Abstract: A distributed power network includes a power bus infrastructure distributed over a region with node points provided to interface with controllable power nodes. Each power node can be connected to an external power device such as a DC power sources, a DC power load, or a rechargeable DC battery. The power nodes form a communication network and cooperate with each other to receive input power from DC power sources and or rechargeable DC batteries connected to the power bus infrastructure and distribute the power received therefrom to the power bus infrastructure for distribution to the DC power loads and to rechargeable DC batteries.

Abstract: There is provided an electrical assembly for use in an electrical system. The electrical assembly comprises a DC path. The DC path includes: a DC power transmission medium; and a current commutation device, the current commutation device including a switching element and an energy absorbing element, the switching element arranged to permit a current flowing, in use, through the DC path to flow through the switching element and at the same time bypass the energy absorbing element, wherein the electrical assembly further includes a control unit programmed to selectively control the switching of the switching element to commutate the current directly from the switching element to the energy absorbing element in order to increase the resultant voltage drop caused by the flow of direct current through the DC path in which the current commutation device is connected and thereby oppose the flow of the current through the DC path.
