A power management system includes a plurality of power storages and a server. The server includes a selector that selects at least one of the plurality of power storages, a scheduler that makes a schedule for the selected power storage, and a request processor that requests a user of the selected power storage to control at least one of external charging and external power feed in accordance with the made schedule. The server obtains desire information that indicates a desire level (priority on battery life/priority on an incentive) and carries out at least one of selection of the power storage and making of the schedule based on the obtained desire information.

Demand response methodologies for primary frequency response (PFR) for under or over frequency events. Aspects of the present disclosure include methods for controlling a fleet of distributed energy resources equipped for PFR and quantifying in real time an amount of primary frequency control capacity available in the fleet. In some examples, the DERs may be configured to consume and discharge electrical energy in discrete energy packets and be equipped with a frequency response local control law that causes each DER to independently and instantaneously interrupt an energy packet in response to local frequency measurements indicating a grid disturbance event has occurred.

A system and method for power pooling, the system including a shared power line, a plurality of backup power supplies connected to the shared power line through respective transformers and one or more controllers configured to, for each respective backup power supply, after passage of a different respective predetermined amount of time, determine whether a transformer connected to the backup power supply is energized. In response to the transformer being energized, the controllers synchronize the backup power supply with the transformer and then set a switch positioned between the backup power supply and the transformer to a fully closed state. In response to the transformer not being energized, the controllers transition the switch from a fully open state to the fully closed state according to an inrush current limiting scheme.

A power management method includes a step A of transmitting a power command message for controlling a distributed power supply from a power management server to a local control apparatus, the power management server managing a plurality of facilities, the distributed power supply being individually provided in each facility, and the local control apparatus being individually provided in each facility, wherein the step A includes a step of transmitting the power command message based on a specifying result or an estimating result of a local operation plan of the distributed power supply in each facility.

A device control apparatus performs demand response control in which an amount of energy consumed in a predetermined time slot by a facility device is adjusted in accordance with an adjustment request. The device control apparatus includes a reception unit that accepts an operation instruction for the facility device, an expense effect presentation unit and a comfort effect projection. The expense effect presentation unit presents an expense effect incurred on a charge in association with the amount of energy consumed by the facility device through an activity based on the operation instruction. The comfort effect projection unit projects an effect on comfort incurred in a space surrounding the facility device in association with the amount of energy consumed by the facility device through the activity based on the operation instruction.

Systems, methods, and controllers for controlling an adjustment process for a target system are provided. A central controller receives time-related electrical energy demand data, sensor data from controllers of devices which selectively apply electrical power to the target system, and commands the controllers to apply power to exceed a target control value up to a maximum control value where the electrical energy demand data remains below a threshold and only apply sufficient energy to reach the target control value, at least within a margin, where the electrical energy demand data remains above the threshold.

Systems and methods for integrating demand response with service restoration in an electric distribution system. The electric distribution system may include a plurality of regions, zones, and/or areas including at least an outage area that includes a fault and is not receiving electric current from the electric distribution system and a restoration area that is receiving electric current from the electric distribution system and that may be selectively configured to provide electric current to a selected portion of the outage area. The electric distribution system also includes a plurality of demand responsive loads configured to be selectively isolated from the electric distribution system responsive to a load shed signal. The demand responsive loads may be selectively utilized during service restoration, such as to provide additional excess capacity within the restoration area and/or decrease a magnitude of the electric load applied by the selected portion of the outage area.

A demand monitoring device which monitors an amount of electric power received by a consumer includes: a prediction unit predicting, every demand period, received electric power in the object demand period on the basis of at least one of demand electric power, generated electric power, and received electric power at a time previous to the demand period, a known schedule of the consumer in the demand period, and weather information; a creation unit creating a graph showing an amount of electric power received by the consumer until a current time, a predicted value for an amount of received electric power from the current time onward, the predicted value being predicted by the prediction unit, and a target electric power amount based on contract electric power of the consumer; and a display control unit displaying the graph created by the creation unit, on a screen of a display device.

According to the inventive method, the power consumed on an electric grid (10), by preselected consumers (42, 44, 46, 48, 50, 52) being able to accept a predetermined decrease in power over a predetermined time range, is regulated. This method comprises the following successive steps: sending a control entity, regularly and by each preselected consumer (42, 44, 46, 48, 50, 52), a message (M1) containing the power consumed by said preselected consumer (42, 44, 46, 48, 50, 52); using the control entity (60) to compute a maximum power reduction value for all of the preselected consumers (42, 44, 46, 48, 50, 52) and a maximum duration of that power reduction; transmitting, using the control entity (60) and to a grid manager (62), computed values and maximum power durations; and sending, from the grid manager (62) to the control entity (60), a command order (79) commanding a power reduction for a selected duration.
