Photo-voltaic (PV) power now is developing rapidly all over the world and China is no exception. Large-scale PV power plants have to be built in the solar resource-rich regions, which are always far away from the load center in China. Therefore, a transmission corridor must be set up to help to deliver PV power. Considering the uncertainty of PV power …
