Stability analysis of multi-terminal HVDC with diode rectifier connected off-shore wind power plants

This paper addresses the detailed modeling and small-signal stability analysis of a multi-terminal high voltage direct current (HVDC) system including large diode rectifier-connected off-shore wind power plant (WPP). The study covers both islanded connected WPP operation with different control scenarios. Islanded stands for non-conducting HVDC rectifier (DR) whereas in DR is conducting. modes important as would be one these during normal operation. Variable ac-grid frequency dynamic model have been considered adequate modeling. proposed models validated against PSCAD EMT simulations used to carry out Moreover, assess robustness parametric uncertainties, communication delay level, ensuring integration into on-shore electrical system. also points that droop grid has larger impact on overall than controllers.
