1. A method for controlling supply of electrical power to a mobile micro-grid power system, the method comprising:

  • obtaining power supply profile data from a plurality of power supplies operatively coupled with the mobile micro-grid power system;

    obtaining micro-grid load data associated with a plurality of electrical loads operatively coupled with the mobile micro-grid power system;

    determining a load profile for the mobile micro-grid power system based at least partially on the micro-grid load data;

    determining an active reserve power level for the mobile micro-grid power system based at least partially on the micro-grid load data;

    balancing the supply of electrical power to the mobile micro-grid power system by setting an activation state of one or more of the plurality of power supplies based at least partially on the load profile and the active reserve power level for the mobile micro-grid power system;

    receiving at least one of a load activation request indicating requested activation of one or more specific ones of the electrical loads that are currently deactivated, a load deactivation notification indicating deactivation of one or more specific ones of the electrical loads that were previously activated, and an active power supply status change notification indicating a change in a status of a currently active one of the plurality of power supplies;

    based on at least one of a received load activation request, a received load deactivation notification, and a received active power supply status change notification, automatically determining if the supply of electrical power to the mobile micro-grid power system needs to be rebalanced based at least partially on the load profile and the active reserve power level for the mobile micro-grid power system; and

    if needed, automatically rebalancing the supply of electrical power to the mobile micro-grid power system by changing an activation state of one or more of the plurality of power supplies based at least partially on the load profile and the active reserve power level for the mobile micro-grid power system.
