Zhoushan Multi-terminal DC Interconnection

Description

Comprising a series of small islands, Zhoushan city, Zhejiang province, has long been suffering from poor power quality due to weak grid structure, inadequate system power flow and lack of reactive power compensation. Meanwhile, some hundred megawatts of wind power are expected to be fed into Zhoushan Grid during the next five years (the 12th five-year-plan).

C-EPRI was chosen to conduct feasibility study of constructing a 5-terminal interconnection, and paved the way for the final decision to have it materialized using VSC-HVDC technology.
