POWER CONTROL APPARATUS, POWER CONTROL METHOD, AND POWER CONTROL SYSTEM
A storage cell is driven more flexibly with respect to the power supply state of a commercial grid. A power control apparatus (1) connects to a grid, is capable of controlling charging and discharging of a storage cell (22), and includes a controller (11) that performs leveling control to reduce a difference from a power purchase amount, which is established in a power purchase plan, by controlling charging and discharging of the storage cell (22). The controller (11) further performs control, upon acquiring a demand response request issued over a network, to make a comparison between the current amount of stored power in the storage cell (22) and the necessary amount of stored power for complying with the demand response request and to set a target power for power purchase in the leveling control on the basis of the result of the comparison.
POWER ADJUSTMENT DEVICE, POWER SUPPLY-DEMAND BALANCE ADJUSTMENT SYSTEM, AND POWER SUPPLY-DEMAND BALANCE ADJUSTMENT METHOD
The present power adjustment device includes: a storage device that stores vehicle information including a past behavior history of the electric vehicle participating in a VPP; and a charge-discharge instruction device for instructing the electric vehicle to charge and discharge power. The charge-discharge instruction device creates a charge-discharge plan of the electric vehicle to satisfy the power adjustment request, and instructs the electric vehicle of the created charge-discharge plan. In addition, when the charge-discharge instruction device receives an additional request of power adjustment after the instruction of the charge-discharge plan, the charge-discharge instruction device creates a change charge-discharge plan to meet the additional request, based on the estimated behavior of the electric vehicle, and the charge-discharge plan creation unit presents the electric vehicle of the charge-discharge plan that is created. The change charge-discharge plan includes information on an economic merit.

The present invention provides a planning apparatus for creating an operation plan for a hydrogen production system including a hydrogen generation apparatus, comprising: an acquisition portion for acquiring a demand response from a power operator; and an operation planning portion for creating the operation plan based on the demand response before a target period of the operation plan and at least one of a electricity price, a demand amount of hydrogen and an amount of stored hydrogen before the target period.
METHOD FOR CHARGING AN ACCUMULATOR BATTERY THROUGH A CHARGING TERMINAL
A charging method is performed to charge an accumulator battery of a vehicle. The charging method includes receiving data relating to the evolution over time of the electric power available at the charging terminal and the cost of electricity, and selecting a time window in which the cost of electricity is at a minimum. The charging method further includes estimating a temperature that the accumulator battery will have at the time of the time window and a level of charge that the accumulator battery will have before the time window, determining the electric power that the charging terminal is able to transmit to the accumulator battery during the time window, deducing a new level of charge that the accumulator battery will have at the end of the time window, comparing the new level of charge with a target level of charge, and charging the accumulator battery accordingly.
METHODS FOR USING TEMPERATURE DATA TO PROTECT ELECTRIC VEHICLE BATTERY HEALTH DURING USE OF BIDIRECTIONAL CHARGER
The present invention describes a method using temperature data to protect battery health during bidirectional charging in conjunction with monetization activities. The method includes receiving temperature data and determining anticipated energy needs of a building. The temperature data includes at least the temperature of one or more electric vehicle batteries or information required to determine the temperature of the one or more electric vehicle batteries while the anticipated energy needs are relative to ambient air temperature. The method includes determining an amount of discharge of the one or more electric vehicle batteries required to offset the anticipated needs of the building by a predetermined amount and determining based on the temperature data whether discharging the one or more electric vehicle batteries would be harmful to the health of the one or more electric vehicle batteries. The method includes discharging the one or more electric vehicle batteries to offset the anticipated needs of the building.
Method for balancing frequency instability on an electric grid using networked distributed energy storage systems
Embodiments of the present invention include control methods employed in multiphase distributed energy storage systems that are located behind utility meters typically located at, but not limited to, medium and large commercial and industrial locations. These distributed energy storage systems can operate semi-autonomously, and can be configured to develop energy control solutions for an electric load location based on various data inputs and communicate these energy control solutions to the distributed energy storage systems. In some embodiments, one or more distributed energy storage systems may be used to absorb and/or deliver power to the electric grid in an effort to provide assistance to or correct for power transmission and distribution problems found on the electric grid outside of an electric load location. In some cases, two or more distributed energy storage systems are used to form a controlled and coordinated response to the problems seen on the electric grid.
Energy control and storage system for controlling power based on a load shape
An energy control and storage system includes an energy monitor, a power controller, an energy storage device, and a computing unit. The energy monitor monitors power provided between an electric distribution system and a load. The power controller exchanges power with the energy monitor and receives power from a power generation system. The energy storage device stores energy received through the power controller. The computing unit receives a load shape from outside the energy control and storage system. The computing unit controls power exchanged between the energy control and storage system and the electric distribution system based on power indicated by the load shape that changes in response to varying conditions affecting the electric distribution system.
