A power saving control device includes: an acquirer that acquires a power saving request; and a controller that determines whether or not power saving control for reducing a power consumption of a load device is to be performed in response to the power saving request, and that, when determining that the power saving control is to be performed, performs the power saving control. When the load device consumes power, the controller determines that the power saving control is not to be performed under a condition that no power flows from a power system into a facility in which the load device is installed, the condition being one of one or more conditions.

Power saving control device and power saving control method

A power management method includes: receiving a surplus power value, indicating an amount of surplus power; receiving an inquiry regarding a power supply using the surplus power in a first time period; and issuing, in accordance with the inquiry, first power identification information in association with an accumulated value of the amount of surplus power corresponding to the first time period, the first power identification information allowing a power supply apparatus to supply power using the surplus power corresponding to the first time period. When a first power supply request associated with the first power identification information and requesting a power supply to a first load is received, the power supply apparatus is caused to supply an amount of power equal to or smaller than the accumulated value of the amount of surplus power, to the first load, as first power that does not cause a fee charging process.

Power management method, power management system, and power supply apparatus

Power management device includes memory, classification portion, planning portion and indication portion. Classification portion classifies a change in monitoring power during a unit period with respect to each of buildings, stored in memory, into any one of kinds of electric power patterns. Planning portion determines pattern sets based on the kinds of electric power patterns, and determines control content for charging and discharging of electric storage apparatus with respect to each pattern set under condition of minimizing any one of amount of electric power to be received from power grid, compensation of amount of electric power to be received from power grid, and amount of carbon dioxide to be exhausted. Indication portion indicates control content corresponding to each of pattern sets determined by planning portion to electric storage apparatus of a building, which each pattern set conforms with, of the buildings.

A charge/discharge control apparatus includes: a controller which performs a discharge control to discharge a rechargeable battery and a charge control to charge the rechargeable battery using excess power which is power, among generated power, which is not to be consumed by a load; and a setter which sets a threshold value for remaining energy in the rechargeable battery, according to a planned discharged energy amount which is planned as a discharged energy amount to be supplied from the rechargeable battery to the load during a specified time period. The controller performs a discharge prohibition control to prohibit a discharge of the rechargeable battery when the remaining energy in the rechargeable battery is equal to or below the threshold value prior to the specified time period.

Charge/discharge control apparatus

A power adjustment device supplies power received from a power grid and power of a storage battery to an electric load in a consumer's facility. Power adjustment device includes a prediction portion, a planning portion, and a controller. Prediction portion obtains a prediction value of demand power that is power to be consumed in the electric load in a planning period, the planning period being a period in which the storage battery is charged and discharges. Planning portion determines a control content of charging of and discharging by the storage battery in the planning period depending on the prediction value of the demand power to minimize any one of an amount of power to be received from the power grid, a compensation for power to be received from the power grid, and an emission amount of carbon dioxide. Controller controls the power conditioner in accordance with the control content.

A power management method receives, from a meter that measures the amount of surplus power, which is power supplied from a power generation apparatus to a power system, a surplus power value indicating the amount of surplus power, receives, from a first communication terminal used by a user corresponding to first user identification information, an inquiry about power supply in which the surplus power is used in a first time period that lasts a certain unit time, the inquiry being associated with the first user identification information, issues, in accordance with the inquiry, first power identification information for validating power supply performed by a power supply apparatus using the surplus power corresponding to the first time period for an accumulated value of the amount of surplus power corresponding to the first time period, transmits the first power identification information and the accumulated value of the amount of surplus power corresponding to the first time period to the first communication terminal, and causes the power supply apparatus that has received a first power supply request, which is associated with the first power identification information, indicating that power is to be supplied to the first load apparatus to supply an amount of first power equal to or smaller than the amount of surplus power to the first load apparatus as power that does not cause a charging process.

A vehicle-mounted apparatus comprising: a communication unit which is connected to the charger/discharger and exchanges information with the charger/discharger; an input unit receiving various types of information; a storage unit which uses the information acquired through the input unit and the communication unit to store: a vehicle ID identifying the vehicle; a charger/discharger ID identifying the charger/discharger which can be connected to the vehicle; and history information indicating a history of charges and discharges for the vehicle, which are related to one another; and a presentation unit presenting to a user of the vehicle, the history information stored in the storage unit in relation to a pair of the vehicle ID and the charger/discharger which charges/discharges the vehicle and is identified by the charger/discharger ID.
