The power-distribution network may include a first portion (26) with one or more power loads (34) connected thereto and a second portion (28) with one or more power loads connected thereto. The method may include repeatedly executing a load-priority cycle including operating in a first load-priority mode and subsequently operating in a second load-priority mode, during a power deficit. Operating in the first load-priority mode may include supplying power to the first and second portions of the power-distribution network, with a priority on supplying power to the first portion. Operating in the second load-priority mode may include supplying power to the first and second portions of the power-distribution network, with a priority on supplying power to the second portion.
