Abstract: Multi-mode management systems are disclosed. Such systems include a first controller and a second controller. The first controller can be configured to control a power system. The second controller can have two modes. The second controller can be configured to, when in a first mode, estimate a state of the power system by monitoring communications between the first controller and the power system, and in response to satisfaction of a first condition, switch to the second mode. The second controller can be configured to, when in the second mode, disable communication between the first controller and the power system and control the power system based on the estimated state of the power system.

Abstract: This application discloses a system that may comprise at least a portion of a supply network. The system may further comprise a load controller that controls current flow with a current level of I1 into a load network that provides power to one or more loads from the at least a portion of the supply network according to a preprogrammed load curve. The system may also comprise a protection system that isolates the at least a portion of the supply network from the load controller in response to detecting a current pattern that is inconsistent with the preprogrammed load curve.

Abstract: A community DC power distribution system is provided including a community node comprising a voltage source, a first switch, and a second switch; and a power distribution loop. The power distribution loop can include power distribution lines. First power distribution lines can be grounded through first sensor resistors and electrically connected to the first switch, first local nodes, and a third switch. Second power distribution lines can be grounded through second sensor resistors and electrically connected to the second switch, second local nodes, and the third switch. The community node can be configured to provide power (i) to the first local nodes via the first power distribution lines and the first switch when the first switch is in a closed state; and (ii) to the second local nodes via the second power distribution lines and the second switch when the second switch is in a closed state.
