  • Publication number: 20240129339
    Abstract: Disclosed herein are systems, devices, and methods for improving cybersecurity in electric power systems. In one embodiment, a local controller configured for use in an electric power system may include a measurement subsystem to receive a plurality of conditions related to electrical conditions in a microgrid. A communication subsystem may communicate a set of data related to conditions in the microgrid to a remote controller; and receive a plurality of requests for control actions from the remote controller. An analysis subsystem may generate an assessment of the plurality of requests for control actions in relation to the plurality of conditions related to electrical conditions in the microgrid and identify a subset of the plurality of requests for control actions from the remote controller for execution based on the assessment. A control action subsystem may then issue a control action to an asset in the microgrid.

  • Patent number: 6825766
    Abstract: A radio frequency identification (RFID) capture system for identifying and recording information parameters associated with cargo items. A choke point portal defines a doorway through which passes a plurality of the cargo items in transit from a first location to a second location. The portal includes a radio frequency scanner and a plurality of antennas mounted at specified locations along said portal and in operative communication with said scanner for issuing a radio frequency signal scan across a three dimensional space preceding the portal doorway. A plurality of radio frequency sensitive labels are affixed to selected cargo items. A processor based operating system is in interfacing communication with the portal scanner. In response to each of the labels signaling a selected portal antenna and processor, the processor system captures the information from scanner and, upon comparing the information with an inventory manifest held in a computer readable medium, records the transport of the cargo item.
