             25%, 75%, or 90% of the aggregated linear load. The three cases were simu-
             lated, but in two different conditions:
               PFC kept constant on the default case (K 5 0.5) and
               PFC following the load variation.
                The plots with constant PFC are shown in Figs. 5.22 and 5.23.
