Power control system, power control device, and program

A power control device included in a system for performing power control such that a target power set for a group including a plurality of consumers is not exceeded, the power control device controlling power usage of an equipment device of a consumer in the group, the power control device comprising a processor having a storage, wherein

• the processor is configured to:
• receive control information for an equipment device of each of the consumers included in the group for each of predetermined time periods, the control information including a limit value of power usage of the consumer, the limit value being set such that the target power of the group is not exceeded;
• store the control information received in the storage;
• and
• control, for each of the time periods, the power usage of the equipment device of the consumer in accordance with control information for the time period within control information stored in the storage,
• wherein the processor is further configured to transmit pieces of control information for respective equipment devices of the plurality of consumers included in the group for a time period to the power control device that controls the equipment devices to be controlled by using the pieces of control information, wherein
• a first group of the equipment devices receives the pieces of control information for decreasing the limit values for the time period compared with the limit values for a time period immediately preceding the time period,
• a second group of the equipment devices receives the pieces of control information for increasing the limit values for the time period compared with the limit values for the time period immediately preceding the time period, and
• the pieces of control information for respective equipment devices are transmitted to the first group of the equipment devices earlier than to the second group of the equipment devices.

A non-transitory computer readable medium storing a program for causing a computer for controlling a power control device included in a system for performing power control such that a target power set for a group including a plurality of consumers is not exceeded, the power control device controlling power usage of an equipment device of a consumer in the group, to perform functions of:

• receiving control information for an equipment device of each of the consumers included in the group for each of predetermined time periods, the control information including a limit value of power usage of the consumer, the limit value being set such that the target power of the group is not exceeded;
• controlling, for each of the time periods, the power usage of the equipment device of the consumer in accordance with control information for the time period within control information stored in a storage of the computer that stores the control information received;
• and
• transmitting pieces of control information for respective equipment devices of the plurality of consumers included in the group for a time period to the power control device that controls the equipment devices to be controlled by using the pieces of control information, wherein
• a first group of the equipment devices receives the pieces of control information for decreasing the limit values for the time period compared with the limit values for a time period immediately preceding the time period,
• a second group of equipment devices receives the pieces of control information for increasing the limit values for the time period compared with the limit values for the time period immediately preceding the time period, and
• the pieces of control information for respective equipment devices are transmitted to the first group of the equipment devices earlier than to the second group of the equipment devices.
