Abstract: Technologies for detecting cyber-attacks against electrical distribution devices include a controller. The controller includes circuitry to determine a first measured value of a first operational parameter of a transformer based upon one or more signals received from one or more sensors of the transformer. The circuitry is also to determine a second measured value of a second operational parameter of the transformer based upon one or more signals received from the one or more sensors of the transformer, calculate a first expected value of the first operational parameter based on the second measured value of the second operational parameter and a model of the transformer that relates the first and second operational parameters, compare the first measured value of the first operational parameter to the first expected value of the first operational parameter, and identify when a difference between the first measured value and the first expected value exceeds a first threshold.

Abstract: Unique systems, methods, techniques and apparatuses of a configurable extended interface device are disclosed. One exemplary embodiment is an interface device for coupling a power system device of a microgrid with a microgrid controller utilizing a data communication standard incompatible with the power system device, the interface device comprising three input ports configured to receive input from a power system device; a microgrid interface configured to provide output formatted according to any of a plurality of communication protocols, each being compatible with the data communication standard and configured to receive input defining microgrid configuration characteristics; data mapping logic structured to convert any of the input to output formatted according to any of the plurality of communication protocols; and parsing logic configured to parse the received input defining microgrid configuration characteristics effective to cause the data mapping logic to perform mapping of the received input to one of the plurality of communication protocols.

Abstract: Unique systems, methods, techniques and apparatuses of a power grid control system. One exemplary embodiment is a nested microgrid system comprising a first microgrid including a network controller, a second microgrid, a third microgrid, a first restoration path selectively coupled between the second portion of the first microgrid and the second microgrid, and a second restoration path selectively coupled between the second portion of the first microgrid and the third microgrid. The network controller is configured isolate the first portion of the first microgrid from the second portion of the first microgrid, calculate weighting factors for the first and second restoration paths, select the first restoration path using the first weighting factor and the second weighting factor, and couple the second portion of the first microgrid to the second microgrid using the first restoration path.
