This study describes an enhanced hybrid method for calculating the periodic steady state of radial and weakly meshed distribution networks. The forward/backward sweeping technique has been taken here as basis to compute the network's equilibrium, accounting that non‐linear elements and electronic devices are included. On one hand, a modified harmonic domain (MHD), based on the discrete Fourier transform (DFT), has been used to account for harmonics and interharmonics simultaneously, involving only matrix/vector operations. On the other hand, non‐linear elements and electronic devices are handled in the time domain and included in the sweeping solution scheme by interfacing MHD and time domain through DFT operations. The proposed hybrid sweeping‐based technique and a Newton‐based method are compared here through a network example.
