A Load Prioritization Model for a Microgrid Operation in the Islanded Mode

This work presents a load prioritization approach for a microgrid centralized-controller operating in islanded mode. The optimization in islanded mode aims to maximize the provision of the loads while following a list of priorities, which is set by the user. Controllable loads can be dragged within the priority list according to the user's preferences. Loads and groups of loads take priority among others according to their position on the list. In addition, the user may set preferences according to: the loads and groups of loads’ supply options; the amount of energy that must be saved as a backup during connected mode in order to being able to meet selected loads in an occasional islanded mode; and which loads should be automatically shut down in the islanded mode. We present a mathematical model to describe these options, as well as simulations and results.
