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

Abstract

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. This advanced hierarchical control of both real and reactive power output can provide dynamic performance that is, superior to that achievable with modern conventional synchronous generation. This paper 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 for power swings
