Patent number: 9310785Abstract: According to one embodiment, an apparatus sends a request to adjust a power consumption to a plurality of request targets, based on power supply and demand. A minimum adjustment time of each request target is stored. The minimum adjustment time is an interval between a time when a request target receives the request and a time when the request target starts to adjust the power consumption. If an estimation value of the power supply is different from an estimation value of the power demand at a first time to start to adjust, at least one request target is selected from the request targets by using the minimum adjustment time. The at least one request target is acceptable for the request at a second time as a predetermined time prior to the first time. A first adjustment amount to the at least one request target is calculated until the second time.Type: GrantFiled: July 17, 2013Date of Patent: April 12, 2016Assignee: Kabushiki Kaisha ToshibaInventors: Tomoshi Otsuki, Hisashi Hayashi

Patent number: 9197067Abstract: An electric power supply-and-demand control system includes a memory unit, an estimation unit, a first calculation unit, and a second calculation unit. The system is capable of transmitting/receiving data to/from a power management apparatus provided to each of consumers to instruct a power management apparatus to adjust electric power. The memory unit memorizes a supply, consumptions, reserve power, and response results. The estimation unit estimates a response speed on the basis of the response results. The first calculation unit calculates a target value which allows it to eliminate an unbalance between the supply and a demand. The demand is given as a total of the consumptions. The second calculation unit calculates second adjustment amounts so that a total of the second adjustment amounts approaches the target value and is in the range.Type: GrantFiled: June 5, 2012Date of Patent: November 24, 2015Assignee: Kabushiki Kaisha ToshibaInventors: Tomoshi Otsuki, Yoshiyuki Sakamaki

Patent number: 8571720Abstract: A first predicting unit predicts a power demand required by each customer. A first reliability value calculator calculates the reliability value of the predictive power demand for each customer. Predicted power supply from a power system is calculated with respect to each power generating unit. A second reliability value calculator calculates the reliability value of the predictive power supply for each power generating unit. A balancing unit obtains a supply-demand margin level based on the difference between: a first weighted sum obtained by performing weighted sum on the predictive power demand and a weight depending on the reliability value; and a second weighted sum obtained by performing weighted sum on the predictive power supply and a weight depending on the reliability value. A plan creator creates a plan for controlling power used by the controllable appliance of the customer based on the supply-demand margin level.Type: GrantFiled: March 24, 2011Date of Patent: October 29, 2013Assignee: Kabushiki Kaisha ToshibaInventors: Minoru Yonezawa, Tomoshi Otsuki, Yoshiyuki Sakamaki, Nobutaka Nishimura
