  • Patent number: 10707050
    Abstract: A glitch monitoring system is disclosed. The glitch monitoring system allows the capture of voltage and current data from one or more channels. Additionally, voltage and current data that occurred prior to the glitch can also be captured for further analysis. The amount of data may be thousands or millions of bytes. Additionally, the description of a glitch, including an upper threshold, a lower threshold and a duration, can be programmed. This allows spurious perturbation in voltage or current to be ignored if desired. Further, the voltage and current data may be filtered if desired prior to being stored in memory. This data can later be retried by a main controller and analyzed to determine a potential cause of the glitch and potential remedial actions.

  • Patent number: 10678984
    Abstract: The available delivery capability (ADC) of a power distribution network with respect to a power transaction is evaluated in real-time. The power transaction involves simultaneous power deliveries from power sources in a source area to loads in a sink area. First, a list of contingencies are ranked in the power distribution network with respect to static security constraints to obtain a subset of top-ranked contingencies. For each top-ranked contingency in the subset, a representation of the power transaction in a steady state of the power distribution network, in a form of parameterized three-phase power flow equations, is solved to obtain a corresponding power delivery capability (PDC) and a corresponding binding constraint among the static security constraints. The reliability of the power transaction in the power distribution network is then evaluated based on, at least in part, a first contingency PDC which is a smallest PDC among obtained corresponding PDCs.

  • Patent number: 10396555
    Abstract: A power metering system includes any number of sites and a central database. Loads within a site are unmetered and a sensor data vector over time includes sensor data, operational data and external data. Iteration occurs over time intervals for all unmetered loads and the unmeasured power for each interval is disaggregated by matching a load type with a computer model in the central database having the same feature domain in order to predict the power usage of each load. Iteration again occurs over those intervals in which only a single load is operating; the power of that load is determined to be the unmeasured power minus miscellaneous power, and a new computer model is fitted for that single load and also uploaded to the database. The feature domain of an existing model may also be increased. Both iteration steps repeat until no more unmeasured power can be disaggregated.

  • Patent number: 9953266
    Abstract: Energy usage can be monitored within at least one building having a plurality of energy consuming components. A database can be generated that contains values for a set of data points corresponding to data received from the plurality of energy consuming components. A change in a configuration can be detected for the plurality of energy consuming components based upon a change in values received from plurality of energy consuming components relative to the database. Based upon the change, an additional data point can be added to the set of data points in the database. Based upon the values for the set of data points, a probability can be determined that a rule for the additional data point is valid. A message can then be generated that includes the determined probability.

  • Patent number: 9699529
    Abstract: Devices state changes in a building may be determined using a combination of power monitoring and network monitoring. Power monitoring may be performed by obtaining a power monitoring signal and processing the power monitoring signal with models to determine information about state changes of one or more devices in the building. Network monitoring may be performed by receiving information about network packets transmitted by devices in the building and processing the information about the network packets to determine information about state changes of one or more devices in the building. For some devices and some implementations, information about state changes of a device may be determined by using both power monitoring and network monitoring.

  • Patent number: 9672577
    Abstract: A method for estimating component power usage using aggregate power usage data are provided in the illustrative embodiments. A power estimation model is received, the model correlating a factor of the component with an aggregate power consumption of a set of components during a period, the component being a member of the set of components, the component being a hardware device operating in the data processing environment and consuming electrical power, the factor being a characteristic of the component related to the consumption of the electrical power in the component. A value of the factor at a determined time is received. The value of the factor is applied to the power estimation model to generate an estimate of electrical power consumed by the component. The estimate is output as the estimated power usage of the component when the factor attains the value.

  • Patent number: 9523718
    Abstract: The invention relates to a disaggregation apparatus for identifying an appliance in an electrical network (2) comprising multiple appliances (3, 4, 5). A voltage meter (7) measures a first change in a mains voltage (V) delivered to the appliances of the electrical network, while an operational state of an appliance is modified, and a second change in the mains voltage, while a switchable load is switched. An appliance determination unit (9) determines the appliance, of which the operational state has been changed, based on the measured first change in the mains voltage, the measured second change in the mains voltage and the resistance of the switchable load. Thus, an appliance can be determined without detecting switching flickers in very short time durations, i.e. high sampling rates and continuous monitoring are not necessarily required. This reduces the technical efforts of the disaggregation apparatus for performing the disaggregation function.

  • Patent number: 9519912
    Abstract: In demand prediction, a history of demand for a resource is modeled to generate a baseline model of the demand, and demand for the resource at a prediction time is predicted by evaluating a regression function of depth k operating on an input data set including at least the demand for the resource at the prediction time output by the baseline model and measured demand for the resource measured at k times prior to the prediction time. The resource may be off-street parking, and the input data set may further include weather data. The regression function may comprise a support vector regression (SVR) function that is trained on the history of demand for the resource. The baseline model suitably comprises a Fourier model of the history of demand for the resource.

  • Patent number: 9506963
    Abstract: Systems and methods are provided for estimating power breakdowns for a set of one or more appliances inside a building by exploiting a small number of power meters and data indicative of binary power states of individual appliances of such set. In one aspect, a breakdown estimation problem is solved within a tree configuration, and utilizing a single power meter and data indicative of binary power states of a plurality of appliances. Based at least in part on such solution, an estimation quality metric is derived. In another aspect, such metric can be exploited in a methodology for optimally placing additional power meters to increase the estimation certainty for individual appliances to a desired or intended level. Estimated power breakdown and energy breakdown—individually or collectively referred to as consumption breakdown—rely on measurements and numerical simulations, and can be evaluated in exemplary electrical network utilizing binary sensors.
