DFIG-based offshore wind power plant connected to a single VSC-HVDC operated at variable frequency: Energy yield assessment
(2015-06-15)
Article
Open AccessThe existence of HVDC (High Voltage Direct Current) transmission systems for remote offshore wind power plants allows devising novel wind plant concepts, which do not need to be synchronized with the main AC grid. This ... -
Feasibility analysis of offshore wind power plants with DC collection grid
(2015-06-01)
Article
Open AccessOffshore wind power plants (OWPPs) tend to be larger in size and distant from shore. It is widely accepted that for long distances HVDC links are preferred over HVAC transmission. Accordingly, one possible approach might ... -
