Patent number: 8615330Abstract: A topology structure of a power system is acquired. At least one unification set in the power system is identified based on the topology structure. Devices belonging to the same unification set have the same outage state. The at least one unification set is recorded, so as to concurrently maintain devices belonging to the same unification set. Advantageously, one or more embodiments reduce number of outages caused by power system device maintenance.Type: GrantFiled: October 29, 2010Date of Patent: December 24, 2013Assignee: International Business Machines CorporationInventors: Jin Dong, Feng Jin, Hai Rong Lv, Qi Ming Tian, Wen Jun Yin

Patent number: 8473230Abstract: A system for detecting conflicts between a power supply guarantee request (PSGR) and an outage request (OR) in a power grid. The system comprises: an accompanying outage analysis device for receiving a first outage device set including OR related devices, and using geographic information about devices in the power grid to determine a second outage device set, the second outage device set including devices in the first outage device set and accompanying outage devices that need to be in outage together with the devices in the first outage device set; an outage scale determination device for using topology information about the power grid to determine a power grid outage scale in which all of the devices in the second outage device set can be in outage; and a conflict detection device for receiving a power supply guarantee device set including PSGR related devices, and judging, for each device in the power supply guarantee device set, whether the device is included in the power grid outage scale.Type: GrantFiled: February 10, 2011Date of Patent: June 25, 2013Assignee: International Business Machines CorporationInventors: Jin Dong, Feng Jin, Hai Rong Lv, Qi Ming Tian, Wen Jun Yin

Patent number: 8467983Abstract: A method detects conflicts between a power supply guarantee request (PSGR) and an outage request (OR) in a power grid. The method comprises receiving a first outage device set including OR related devices and a power supply guarantee device set including PSGR related devices. Geographic information about devices in the power grid is used to determine a second outage device set, which includes devices in the first outage device set and accompanying outage devices that need to be in outage together with devices in the first outage device set. Power grid topology information is used to determine a power grid outage scale in which all devices in the second outage device set can be in outage. For each device in the power supply guarantee device set, the method detects whether the device is included in the power grid outage scale, to determine any conflict between the PSGR and OR.Type: GrantFiled: July 3, 2012Date of Patent: June 18, 2013Assignee: International Business Machines CorporationInventors: Jin Dong, Feng Jin, Hai Rong Lv, Qi Ming Tian, Wen Jun Yin

Patent number: 8386298Abstract: A system, method and computer program product for providing the ability for retailers to devise a current channel strategy (e.g., adaptive price setting) that considers competitors in a dynamic competing environment, and that enables computing a competitive advantage of a channel. To estimate a price for selling a product j in a commerce channel comprises: a) receiving, at a processor device, real market data including sales and price history data of a product j sold by one or more retailers over one or alternate sales channels t; generating, by the processor device, a competitive advantage parameter value based on the sales and price history data; and, computing, utilizing the competitive advantage parameter value, an optimum price for a particular product to be marketed in one of the one or alternate sales channel.Type: GrantFiled: August 18, 2010Date of Patent: February 26, 2013Assignee: International Business Machines CorporationInventors: Xin Xin Bai, Jin Dong, Ta-Hsin Li, Hai Rong Lv, Wen Jun Yin, Bin Zhang
