The amount of electric energy savings may be an amount of electric energy that can be consumed from the time when the electric energy using device is automatically turned off in the control step until the time when the electric energy using device is turned on.
The time when the electric energy using device is turned on may be a time when the electric energy using device is turned on by the user or a time when the electric energy using device is automatically turned on.
The control step may automatically turn off the electric energy using device when the electric use is predicted to exceed the peak electric power.
In addition, the amount of electric energy savings may be an amount of electric energy that can be consumed for a period of time that is subtracted from the 'operation time from when the electric energy using device is automatically turned off in the control step' It can be an amount of energy.
In addition, the average operation time of the electric energy using devices may be different according to seasons or time zones.
According to another aspect of the present invention, there is provided an energy management server including: a communication unit for transmitting a command for controlling energy use to an electric energy using device; And a processor for calculating an energy saving amount by the energy use control.
INDUSTRIAL APPLICABILITY As described above, according to the present invention, it is possible to calculate the amount of electric energy savings due to the energy use control process of the electric energy using device, and it is possible to grasp the energy saving effect by the energy management system.
In addition, the amount of electric energy saved can be clearly reported, and the value and benefit of the energy management system can be clearly calculated, so that the customer and the service provider can profitably share the benefit.
In addition, the calculated electric energy savings can be used for improving the energy management system.

Then, the
FIG. 2 is a view for explaining a method of measuring electric energy savings according to another embodiment of the present invention.
As shown in FIG. 2, the
In addition, the
When the peak power is predicted to exceed the contract power or the threshold power (S530), the
Step S530 predicts the peak power in consideration of the cumulative usage amount in the peak power calculation period and the remaining cycle time. It is possible to predict that the peak power will not exceed the contract power or the threshold power even if the current cumulative usage amount is large, because the remaining cycle time is short and the peak power can be estimated as the contract power or the threshold power May be expected to exceed.
There is no restriction on the manner of selecting the air conditioners in step S540. It is possible to select the air conditioners having a long operation time up to now, the air conditioners installed at a high internal temperature, or may be selected according to a predetermined priority.
However, when the cumulative usage is large, it is desirable to select a large number of coolers / heaters or a large number of coolers / heaters with a large amount of electricity. If the cumulative usage is low, a small number of coolers / It is desirable to select the air conditioner.
In step S550, the
Meanwhile, the
In step S580, the electric energy savings are calculated and added for each cooler / heater. The amount of electric energy saved by the heating / cooling system is calculated as the amount of electric energy that can be consumed from the time when the air conditioner is automatically turned off to when the air conditioner is turned on It is possible.
At this time, the point in time when the cooling / heating device is turned on may be any of 'the time when the user turned on' or 'the time when the
The electric energy consumed in the air conditioner is calculated based on the electric energy usage amount of the air conditioner / heater received from the cooling / heating electric power measuring devices 200-1, 200-2, ..., 200-n in step S520 can do.
