  • Patent number: 9484744
    Abstract: A scheduling apparatus includes a first calculator, a storage, and a second calculator. The first calculator is configured to calculate an assignment of plural time slots to a consumer. Each of the plural time slots is classified into at least any of plural categories. The storage is configured to store a first demand, from the consumer, regarding an extent to which the categories associated with the assignment are biased. The second calculator is configured to calculate an extent to which the categories associated with the assignment calculated by the first calculator are biased and calculate a first evaluation value representing a deviation between the first demand and an extent to which the categories associated with the assignment calculated by the first calculator are biased. The first calculator calculates the assignment so as to optimize an evaluation function including the first evaluation value.

  • Publication number: 20160275222
    Abstract: According to one embodiment, an estimation device includes a first parameter generator, an energy simulator, a cost calculator, and a parameter selector. The first parameter generator determines values of one or more constituents of one or more first parameters to generate the one or more first parameters, the one or more constituents representing an operation status of a facility. The energy simulator calculates estimation information of energy consumption related to the first parameters by simulating energy consumption of the facility based on the first parameters. The cost calculator calculates evaluation values of the first parameters based on the estimation information of the energy consumption of the facility and actual performance information of the energy consumption of the facility. The parameter selector selects one of the plural first parameters based on the evaluation values.

  • Patent number: 9310785
    Abstract: 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.

  • Patent number: 9197067
    Abstract: 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.

  • Patent number: 9134708
    Abstract: An example information processing device includes first and second receiving units, a deciding unit, and first and second transmitting units. The first receiving unit receives adjustment limit information from a plurality of first external devices. The deciding unit determines adjustment rules on the basis of the adjustment limit information. The first transmitting unit transmits the adjustment rules to second and third external devices. The second receiving unit receives determination information from a fourth external device. The second transmitting unit transmits the adjustment rules to the first external devices when integrated schedule information satisfies a condition. When the integrated schedule information does not satisfy the condition, the deciding unit changes the adjustment rules. When the deciding unit has changed the adjustment rules, the first transmitting unit transmits new adjustment rules to the second and third external devices.

  • Patent number: 8571720
    Abstract: 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.
