Black-start control for EV's intelligent integrated station

摘要

After a blackout, power needs to be restored as quickly and reliably as possible to reduce economic loss, and consequently, detailed restoration plans are necessary. According to the basic black-start method, the control principles of black-start for intelligent integrated station (IIS) are put forward. To speed up the restoration process, the whole system containing intelligent integrated stations is partitioned into several subsystems which are restored in parallel. These independent subsystems will later be synchronized to restore the original power system seamlessly through virtual connection control. A model based on the black-start principle proposed above is developed. At last, a regional power system containing 16 intelligent integrated stations is employed as an example to verify the validity of the proposed approach.
