Abstract
A power management system comprises a plurality of HEMSs 10 and a CEMS 40. The CEMS 40 transmits, to each HEMS 10, a notification request for requesting a notification of an amount of power that can be reduced from power currently consumed by a load connected to each HEMS 10, in response to a power curtailment signal. Each HEMS 10 transmits, to the CEMS 40, reducible power information including the amount of power that can be reduced from the power currently consumed, in response to the notification request. The CEMS 40 transmits, to each HEMS 10, power reduction information including an amount of power that should be reduced in each consumer 70, in response to the power curtailment signal and the reducible power information.
Claims13
A power management system comprising;
- a plurality of lower power management apparatuses, wherein each of the plurality of lower power management apparatuses is associated with one of a plurality of consumers;
- and
- an upper power management apparatus that manages the plurality of lower power management apparatuses,
- wherein the upper power management apparatus, in response to a power curtailment signal transmitted from a power company that manages a power grid, transmits, to each of the plurality of lower power management apparatuses, a notification request for an amount of power that can be reduced from current power consumed by loads connected to each of the plurality of lower power management apparatuses,
- wherein each of the plurality of lower power management apparatuses, in response to the notification request, transmits, to the upper power management apparatus, reducible power information including the amount of power that can be reduced from the current power related to at least one category out of a plurality of categories of loads, and
- wherein the upper power management apparatus, in response to the power curtailment signal and the reducible power information, transmits, to each of the plurality of lower power management apparatuses power reduction information including an amount of power that should be reduced in each consumer.
A power management method applied to a power management system comprising a plurality of lower power management apparatuses, each of which is associated with one of a plurality of consumers, and an upper power management apparatus that manages the plurality of lower power management apparatuses, the power management method comprising:
- in response to a power curtailment signal transmitted from a power company that manages a power grid, transmitting, from the upper power management apparatus to each of the plurality of lower power management apparatuses, a notification request for requesting a notification of an amount of power that can be reduced from current power consumed by loads connected to each of the plurality of lower power management apparatuses;
- in response to the notification request, transmitting, from each of the plurality of lower power management apparatuses to the upper power management apparatus, reducible power information including the amount of power that can be reduced from the current power related to at least one category out of a plurality of categories of loads;
- and
- in response to the power curtailment signal and the reducible power information, transmitting, from the upper power management apparatus to each of the plurality of lower power management apparatuses, power reduction information including an amount of power that should be reduced in each consumer.
An upper power management apparatus that manages a plurality of lower power management apparatuses each of which is associated with one of a plurality of consumers, comprising:
- a transmitter configured to, in response to a power curtailment signal transmitted from a power company that manages a power grid, transmit, to each of the plurality of lower power management apparatuses, a notification request for an amount of power that can be reduced from current power consumed by loads connected to each of the plurality of lower power management apparatuses;
- and
- a receiver configured to, in response to the notification request, receive, from each of the plurality of lower power management apparatuses, reducible power information including an amount of power that can be reduced from the current power related to at least one category out of a plurality of categories of loads,
- wherein the transmitter is configured to, in response to the power curtailment signal and the reducible power information, transmit, to each of the plurality of lower power management apparatuses, power reduction information including an amount of power that should be reduced in each consumer.
