Abstract
This paper proposes an output power control of WTG using pitch angle control connected to power systems. By means of the proposed method, output power control of WTG considering state of power system becomes possible, and in general conflicting both output power leveling and acquisition power increase are achieved. In this control approach, WTG is given output power command by fuzzy reasoning which has three inputs for average wind speed, variance of wind speed, and absolute average of frequency deviation. The simulation results by using actual detailed model for wind power system show the effectiveness of the proposed method.
