Patent number: 11637756Abstract: This document describes systems and techniques for evaluating and improving distribution-grid data transportability. These systems and techniques allow engineers to quantify the data transportability of a communication system within or connected to a distribution grid, which represents an ability to transport in real-time telemetry from source locations (e.g., sensors in the distribution grid) to control mechanisms. Distribution engineers can use the sensor readings to perform grid analytics, control operating parameters, and operate protection systems. Distribution engineers can also use the transportability of the communication system to evaluate the observability of the distribution grid, which represents an ability to combine actual measurements and various types of computations (e.g., analytics, estimators, forecasters) from a system model.Type: GrantFiled: June 4, 2021Date of Patent: April 25, 2023Assignee: Battelle Memorial InstituteInventors: Jeffrey D.

Patent number: 11313889Abstract: This document describes systems and techniques for evaluating and improving distribution-grid observability. These systems and techniques allow engineers to quantify the observability of a distribution grid, which represents an ability to combine actual measurements and various types of computations (e.g., analytics, estimators, forecasters), from a system model. Distribution engineers can also identify islands of observability where operating parameters, including voltages, currents, and power flows, can be determined from available sensor readings. By exclusion, distribution engineers can similarly identify areas of the distribution grid with observability deficiencies that may require additional instrumentation to maintain proper operation. Distribution engineers, using an iterative or automated process, can determine the observability of the system model with new or relocated sensors to generate a sensor allocation plan.Type: GrantFiled: June 12, 2020Date of Patent: April 26, 2022Assignee: Battelle Memorial InstituteInventors: Andrew P.

Patent number: 9450454Abstract: In one embodiment, a grid application function is hosted at a primary grid device in a utility grid, which may determine whether or not to distribute at least a portion of the grid application function to one or more distributed secondary grid devices in the utility grid. In general, the one or more distributed secondary grid devices will be associated with a subset of the utility grid that is associated with the primary grid device (e.g., a sub-grid). Once a determination has been made, the primary grid device may dynamically distribute the grid application function, or a portion thereof, to the distributed secondary devices according to the determination. In addition, in another embodiment, the grid application function may also be withdrawn, such as from a particular secondary grid device or else from the primary grid device to an originating grid device.Type: GrantFiled: May 30, 2012Date of Patent: September 20, 2016Assignee: Cisco Technology, Inc.Inventor: Jeffrey D.

Patent number: 8893216Abstract: Security is enabled in an electrical system by examining a configuration file for a substation present in the electrical system, where the substation includes one or more electrical devices and one or more network devices. Based on the examination of the configuration file, information is determined on a characteristic of an electrical device that is selected from a group including a type, allowed role of the electrical device and allowed communication modes for the electrical device. Based on the determined information, a basis for controlling the role and communication modes for the electrical device is identified. A security policy is configured in a network device in the substation to incorporate the identified basis. Based on the configured security policy in the network device, communication patterns for the electrical device are allowed that are associated with the allowed role and allowed communication modes for the electrical device.Type: GrantFiled: June 15, 2011Date of Patent: November 18, 2014Assignee: Cisco Technology, Inc.Inventors: Navindra Yadav, Jeffrey D.
