Abstract: A phase line identification system including, at least one computer hardware device including: a first receiver that receives a plurality of times of a primary phase zero crossing for a plurality of primary phase lines at a feeder; a second receiver that receives a time of a secondary phase zero crossing for a secondary phase line at a single phase electric meter; a comparator that identifies which of the plurality of primary phase lines feeds the secondary phase line by comparing the plurality of times of the primary phase zero crossing for the plurality of primary phase lines at the feeder to the time of the secondary phase zero crossing of the secondary phase line at the single phase electric meter to determine which one of the plurality of times of the primary phase zero crossing matches the time of the secondary phase zero crossing.

Abstract: A method and system for operating a mini-grid including one or more power generation sources and one or more loads independently from a utility grid is provided, where the mini-grid is disconnected from the utility grid in response to a power disruption over the utility grid. A universal interconnect device forms a connection between the mini-grid and the utility grid. In the disconnected state, the mini-grid operates independently from the utility grid, such that the power generation sources of the mini-grid supply the loads. Frequency and voltage regulation are provided by the universal interconnect device through a monitoring function performed by a controller in conjunction with at least an energy storage device, which can absorb or generate power as needed.
