  This paper addresses the problem of managing rotational load shedding
schedules for a power distribution network with multiple load zones. An integer
optimization problem is formulated to find the optimal number and duration of
planned power outages. Various types of damage costs are proposed to capture
the heterogeneous load shedding preferences of different zones. The McCormick
relaxation along with an effective procedure feasibility recovery is developed
to solve the resulting bilinear integer program, which yields a high-quality
suboptimal solution. Extensive simulation results corroborate the merit of the
proposed approach, which has a substantial edge over existing load shedding
schemes.
