Abstract: The world-wide distribution of primary energy resources does not correspond to the geographical allocation of zones of their consumption. Electricity production and power-plant generating capacity grow everywhere including regions where there are no resources. Electrical power systems already cover not only individual countries, but also groups of countries, and even entire regions. Therefore, the following problem arises: is it possible and expedient to interconnect regional power systems so as to form a global energy network? The technical facilities for such a network are already available: DC transmission systems with voltages up to ± 750 kV and AC transmission systems with voltage up to 1200 kV. The transfer capacities of such transmission systems can reach 5000-6000 MW. There are no technical limitations on constructing international DC electrical transmission systems through any straits. The longest existing DC submarine cable link from Finland to Sweden along the bottom of Botnic Bay has a voltage of 400 kV and a cable length of about 200 km. The efficiency of large regional and international electrical power system interconnections between East Europe-West Europe, USSR-Canada-USA, USSR-Japan, USSR-China is to be investigated. The five countries participating in these interconnections (USA, USSR, Japan, China, Canada) generate almost 60 per cent of all the electric power produced in the world.

Keywords: global energy networks; energy consumption; primary resources; international interconnection; DC transmission systems; power system interconnections; electricity generation; power supply.
