Integrating Large Wind Farms into Weak Power Grids with Long Transmission Lines

This paper addresses some of the most significant challenges for wind generation facilities, including voltage control, reactive power management, dynamic power-swing stability, and behavior following disturbances in the power grid. It also describes wind farm control functions, including performance for controlling grid voltage in quasi-steady-state and dynamic conditions. Low-voltage ride-through characteristics, including performance following severe system disturbances. Dynamic power control functions within wind turbine-generators, including transient and dynamic performance from power swings. The dynamic performance of GE wind turbine-generators with LVRT and WFMS technology is described. The information presented includes dynamic simulation results from existing power systems with large wind farm interconnections, and actual field measurements from operating systems
