Patent number: 10015184Abstract: Systems and methods of detecting an attack in a utility grid are described. An anomaly detector identifies a first indication of signal samples used by a controller to adjust a voltage level at a load terminal during a first time interval, and a first indication of voltage levels at the load terminal of the controller. The anomaly detector identifies a regulator emulation model (“REM”) for the controller. The anomaly detector receives a second indication of signal samples used by the controller during a second time interval, and a second indication of a voltage level at the load terminal. The anomaly detector detects a level of conformance with the REM based on a comparison of the second indication of the voltage levels with a voltage level determined by inputting the second indication of the signal samples into the REM. The anomaly detector provides a notification indicating an anomaly with the controller.Type: GrantFiled: September 6, 2017Date of Patent: July 3, 2018Assignee: UTILIDATA, INC.Inventor: David Gordon Bell

Patent number: 9702730Abstract: This disclosure is directed to a system and method of allocating energy provided by a power source. The system includes a computing device that receives, from meters, observations of energy delivered by the power source to sites. The device classifies the sites into consumption classes, where a first consumption class has complete coverage and a second consumption class has incomplete coverage. The device determines a metric for a characteristic of energy for the first class. The device determines a first demand for the first class based on the metric for the characteristic of energy for the first class. The device generates a sampling distribution of the metric for the characteristic for the second class and determines a second demand for the second class based on the sampling distribution. The device determines a dissipation metric based on the first and second demands.Type: GrantFiled: August 7, 2014Date of Patent: July 11, 2017Assignee: UTILIDATA, INC.Inventor: David Gordon Bell

Publication number: 20170093160Abstract: The present disclosure is directed to systems and methods of managing power delivery in a utility grid. A controller receives, from one or more metering devices, samples of characteristics of electricity delivered from a power source to one or more consumer sites. The controller generates weights for the samples of characteristics of electricity to compensate for void samples at the controller. The controller determines one or more parameters using the weights applied to the samples of characteristics of electricity. The controller determines a secondary voltage drop based on the one or more parameters. The controller adjusts, based on the determined secondary voltage drop, a primary voltage setpoint used to establish a voltage level provided to the distribution transformer by a regulating transformer located at the primary distribution level.Type: ApplicationFiled: September 23, 2016Publication date: March 30, 2017Inventor: David Gordon Bell

Publication number: 20160366170Abstract: Systems and methods of detecting an attack in a utility grid are described. An anomaly detector establishes a first metric generated using signals received from at least one of one or more controllers of the utility grid or one or more metering devices of the utility grid. The first metric identifies nominal behavior of control or consumption in the utility grid absent anomalies. The anomaly detector monitors signals received from the controllers or the metering devices. The anomaly detector determines, using the monitored signals, a second metric identifying current behavior of at least one of control or consumption in the utility grid. The anomaly detector compares the first metric with the second metric to detect an anomaly in control or consumption in the utility grid. The anomaly is attributable to an attack on a controller or a metering device. The anomaly detector provides an alert indicating the detected anomaly.Type: ApplicationFiled: February 8, 2016Publication date: December 15, 2016Inventor: David Gordon Bell

Publication number: 20160268811Abstract: The present disclosure is directed to determining a secondary voltage drop in a utility grid. A controller receives characteristics of electricity delivered from a power source to one or more consumer sites during a first time interval and a second time interval prior to the first time interval. The controller determines a secondary voltage drop based on the characteristics of electricity delivered during the first interval and the characteristics of electricity delivered during the second time interval. The secondary voltage drop corresponding to a distribution transformer located between a primary distribution level of the utility grid and a secondary distribution level of the utility grid corresponding to the one or more consumer sites. The controller establishes, based on the determined secondary voltage drop, a voltage setpoint to adjust a voltage level provided to the distribution transformer by a regulating transformer located at the primary distribution level.Type: ApplicationFiled: March 9, 2016Publication date: September 15, 2016Inventor: David Gordon Bell

Patent number: 9391459Abstract: A mesh delivery system for controlling electricity supplied to one or more electrical devices from a power source are disclosed. Signals relating to characteristics of the electrical devices are uniformly or non-uniformly sampled at discrete intervals are provided along with associated sampling time indications via the mesh network to a destination controller. The controller applies a compacting algorithm to the received samples and the received associated time indications to generate a paired vector comprising samples and an associated compacted time indication. The paired vector representing the sampled signal in a time domain is transformed into a discrete Fourier spectrum of the signal in the frequency domain where the discrete Fourier spectrum of the signal is in a uniformly sampled in the frequency domain.Type: GrantFiled: March 14, 2014Date of Patent: July 12, 2016Assignee: UTILIDATA, INC.Inventor: David Gordon Bell

Patent number: 9143076Abstract: A system and process includes continuously determining an applied armature voltage supplied to a polyphase synchronous machine for which a maximum mechanical load is characterized by a pull-out torque. The armature voltage is supplied from a power source via one of many taps of a regulating transformer. The armature voltage being supplied from the power source to the machine is changed by selecting one of the voltage levels from the taps of the regulating transformer. The tap voltage levels are selected based on the determined applied armature voltage to minimize power consumption of the machine while ensuring based on a predetermined confidence level that the pullout torque of the machine will not be exceeded.Type: GrantFiled: December 23, 2013Date of Patent: September 22, 2015Assignee: UTILIDATA, INC.Inventor: David Gordon Bell
