摘要：
In order to study the power distribution strategy of AC and VSC-HVDC hybrid system for wind power integration, a strategy based on improving the transmission capacity of AC lines and reducing the power loss is proposed. By use of the decouple control of active and reactive power of the VSC-HVDC, the transmission capacity of the AC lines can be improved by absorbing enough reactive power, AC lines have the priority before they have reached their transmission limit, meanwhile the VSC-HVDC acts as STATCOM. When the AC lines have been fully used, the VSC-HVDC will act as STATCOM as well as transmit the rest power. A DFIG wind power integration system is set up by use of PSCAD/EMTDC, the simulation results show that the power distribution strategy can realize the wind power integration successfully and reduce the power loss, it can regard as a good method for wind power integration.
