“…For low values the constraints are more stiff and the feasible space becomes fragmented. In the limit = 0 (maximum homogeneity of load split) we find that for combinations of {5, 6,10,13,14,15,22,23,24,25,26,27,28,29,30, 31} aggregators there are no optimal solutions (black dots). The reason for this is that for = 0 and, say, = 5, we are forcing to evenly distribute 32 buses among 5 aggregators so that at least one bus belongs to one aggregator.…”
