Coordinated economic dispatch of AC/DC hybrid microgrids considering energy storage degradation

AC/DC hybrid microgrids have gained more attention due to the increase of DC power source and loads. Therefore, the coordinated dispatch is necessary for economical and reliable operations of AC/DC hybrid microgrids. In this thesis, the hybrid DC/AC microgrid is modeled in MATLAB by constructing...
