A power management method, comprising:

• a step A for receiving a power control message from an external server;
• a step B for controlling at least any one of a power flow amount from a power grid to a facility and a reverse power flow amount from the facility to the power grid based on the power control message;
• and
• a step C for transmitting a control result of at least any one of the power flow amount and the reverse power flow amount to the external server, wherein
• the control result includes control amount information indicating a control amount of at least any one of the power flow amount and the reverse power flow amount and identification information for identifying a contributing equipment that contributes to control of at least any one of the power flow amount and the reverse power flow amount.

A power management system, comprising:

• a receiver configured to receive a power control message from an external server;
• a controller configured to control at least any one of a power flow amount from a power grid to a facility and a reverse power flow amount from the facility to the power grid based on the power control message;
• and
• a transmitter configured to transmit a control result of at least any one of the power flow amount and the reverse power flow amount to the external server, wherein
• the control result includes control amount information indicating a control amount of at least any one of the power flow amount and the reverse power flow amount and identification information for identifying a contributing equipment that contributes to control of at least any one of the power flow amount and the reverse power flow amount.
