also an infrastructure platform on which clean energy can be developed, transmitted, and consumed at a massive scale worldwide. Essentially, GEI is a combination of “Smart Grid” + UHV Grid + Clean Energy”. Smart Grid integrates modern smart technologies with respect to advanced power transmission, smart control, new energy integration and new energy storage. UHV Grid is mainly composed of 1000 kV (and above) AC and +-800 kV (and above) DC transmission lines, featuring long transmission distance, large capacity, high efficiency, low line loss, less land use and high security. As the backbone grid of GEI, it is able to transmit electricity among all major clean energy bases and load canters worldwide. The result is visible in already tested in practice transmission lines of DC and AC voltage. Over 20 ultra-high voltage networks have been built in China by the end of 2019. There is one network longer than 2000 km in Brazil, and two networks of ultra-high voltage in India.
