Patent number: 11120193Abstract: A computer-implemented method includes identifying a noise cluster, representing the noise cluster according to a variational model, projecting the variational model onto one or more corners to yield a projected noise cluster, and determining a computed noise for the projected noise cluster. Optionally, the noise cluster includes one or more noise cluster elements, and each of the noise cluster elements are expressed as one or more circuit element terms, according to a canonical form. Optionally, at least one of the corners is a bounding corner. For the bounding corner, the projected noise cluster is generated by maximizing the circuit element terms for those noise cluster elements that tend to increase noise, and by minimizing the circuit element terms for those noise cluster elements that tend to decrease noise, whereby noise is maximized for the canonical form. A corresponding computer program product and computer system are also disclosed.Type: GrantFiled: July 22, 2019Date of Patent: September 14, 2021Assignee: International Business Machines CorporationInventors: Steven J.

Patent number: 10521525Abstract: Embodiments herein relate to improving a stochastic forecast for uncertain power generations and demands to quantify an effect on an electrical power grid. To improve the stochastic forecast, a method includes fitting marginal distributions to data of the uncertain power generation and demand by power generation and demand nodes of the electrical power grid. The power generation and demand nodes provide corresponding uncertain power generation and demand based on a renewable energy source. The method also includes determining a correlation structure between the power generation and demand nodes by transforming the data from marginal distributions to a second distribution and by fitting a multivariate time series on transformed data. The method also includes simulating multivariate stochastic forecast with an improved correlation structure.Type: GrantFiled: January 23, 2017Date of Patent: December 31, 2019Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Aanchal Goyal, Fook-Luen Heng, Younghun Kim, Tarun Kumar, Mark A.
