Analysis of Voltage Flicker due to Fixed Speed Wind Turbines

This paper presents an analysis of flicker emission from fixed speed wind turbines. Flicker emissions and power fluctuations of the wind turbines are compared in different conditions. At first, a wind farm connected to a network is considered and voltage fluctuation of that is formulated. Then, wind speed model is presented. At last, a wind farm connected to a network is simulated and flicker emission in the PCC and power fluctuations are analyzed in the Matlab/Simulink environment. In this paper, effects of variations of the following parameters are analyzed on the flicker emission and power fluctuations: 1) the line parameters; 2) the number of wind turbines in the wind farm along with wind characteristics; 3) the wind farm rated power.
