Publication number: 20160018458Abstract: Methods and arrangements for localizing an outage in a power grid. An outage is detected in a power grid, the power grid comprising interconnected nodes. At least one candidate network topology (in the power grid) with respect to the outage is determined, and power consumption information and measured voltages relative to the nodes in the power grid are received. Voltage at a plurality of the nodes in the power grid is estimated based on the received power consumption information and on the at least one candidate network topology, and a location of the outage is estimated, based on the estimated node voltages and measured voltages. Other variants and embodiments are broadly contemplated herein.Type: ApplicationFiled: July 16, 2014Publication date: January 21, 2016Inventors: Chumki Basu, Kaushik Das, Ulrich A. Finkler, Jagabondhu Hazra, Ashok Pon Kumar, Devasenapathi Periagraharam Seetharamakrishnan, Amith Singhee

Publication number: 20150349529Abstract: Methods, systems, and computer program products for distributed phase balancing are provided herein. A method of use in connection with a distribution network having a phase imbalance includes determining one or more power consumption parameters associated with a given entity of the distribution network; determining one or more power supply parameters associated with the given entity of the distribution network; and computing, based on said one or more power consumption parameters and said one or more power supply parameters, at least one of (i) a level of power consumption increase and/or decrease and (ii) a level of power supply increase and/or decrease associated with one or more devices of the given entity to remedy the phase imbalance within the distribution network.Type: ApplicationFiled: May 27, 2014Publication date: December 3, 2015Applicant: International Business Machines CorporationInventors: Vijay Arya, Tanuja H. Ganu, Jagabondhu Hazra, Saiful Azmi bin Hj Husain, Shivkumar Kalyanaraman, Devasenapathi P. Seetharamakrish

Patent number: 9188967Abstract: Methods and arrangements for enforcing demand management in electrical grids. Electrical power is provided from an electrical network to at least one substation, the electrical network including an electrical generation grid in communication with the at least one substation, the at least one substation comprising a power limiter. Electrical power is provided from the at least one substation to a plurality of locations, each location comprising a smart power demand manager which controls electrical power delivery to at least power-drawing item. There is detected, with respect to the electrical network, at least one discrepancy comprising at least one of: an unbalanced network load; an unscheduled network load; a change in network supply; and a change in network condition. In response to such detection, electrical power delivery is controlled via employing the power limiter of the at least one substation in collaboration with at least one smart power demand manager.Type: GrantFiled: October 23, 2012Date of Patent: November 17, 2015Assignees: International Business Machines Corporation, Universiti Brunei DarussalamInventors: Jagabondhu Hazra, Saiful A. Husain, Shivkumar Kalyanaraman, Balakrishnan Narayanaswamy

Publication number: 20150149396Abstract: Embodiments of the present invention provide a system, method, and computer program product to detect and localize non-technical losses in an energy distribution system. A computing device determines the energy consumption of a link and/or node that is associated with an energy grid. The computing device determines the mismatch between the determined energy consumption of the link and/or node and the predicted energy consumption of the link and/or node. The computing device also determines the location of unauthorized energy consumption within the energy that is associated with the mismatch.Type: ApplicationFiled: November 22, 2013Publication date: May 28, 2015Applicant: International Business Machines CorporationInventors: Vijay Arya, Kaushik Das, Jagabondhu Hazra, Shivkumar Kalyanaraman, Balakrishnan Narayanaswamy, Devasenapathi P.

Publication number: 20150066435Abstract: Systems and methods for cognitive alarm management in a power grid are described. In one embodiment, sensor measurements are transformed to determine the state of a power grid. Given current state information relating to the power grid, various analyses of the alarms may be conducted to produce various rankings of the alarms (e.g., by severity, graph analyses, etc.). In an embodiment, using power flow analysis, an optimal ranking is identified from the rankings in which a causal alarm is prioritized for resolution. Given the resolution of the causal alarm, remaining alarms (either all or a sub-set) may be resolved without further action. Thus, an embodiment provides an appropriate ranking of alarm conditions in a power grid such that the optimal resolution of alarms may be achieved. Other variants and embodiments are broadly contemplated herein.Type: ApplicationFiled: August 30, 2013Publication date: March 5, 2015Applicant: International Business Machines CorporationInventors: Chumki Basu, Kaushik Das, Jagabondhu Hazra, Devasenapathi P.
