    Abstract: Systems, methods, techniques and apparatuses of power network control are disclosed. One exemplary embodiment is a power network comprising a plurality of zones each including a plurality of measurement devices structured to measure electrical characteristics of the corresponding zone, a zone controller structured to receive measurements from the plurality of measurement devices, a distributed energy resource (DER), and a load. Each zone controller is structured to receive a set of local measurements from the plurality of measurement devices of the corresponding zone, calculate a sensitivity matrix using the received set of local measurements, determine whether a voltage violation has occurred in the corresponding zone, determine a DER set point using the received set of local measurements in response to determining the voltage violation has occurred in the corresponding zone, and transmit the DER set point to the DER.

    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: A method for a building automation system to control a comfort level in a building includes tracking a building occupant's activity data using a wearable activity tracker. A smartphone is coupled to the wearable activity tracker. Activity data is collected from the wearable activity tracker using a smartphone app operating on the building occupant's smartphone, and a comfort value is determined using the smartphone app based on the activity data. A report of the comfort value is transmitted to a building automation system (BAS) app from the smartphone, and the output of a building system is controlled based on the comfort value.
