, , and of the WPPs at 10.5 m/s, 0.5° wind: (a) power factor = −0.95, (b) power factor = 1, and (c) power factor = 0.95. The three equivalent WPPs built based on crowbar conduction, incoming wind, and speed vector of generator are in red dash, blue dot, and magenta dash dot, respectively, and the detailed WPP is in black solid.
