POWER CONTROL APPARATUS, POWER CONTROL SYSTEM, AND CONTROL METHOD
First Claim
1. A power control apparatus connecting to equipment provided in a consumer through a communication network and controlling the equipment, comprising:
- a transmission unit that transmits control information for controlling the equipment to the equipment in each predetermined cycle; and
a control unit that controls a transmission of the control information, whereinthe control unit is configured to make the transmission unit retransmit the control information to the equipment when a response period from a transmission of the control information, which is from the transmission unit to the control unit, to a reception of response information corresponding to the control information is longer than a timeout period which is set to be a shorter period than the predetermined cycle; and
whereinthe control unit is configured to change the timeout period by controlling a retransmission possible frequency of the control information, within a period of the predetermined cycle from the transmission of the control information from the transmission unit to the equipment.

Abstract
A HEMS 200 connects to equipment provided in a consumer through a communication network and controls the equipment. The HEMS 200 comprises a transceiver unit 210 transmitting control information for controlling the equipment to the equipment in each control cycle T and a control unit 240 controlling a transmission of the control information; the control unit 240 controls the transceiver unit 210 to retransmit the control information to the equipment when response information corresponding to the control information is not received within a timeout period t set to be shorter than the control cycle T from the transmission of the control information from the transceiver unit 210. The control unit 240 changes the timeout period t by controlling a retransmission possible frequency of the control information within the period of the control cycle T.

9. A control method in a power control apparatus that connects to equipment provided in a consumer through a communication network and controls the equipment, comprising:
-
a step A of transmitting control information for controlling the equipment to the equipment in each predetermined cycle; a step B of retransmitting the control information to the equipment when a response period from a transmission of the control information, which is to the equipment, to a reception of response information corresponding to the control information is longer than a timeout period which is set to be shorter than the predetermined cycle; and a step C of changing the timeout period by changing a retransmission possible frequency of the control information within the period of the predetermined cycle from the transmission of the control information to the equipment.
