Voltage reactive power control based on Pub/Sub for DFIG wind farm

Point of common coupling voltage control in large wind farm is a big impact on the Grid, especially under low-connectivity environments. Publish subscribe technology is asynchronous, loosely coupling, and multi-to-multi communication, adapted to large scale distributed real-time control of the communications needs of the wind farm. This paper proposed a publish/subscribe-based real time reactive power control of transmission method. It is well used to supply the control board in the town of wind, reducing the time delay of control loops. Simulation results show that the method further improves the quality of the point of common coupling voltage control in large wind farms.
