Power consumption management device, power consumption management system, power consumption management method, and power consumption management program

A power consumption management system comprising:

• a plurality of power consumption management devices, each of which includes
• a power measurement unit configured to measure an actual power consumption value of an electrical device, and
• an environmental factor measurement unit configured to measure a factor of an environment in which the electrical device is used;
• and
• a computer configured to be connected to each power consumption management device via a communication line and include a storage unit and a calculation/control unit, the storage unit configured to store a predicted value related to the power consumption in which a value of the factor of the environment is designated as a parameter, the predicted value being based on at least one of a non-measured original predicted value and a previously measured power consumption value of the electrical device,
• wherein the calculation/control unit obtains a predicted value related to the power consumption stored in a storage unit based on a value of the factor of the environment measured by the environmental factor measurement unit of each power consumption management device, compares the obtained predicted value to the actual power consumption value, and transmits a comparison result to the power consumption management device via the communication line,
• wherein, when a value of [(the actual power consumption value)−(the predicted value)] is in a prescribed range, the calculation/control unit replaces the predicted value stored on the storage unit with an updated predicted value that is based on the actual power consumption value, while designating the value of the factor of the environment measured by the environmental factor measurement unit as the parameter, wherein the updated predicted value is an average of the actual power consumption value and the predicted value,
• wherein, when a value of [(the actual power consumption value)−(the predicted value)] is out of a prescribed range, the calculation/control unit issues a warning, but does not replace the predicted value stored on the storage unit with an updated predicted value, and
• wherein the warning is issued as a sound, an image displayed on a display device, or a video displayed on a display device.

A power consumption management method comprising:

• measuring an actual power consumption value of an electrical device;
• storing a predicted value related to power consumption in which a value of a factor of an environment is designated as a parameter in a storage unit, the predicted value being based on at least one of a non-measured original predicted value and a previously measured power consumption value of the electrical device;
• obtaining the predicted value related to the power consumption stored in the storage unit based on a measurement result of the factor of the environment in which an electrical device is used;
• comparing the obtained predicted value to the actual power consumption value,
• wherein, when a value of [(the actual power consumption value)−(the predicted value)] is in a prescribed range, the calculation/control unit replaces the predicted value stored on the storage unit with an updated predicted value that is based on the actual power consumption value, while designating the value of the factor of the environment measured by the environmental factor measurement unit as the parameter, wherein the updated predicted value is an average of the actual power consumption value and the predicted value,
• wherein, when a value of [(the actual power consumption value)−(the predicted value)] is out of a prescribed range, the calculation/control unit issues a warning, but does not replace the predicted value stored on the storage unit with an updated predicted value, and
• wherein the warning is issued as a sound, an image displayed on a display device, or a video displayed on a display device.

A power consumption management program stored on a non-transitory computer readable storage medium, which when executed, causes a computer to:

• measure an actual power consumption value of an electrical device
• store a predicted value related to power consumption in which a value of a factor of an environment is designated as a parameter in a storage unit, the predicted value being based on at least one of a non-measured original predicted value and a previously measured power consumption value of the electrical device;
• obtain the predicted value related to the power consumption stored in the storage unit based on a measurement result of the factor of the environment in which an electrical device is used;
• and
• compare the obtained predicted value to the actual power consumption value,
• wherein, when a value of [(the actual power consumption value)−(the predicted value)] is in a prescribed range, the calculation/control unit replaces the predicted value stored on the storage unit with an updated predicted value that is based on the actual power consumption value, while designating the value of the factor of the environment measured by the environmental factor measurement unit as the parameter, wherein the updated predicted value is an average of the actual power consumption value and the predicted value,
• wherein, when a value of [(the actual power consumption value)−(the predicted value)] is out of a prescribed range, the calculation/control unit issues a warning, but does not replace the predicted value stored on the storage unit with an updated predicted value, and
• wherein the warning is issued as a sound, an image displayed on a display device, or a video displayed on a display device.
