Tuning of the PI Controller Parameters of a PMSG Wind Turbine to Improve Control Performance under Various Wind Speeds

Kim, Yun-Su; Chung, Il-Yop; Moon, Seung-Il - In: Energies 8 (2015) 2, pp. 1406-1425

This paper presents a method to seek the PI controller parameters of a PMSG wind turbine to improve control performance. Since operating conditions vary with the wind speed, therefore the PI controller parameters should be determined as a function of the wind speed. Small-signal modeling of a...
