Abstract:Island operation mode formed by UHVDC and its matching power plants is getting more common in China these years. Moreover, AC tie-line N-2 faults can force to form UHVDC island operation mode. There are many stability issues of UHVDC isolated island operation grid. This paper summarizes the latest progress and research status about real-time simulation methods, voltage stability, frequency stability, over-voltage and sub-synchronous oscillations in UHVDC isolated island grid. The features and deficiencies of present simulation modeling methods are pointed out. The related research contents of the operational characteristics and stability control methods for UHVDC isolated island grid are put forward, which can be taken as references for future research on UHVDC isolated island system.
