no. 1 Embodiment approach

[0097] Hereinafter, a first embodiment of the present invention (hereinafter referred to as the first embodiment) of the present invention will be described with reference to the drawings.

[0098] In the first embodiment, different from the conventional one, in order to predict the power consumption of the load equipment as a whole within a certain predetermined time limit (unit period such as 30 minutes), the operating state of the main load equipment and the overall load equipment at that time are used. It is an information table for saving history related to power consumption and current time information. The main load equipment refers to a part of the load equipment related to the electric power system, such as a display cabinet or an air conditioner that consumes a large amount of power. If the estimated power consumption exceeds the usable power within the remaining time limit, the power consumption can be reduced by controlling, for example, stopping the outdoor unit o...

no. 2 Embodiment approach

[0148] Hereinafter, a second embodiment of the present invention (hereinafter referred to as the second embodiment) of the present invention will be described with reference to the drawings.

[0149] The connection structure of the request control device and the load equipment related to the second embodiment is basically the same as figure 2 The connection configurations of the request control device and the load equipment shown in the first embodiment are the same. Therefore, the connection configuration of the request control device and the load equipment related to the second embodiment is omitted, and the description of the same parts as those in the first embodiment is omitted in the description of the load equipment.

[0150] In the request control device according to Embodiment 2, the store controller 12 performs request control within a set time limit (given time limit: for example 30 minutes) for each given prediction cycle (for example, every 30 seconds). Predict ...

no. 3 Embodiment approach

[0283] Hereinafter, a third embodiment of the present invention (hereinafter referred to as the present embodiment 3) will be described with reference to the drawings.

[0284] The connection structure of the request control device and the load device in the third embodiment is basically the same as figure 2 The connection configurations of the request control device and the load equipment shown in the first embodiment are the same. Therefore, in the description of the connection configuration of the request control device and the load equipment and the load equipment in the third embodiment, the description of the parts common to the first embodiment will be omitted. In addition, the learning processing, prediction processing, and request control processing related to the third embodiment are basically the same as the processing described in the second embodiment. Therefore, the description of the parts in common with the second embodiment among the above three types of pro...

Abstract

A history record of, for example, the relationship between the operation state of a main load appliance and the amount of electric power consumed at that time is stored in an information table, and later, when the amount of electric power expected to be consumed is predicted, by using that information table, it is predicted with high accuracy. Specifically, the history position corresponding to the operation state of the load appliance at the current moment is identified in the information table, and, by adding the amount of electric power actually consumed as stored in the information table thereafter, the predicted amount of electric power expected to be consumed is calculated.

Description

technical field [0001] The present invention relates to a request control device, an appropriate power consumption prediction method employed therein, and a program related to them. Background technique [0002] As a form of contract with the power company, the demander can apply a request contract. In this request contract, the contract power amount is set according to the request value. Here, the so-called request value refers to the value of the maximum required power calculated by a power meter (demand meter) every 30 minutes among the demanded power in a constant time unit (for example, 1 month). . The power meter can store the maximum required power value successively. [0003] Calculation of the basic charge which is a part of the charge to be paid to the electric power company is performed based on the contract power amount determined based on the past request value. The contracted power is set as the upper limit of the power that can be consumed every 30 minutes...
