Abstract

Provided is a network system. The network system includes: at least one unit selected from an energy receiving unit receiving energy and an energy management unit managing the energy receiving unit. An energy usage amount or energy usage rate of the energy receiving unit is adjusted; an energy usage amount or usage rate when the unit is controlled based on information relating to at least an energy rate is less than that when the unit is controlled without the base of information relating to at least an energy rate; the energy receiving unit comprises a plurality of components; and an operation of one component among the plurality of components is controlled based on the energy rate related information.

Claims

1. An energy consumption unit capable of communicating with a network system and capable of receiving energy information related to Information related to time-based pricing and information other than information related to time-based pricing, the energy consumption unit comprising:

a plurality of assigned priorities;

wherein;

an operation of a component is adjusted based on a priority among the plurality of assigned priorities, the energy information related to the information related to time-based pricing, and the information other than information related to time-based pricing, wherein the operation of the component being adjusted based on the energy information comprises adjusting driving intervals of a plurality of components at different time intervals,

wherein the different time intervals have different energy rates,

wherein the plurality of components includes a first component and a second component having a larger power consumption per unit hour or energy usage rate than that of the first component,

wherein the second component is driven at an energy rate interval lower than that at which the first component is driven,

wherein the energy rate interval in which the second component is driven is on a basis of a setting value, the setting value is an energy rate previously accumulated during a driving period of the first component,

wherein the setting value includes a first reference value and a second reference value, the second reference value is greater than the first reference value,

when the energy rate is less than the first reference value, the second component is driven,

when the energy rate is greater than the first reference value and less than the second reference value, the driving of the second component is stopped, the first component is driven, and

when the energy rate is greater than the second reference value, the driving of the first component and the second component is stopped.

2. The energy consumption unit according to claim 1, wherein the different time intervals comprise at least one of driving start times and end times of the plurality of components are different.

3. The energy consumption unit according to claim 2, wherein among the plurality of components, one component and another component have the same driving start time and different end times.

4. The energy consumption unit according to claim 2, wherein among the plurality of components, one component and another component have different driving start times and the same end time.

5. The energy consumption unit according to claim 1, wherein some intervals in the driving intervals of the plurality of components overlap.

6. The energy consumption unit according to claim 5, wherein the driving intervals of the plurality of components comprises a time interval at which both one component and another component are driven.

7. The energy consumption unit according to claim 1, wherein driving of one component among the plurality of components starts after driving of another component is terminated.
