Cyber-physical modeling technique based dynamic aggregation of wind farm considering LVRT characteristic

With the increasing penetration of wind power, large-scale integrated turbine brings stability and security risks to power grid. For aggregated modeling large farms, it is crucial consider low voltage ride-through (LVRT) characteristics. However, in aggregation methods, approximate neglect behavior essential, which leads inevitable errors process. Moreover, lack parameters practice new challenges a farm. To address these issues, novel cyber-physical method proposed. This not only overcomes problem under black-box farm but also accurately realizes error fitting according operation data. The simulation results reveal that proposed can simulate dynamic behaviors various scenarios, whether LVRT mode or normal mode.
