Redistribution of DC Power in Multi-terminal Flexible DC Transmission Systems
When there are faults in AC grid, one of the concerns is power distribution as well as system stable operation while AC grid in fixed DC voltage side goes wrong. The second point of concern is power distribution of other converter stations while certain converter station fails. Moreover, based on VSC-MTDC system balance control strategy with additional active power signal, power distribution and DC voltage control which are performed when DC voltage station fails are realized through introducing additional active power signal based on adjustable active capacity margin at fixed active power converter station so that stable operation in VSC-MTDC system can be enhanced during faults.
