I decomposed a time series power signal using 2 decomposition methods Variational Mode Decomposition (VMD) and Discrete Wavelet Transform (DWT) and got sub-series signals (low and high frequency) and used each sub-series signal to forecast/predict the sub-series power.
How can I reconstruct/add the forecasted sub-series signals to get the final forecated power value?
Is there a function to do this on MATLAB?

You can use the “waverec” function for this purpose.
Follow the following documentation for more details.
