Analysis of DC Grid Technology Based on Large-Scale Renewable Energy Access
DC grid technology is an effective solution to the problem of large-scale renewable energy access in China.In view of the stability problem for large-scale renewable energy access to traditional AC power grid,this paper proposes using DC grid to develop large-scale renewable energy in China,referring to the international research of DC grid technology,and analyzing the features and applicability of DC grid.Then combining with the actual geographical distribution of Chinese energy and load,this research probes into China's future development mode of renewable energy,and points out the key problems to be solved urgently for present DC gird.
