Patent number: 10816942Abstract: A predictive-control approach allows an electricity provider to monitor and proactively manage peak and off-peak residential intra-day electricity usage in an emerging smart energy grid using time-dependent dynamic pricing incentives. The daily load is modeled as time-shifted, but cost-differentiated and substitutable, copies of the continuously-consumed electricity resource, and a consumer-choice prediction model is constructed to forecast the corresponding intra-day shares of total daily load according to this model. This is embedded within an optimization framework for managing the daily electricity usage. A series of transformations are employed, including the reformulation-linearization technique (RLT) to obtain a Mixed-Integer Programming (MIP) model representation of the resulting nonlinear optimization problem. In addition, various regulatory and pricing constraints are incorporated in conjunction with the specified profit and capacity utilization objectives.Type: GrantFiled: November 15, 2016Date of Patent: October 27, 2020Assignee: International Business Machines CorporationInventors: Soumyadip Ghosh, Jonathan R.

Patent number: 10282795Abstract: A streams platform is used. Multiple streams of electricity usage data are received, each from an electrical meter providing periodic updates to electrical usage for devices connected to the electrical meter. Weather information is received corresponding to locations where the electrical meters are. Real-time predictive modeling of electricity demand is performed based on the received multiple streams of electricity usage data and the received weather information, at least by performing: updating a state space model for electrical load curves using the usage data from the streams and the weather, wherein the updating uses current load observations for the multiple streams for a current time period; and creating forecast(s) for the electricity demand. The forecast(s) of the electricity demand are output. Appliance-level predictions may be made and used, and substitution effects and load management functions may be performed.Type: GrantFiled: June 22, 2016Date of Patent: May 7, 2019Assignee: International Business Machines CorporationInventors: Soumyadip Ghosh, Jonathan R.

Patent number: 8204773Abstract: A method and system for forecasting demand for order configurations are provided. The method and system, in one aspect, expresses attach rates within a family of n options as a set of n positive numbers that sum to 1. By applying suitable transformations to the attach rates, they are modeled as a random vector in (n?1)-dimensional Euclidean space. The distribution of the transformed attach rates are modeled as a distribution family specified by a location vector and a dispersion matrix. The dispersion matrix is simplified, for example, using historical data or expert judgment or both to identify option families that have dependent demand. Simplifying may also include expressing dependence between options by a simple model that involves few parameters. Location vector is estimated by computing point forecasts of transformed attach rates. The parameters of the dispersion matrix are estimated by calibration on historical data, using the dispersion of the errors in historical point forecasts.Type: GrantFiled: December 4, 2007Date of Patent: June 19, 2012Assignee: International Business Machines CorporationInventor: Jonathan R.

Patent number: 8175830Abstract: A method and system for estimating a magnitude of extremely rare events upon receiving a complete data sample and a specific exceedance probability are described. A distribution is chosen for a complete data sample. An optimal subsample fitted to the distribution is obtained. The optimal subsample is a largest acceptable subsample. A subsample is considered as an acceptable subsample when a goodness-of-fit test on the subsample is satisfactory (i.e., higher than a predetermined threshold). In addition, if a tail measure of an acceptable subsample lies outside a confidence interval of any smaller acceptable subsample, the acceptable subsample is considered as an unacceptable. Based on the optimal subsample and an inputted exceedance probability, a quantile estimate is computed, e.g., by executing an inverse of a cumulative distribution function of generalized Pareto distribution.Type: GrantFiled: October 31, 2008Date of Patent: May 8, 2012Assignee: International Business Machines CorporationInventor: Jonathan R.

Patent number: 7020593Abstract: A new method is used to model the class probability from data that is based on a novel multiplicative adjustment of the class probability by a plurality of items of evidence induced from training data. The optimal adjustment factors from each item of evidence can be determined by several techniques, a preferred embodiment thereof being the method of maximum likelihood. The evidence induced from the data can be any function of the feature variables, the simplest of which are the individual feature variables themselves. The adjustment factor of an item of evidence Ej is given by the ratio of the conditional probability P(C|Ej) of the class C given Ej to the prior class probability P(C), exponentiated by a parameter aj. The method provides a new and useful way to aggregate probabilistic evidence so that the final model output exhibits a low error rate for classification, and also gives a superior lift curve when distinguishing between any one class and the remaining classes.Type: GrantFiled: December 4, 2002Date of Patent: March 28, 2006Assignee: International Business Machines CorporationInventors: Se June Hong, Jonathan R.
