VSC-HVDC

A PSCAD simulation model of direct-drive wind farm connected to the grid via VSC-HVDC is provided. Because there are a large number of power electronic devices and complex multi-time scale control links in the system, there is mutual coupling between power electronic devices or between power electronic devices and the power grid, which may lead to the risk of oscillation in the wide-band range from several hertz to hundreds of hertz.
