Abstract
A method for operating a power management device. The power management device controls a state of a plurality of electronic devices included in a system. The method includes obtaining an activation request to activate at least one electronic device from among the plurality of electronic devices. The method also includes predicting power consumption of the at least one electronic device. The method further includes determining schedule information to activate the at least one electronic device based on the predicted power consumption and current power consumption of the system.
Claims17
A method of operating a power management device configured to control a state of a plurality of electronic devices included in a system, the method comprising:
- obtaining an activation request to activate at least one electronic device from among the plurality of electronic devices;
- predicting power consumption of the at least one electronic device;
- identifying schedule information to activate the at least one electronic device based in part on a comparison of a threshold to a sum of the predicted power consumption of the at least one electronic device and a current power consumption of the system;
- transmitting, to the at least one electronic device, a control signal for activating the at least one electronic device, based on the schedule information;
- identifying a first value, wherein the first value is a difference in the current power consumption of the system before the at least one electronic device is activated and after the at least one electronic device is activated;
- identifying a second value, wherein the second value is a difference between the first value and the predicted power consumption of the at least one electronic device;
- determining whether the second value is within a predetermined range;
- and
- updating the schedule information based on a result of the determination,
- wherein the schedule information includes information about predicted times of activation of the at least one electronic device corresponding to the activation request and predicted times of inactivation of active electronic devices among the plurality of electronic devices.

- predict power consumption of the at least one electronic device;
- identify schedule information to activate the at least one electronic device based in part on a comparison of a threshold to a sum of the predicted power consumption of the at least one electronic device and current power consumption of the system;
- control to transmit, to the at least one electronic device, a control signal for activating the at least one electronic device, based on the schedule information;
- identify a first value, wherein the first value is a difference in the current power consumption of the system before the at least one electronic device is activated and after the at least one electronic device is activated;
- identify a second value, wherein the second value is a difference between the first value and the predicted power consumption of the at least one electronic device;
- determine whether the second value is within a predetermined range;
- and
- update the schedule information based on a result of the determination,
- wherein the schedule information includes information about predicted times of activation of the at least one electronic device corresponding to the activation request and predicted times of inactivation of active electronic devices among the plurality of electronic devices.
A non-transitory computer-readable recording medium having recorded thereon a program for operating a power management device configured to control a state of a plurality of electronic devices included in a system, the program including code that, when executed by at least one processor of the power management device, causes the power management device to:
- obtain an activation request to activate at least one electronic device from among the plurality of electronic devices;
- predict power consumption of the at least one electronic device;
- identify schedule information to activate the at least one electronic device based in part on a comparison of a threshold to a sum of the predicted power consumption of the at least one electronic device and a current power consumption of the system;
- transmit, to the at least one electronic device, a control signal for activating the at least one electronic device, based on the schedule information;
- identify a first value, wherein the first value is a difference in the current power consumption of the system before the at least one electronic device is activated and after the at least one electronic device is activated;
- identifying a second value, wherein the second value is a difference between the first value and the predicted power consumption of the at least one electronic device;
- determine whether the second value is within a predetermined range;
- and
- update the schedule information based on a result of the determination,
- wherein the schedule information includes information about predicted times of activation of the at least one electronic device corresponding to the activation request and predicted times of inactivation of active electronic devices among the plurality of electronic devices.
