TS Fuzzy Prediction-based SVC Compensation of Wind Farms Flicker: A Dual-UKF Approach
Fast fluctuations in wind farm power produce voltage flicker in the network. One way to mitigate the flicker is to place a static VAr compensator (SVC). Due to the operating delay of SVCs
it is essential to predict the wind farm reactive power. Here
a novel fuzzy nonlinear modeling approach is suggested and used in the one-step-ahead prediction of the power characteristics. The base of the developed fuzzy modeling is the Takagi-Sugeno fuzzy representation and a dual-unscented Kalman filter (D-UKF). In other words
a nonlinear TS fuzzy system is trained online via the D-UKF. The forecasted value is used as the SVC's reference signal. A large amount of actual data gathered from a wind farm is used for the performance evaluation. This data is collected in winter and summer for different climate situations. Using the actual data
a current source with changing amplitude and phase which is updated every half-cycle
is used to model the wind farm. Numerical results
including the flicker indices
confirm the improvement in the SVC's performance.
