    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: 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 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.
