Patent number: 10643163Abstract: A schedule determination device includes an acquisitor, a setter, and a determiner. The acquisitor acquires indexes of an operation schedule of a device and constraint conditions of the indexes. The setter sets a second range, which is narrower than a first range set in the operation schedule before a change, as a range for values of variables that establish constraint conditions of indexes of a new operation schedule. The determiner determines the operation schedule of the device, using the variable values within the second range.Type: GrantFiled: September 12, 2016Date of Patent: May 5, 2020Assignee: Kabushiki Kaisha ToshibaInventors: Masaaki Saito, Dai Murayama, Yutaka Iino, Nagako Hisada

Patent number: 10437273Abstract: A device operation setting apparatus includes a calculator and a determiner. The calculator calculates, based at least in part on a relationship between a setting value regarding operation control of a device and a consumed power of a device, a target value of the consumed power of the device. The determiner determines the setting value to cause that a difference between an actually measured consumed power of the device and the target value of the consumed power of the device calculated by the calculator is within a prescribed range.Type: GrantFiled: September 12, 2016Date of Patent: October 8, 2019Assignee: Kabushiki Kaisha ToshibaInventors: Dai Murayama, Masaaki Saito, Nagako Hisada, Yutaka Iino

Patent number: 10054971Abstract: A received electric power reduction information calculation apparatus (corresponding to an example of a received energy reduction information calculation apparatus) has an energy predictor and a reduction information calculator. The energy predictor predicts a prediction amount of at least one of energy supply and energy consumption in a future prescribed time period with respect to at least one of an energy-supplying equipment and an energy-consuming equipment, based on a request for reduction of the received energy. The reduction information calculator calculates the reduction amount of the received energy associated with the prediction amount, based on an energy fee reflected from an expected fee of incentive with respect to the reduction request of the received energy.Type: GrantFiled: June 9, 2014Date of Patent: August 21, 2018Assignee: Kabushiki Kaisha ToshibaInventors: Masaaki Saito, Dai Murayama, Yutaka Iino, Nagako Hisada

Patent number: 9991720Abstract: A load control apparatus and a load control system capable of more efficiently using power generated from a private power generator, in which a load control apparatus includes a memory, a selector, and a load controller. The memory is configured to store a plurality of patterns having a plurality of control operations that are prioritized for a plurality of loads operated by consuming electric power. The selector is configured to select one of the patterns stored in the memory. The load controller is configured to operate the loads in order of priority on the basis of the control operation of the selected pattern while a total sum of power consumed by the loads does not exceed a target power value representing a value based on power suppliable by the electric generator.Type: GrantFiled: November 10, 2014Date of Patent: June 5, 2018Assignee: Kabushiki Kaisha ToshibaInventors: Nagako Hisada, Koichi Shimozato, Takao Nosaka, Kenichi Yamazaki, Saori Machida, Koji Kimura, Ikuro Komamura, Tomohiro Asazuma

Patent number: 9946242Abstract: An optimized operation schedule of a control-target apparatus is ensured while maximally reducing a burden share to a facility operator. An energy predictor sets, for a control-target apparatus, a predicted value of energy consumption or energy supply within a predetermined future time period based on process data. A schedule optimizer optimizes an operation schedule of the control-target apparatus within the predetermined time period with a predetermined evaluation barometer based on the predicted value, the characteristic of the control-target apparatus, and the process data. An approval request determiner determines a necessity of an approval for a latest operation schedule based on a preset determining condition. A determination result transmitter transmits a determination result by the approval request determiner.Type: GrantFiled: May 27, 2014Date of Patent: April 17, 2018Assignee: Kabushiki Kaisha ToshibaInventors: Masaaki Saito, Dai Murayama, Yutaka Iino, Nagako Hisada

Patent number: 9559549Abstract: According to an embodiment, management server includes estimator, scheduler, acquisition unit, monitoring unit, receiver and setting unit. Estimator calculates estimated value of energy demand in building with electric appliance. Scheduler creates schedule of appliance based on estimated value. Acquisition unit acquires actual value of energy demand. Monitoring unit monitors error between estimated value and actual value. Receiver receives DR signal containing information which prompts suppression of energy consumption in a designated period. Setting unit sets threshold. Estimator recalculates estimated value if error is equal or more than threshold. Scheduler reforms schedule based on the recalculated estimated value.Type: GrantFiled: July 31, 2014Date of Patent: January 31, 2017Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Dai Murayama, Masaaki Saito, Nagako Hisada, Yutaka Iino

Patent number: 9543775Abstract: A battery controller has a holder, a calculator, an acquirer, a calculator, and a controller. The holder holds, at a predetermined time, a value of a received power supplied from an electrical power receiving system to equipment supplied with power from a rechargeable battery. A calculator calculates a difference between a present value of the received power and a last-held value of the received power last-held by the holder at the predetermined time. An acquirer acquires a command value of the received power for each predetermined time period defined by a predetermined time interval. A calculator calculates a limit value of the received power for each time that is shorter than the predetermined time, based on the command value of the received power for each predetermined time period. A controller controls charge and discharge in the rechargeable battery, based on the calculated difference and on the limit value.Type: GrantFiled: June 26, 2014Date of Patent: January 10, 2017Assignee: Kabushiki Kaisha ToshibaInventors: Dai Murayama, Masaaki Saito, Nagako Hisada, Yutaka Iino
