Abstract

The present invention pertains to an electric energy grid connecting system and an electric energy transmission system and method, wherein the electric energy transmission system comprises: N generation units for generating N alternating currents (ACs) where N is an integer larger than 1; N rectifiers for translating said N ACs into N direct currents (DCs); and a booster for boosting the DC with a first voltage from the parallel connection of said N DCs to the DC with a second voltage for high-voltage DC (HVDC) transmission and outputting the DC with said second voltage to the HVDC transmission link for transmitting. With the electric energy grid connecting system and the electric energy transmission system and method, there is no need for diversifying the design of generation units.
