A Harmonic Current Forecasting Method for Microgrid HAPF Based on the EMD-SVR Theory

About the micro grid power quality problem, Proposed the hybrid active power filter(HAPF) harmonic current prediction methods based on Empirical Mode Decomposition(EMD)- Intrinsic Mode Regression(SVR) theory. This method Combine the EMD and SVR, First exploded harmonic currents for each harmonic by EMD, Then using the different kernel function in SVR predict the next time harmonic currents of different times, finally, the predicted value of each harmonic weighted summation. Simulation results show that, this method can be well to improve the prediction performance.
