A degradation estimation method includes: a service record acquiring step acquiring a service record of maintenance of a device; an analysis step analyzing a degradation state of the device from the service record; a determination standard adjustment step adjusting a first determination standard to a second determination standard depending on the analyzed degradation state, the first determination standard being determined in advance for estimating whether there is degradation of the device or not; a device data acquisition step acquiring first device data indicating state of the device; and a first degradation estimation step estimating whether there is degradation of the device or not using the acquired first device data and the second determination standard.

Degradation estimation method and degradation estimation apparatus

A method for controlling an information terminal, including: (a) causing a display of the information terminal to display a first screen that includes a message recommending an action that leads to a reduction in a power consumption amount of a facility; and (b) causing the display to display a second screen that prompts an operator to execute an input operation for adjusting the frequency at which (a) is executed, in which, when the input operation is executed, (a) is executed at the frequency adjusted according to the input operation.

Method for controlling information terminal, and information system

An information terminal control method includes: (a) predicting whether an amount of power consumption in a shop exceeds a target value; (b) when the amount of power consumption in the shop is predicted to exceed the target value, causing a display of an information terminal to display a screen displaying a time period during which the amount of power consumption in the shop is predicted to exceed the target value; and (c) causing the display to display a screen displaying a message that presents an action to reduce the amount of power consumption in the time period.

Information terminal control method and energy conservation support system

An apparatus state estimation method includes: storing first apparatus data that indicates a state of an apparatus; storing a work record, the work record being a record indicating a work that has been carried out for maintenance of the apparatus; estimating a category that is a malfunction of the apparatus or a content of a measure by using the work record; and learning a relationship between the estimated category and the first apparatus data.

Apparatus state estimation method, apparatus state estimation device, and data providing device

A power supply and demand control method for a power storage system includes predicting a consumption power of a customer for each of time slots divided by a specific time interval, assigning one of a frequency control or a peak shaving control to each of the time slots based on the predicted consumption power, controlling the storage battery based on the assigned frequency control or the assigned peak shaving control in each of the time slots, wherein the peak shaving control is assigned to each of the time slots in which the predicted consumption power is higher than a contract power, and the frequency control is assigned to each of the times slot in which the predicted consumption power is equal to or lower than the contract power.

Power supply and demand control method, power supply and demand control device

An electric power control method for an electric power load and an electric power storage device including assigning one of a peak shaving control or other services to at least one of time slots that are divided by a specific time unit, obtaining a consumption power of the electric power load of each of the time slots, determining power-purchase electric power according to the consumption power of each of the time slots, restricting a consumption power of the electric power load at one or more peak slots where the consumption power of the electric power load is more than or equal to a target power-purchase electric power upper limit, restricting the restricted consumption power of the electric power load and discharging the electric power storage device at one or more peak slots if the restricted consumption power of the electric power load is more than or equal to a target power-purchase electric power upper limit and the peak shaving is assigned.

Electric power control method and electric power control device

A method of controlling frequency of a power system by a frequency control system includes: obtaining a frequency control command to keep frequency fluctuation of the power system within a predetermined range; obtaining information on electric power to be received or supplied by m second apparatuses, and determining n first command values for controlling electric power to be received or supplied by n first apparatuses, based on the frequency control command obtained in the obtaining of a frequency control command and the obtained information on electric power to be received or supplied by the m second apparatuses; and transmitting each of the n first command values determined in the determining to a corresponding one of the first apparatuses.
