                Abad et al. [19] investigated the HC assessment considering various
             uncertain parameters, namely, the uncertainty of the DG data resolution, the
             DG size, and the DG integration. First, the data resolution effect was exam-
             ined by considering two figures 30- and 60-minute data resolution. In the
             30-minute approach the load profile and the DG output are recorded each for
             half an hour. The authors concluded that increasing data resolution from
