The large-scale integration of wind power generation may deteriorate the power system stability. For example, transient stability can be adversely affected by unscheduled power flow conditions caused by wind power generation. In order to address this problem, it will be a promising way to use an event-based wide-area control system (WACS) with advanced information and communication technology. In the present paper, we develop a novel method that controls active and reactive power of variable-speed wind power generation by WACS for transient stability improvement. Numerical simulation results show that the proposed active power control method improves the transient stability. In addition, the results indicate that coordinated control of the active and reactive power by the proposed method has synergistic effects for transient stability improvement.
