Abstract:
A power management apparatus manages power consumptions of a plurality of equipments provided in a facility. The power management apparatus comprises: an acquisition unit configured to acquire power amount information which is information related to power consumption of the plurality of equipments; and a controller configured to calculate, based on the power amount information, a predicted value of a power consumption amount which is an accumulated value of power consumptions of the plurality of equipments in a predetermined time period. The plurality of equipments includes an automatically-controlled equipment to which automatic control of automatically controlling power consumptions by the controller is applicable, and a non-automatically-controlled equipment to which the automatic control is not applied. The controller notifies a user of information for identifying the non-automatically-controlled equipment from among the plurality of equipments, in a case in which the predicted value exceeds a threshold value.
Abstract:
A radio communication system 1 includes a pico-cell base station PeNB installed in a communication area of a macro-cell base station MeNB, having lower transmission power than the macro-cell base station MeNB, and expanded in its coverage. The macro-cell base station MeNB determines a degree of expanding the coverage of the pico-cell base station PeNB, according to an amount of usable PDSCH resources of the macro-cell base station MeNB.
Abstract:
A radio communication system (1) includes a pico-cell base station (PeNB) which is located in the communication area of a macro-cell base station (MeNB) and the transmission power of which is lower than that of the macro-cell base station (MeNB). For radio resources that can be used as PDSCH, a resource division ratio that is a ratio between unusable PDSCH resources, which cannot be used by the macro-cell base station (MeNB), and usable PDSCH resources, which can be used by the macro-cell base station (MeNB), is decided, and a radio resource is allocated, out of the usable PDSCH resources defined in accordance with the decided resource division ratio, to a radio terminal that is to connect to the macro-cell base station (MeNB). The resource division ratio is decided based on the traffic load of each base station.
Abstract:
An EMS (30) is equipped with a control unit (31) for obtaining a first measurement value which indicates an operating state of an apparatus (11) at a predetermined time point and at least one second measurement value which indicates an operating state of the apparatus (11) at a time point earlier than the predetermined time point. The control unit (31) calculates a first reference value, which indicates a reference for the operating state of the apparatus (11), by using the second measurement value and determines the presence/absence of an anomaly of the apparatus (11) on the basis of a comparison result between the first measurement value and the first reference value.
Abstract:
A power management system 1 is provided with an HEMS 500 connected to an SOFC unit 100 and a load 400. The power management system comprises: a reception unit 510 that acquires power consumption of the load; and a transmission unit 520 that notifies the SOFC unit 100 of pseudo power consumption that is obtained by adding a predetermined offset to the power consumption acquired by the a reception unit 510. The SOFC unit 100 controls power output from the SOFC unit 100 to follow the pseudo power consumption.

Abstract:
A management method includes a step A of estimating, for each of the plurality of entities, an error pattern related to a prediction error occurring when a power consumption amount in a future period is predicted; and a step B of determining a group of entities from among the plurality of entities based on the error pattern, wherein the group is a destination of a power reduction request for reducing the power consumption amount. The step A includes a step of estimating whether the prediction error is a positive error or a negative error. The step B includes a step of determining the group such that a total prediction error of the group is minimized, by combining an entity of which the prediction error is estimated to be a positive error and an entity of which the prediction error is estimated to be a negative error.
Abstract:
Provided are a power control system, power control device, server device, and method for controlling a power control system in which the power control device can control load devices even when communication between the power control device and the server device is cut off, and which allow for timely discovery that communication has been cut off. A server device (20) extracts at least one of an elapsed time and remaining number of control instructions not acquired by a power control device (10) by polling and provides a warning when at least one of the elapsed time and the remaining number is at least a predetermined value. When the server device does not respond to polling, the power control device (10) creates a control instruction based on control guideline information and executes the control instruction.
Abstract:
A power control device, power control method, and power control system can suppress an increase in the processing load on the server when simultaneously controlling load devices belonging to power control devices and can suppress an increase in communication traffic between the server and the power control device. Provided are a storage unit (101) storing control instruction effect information including control instructions for load devices possessed by a consumer's facility and a predicted power reduction amount for each of the control instructions, an instruction acquisition unit (102) that acquires a power reduction instruction from a server (20), a control instruction creation unit (103) that creates a combination of control instructions that satisfies the power reduction instruction based on the predicted power reduction amount included in the control instruction effect information, and a control unit (104) that executes the control instructions in the combination.
Abstract:
A HEMS (100) for controlling equipment connected to an in-house network (3), via the in-house network (3), monitors the in-house network (3). The HEMS (100) which, when detecting that new equipment is connected to the in-house network (3), causes the first communication unit to inquire the new equipment as to information related to the new equipment.
