A power distribution control apparatus includes a power source switcher that switches a power source for supplying electric power to a plurality of load groups between a commercial power source and a battery, control circuitry that controls the power source switcher and a plurality of switches provided in power supply paths between the power source switcher and each of the load groups, and a memory that stores positions of the plurality of switches in the order of priority. When the power source switcher switches to the commercial power source and a power saving time zone in which commercial power consumption is to be reduced is reached, the control circuitry controls the switches to be in a non-conducting state, switches the power source from the commercial power source to the battery using the power source switcher, and sequentially controls the switches in a conducting state in the order of priority.

Power distribution control apparatus, electricity storage system, and power distribution control method

A power control apparatus includes the following elements. A measure measures a value of a current to be supplied from a power supply source to a load set. A switch is disposed on a power supply path from power supply source to a load set. A setter sets a first maximum current value in the case of a normal state in which the load set receives power from a main power supply source and sets a second maximum current value when the load set receives power from the sub power supply source. Control circuitry turns OFF the switch when the value of the measured current exceeds the first maximum current value in the case of the normal state and turns OFF the switch when the load set receives power from the sub power supply source and the value of the measured current exceeds the second maximum current value.

A storage battery monitoring method receives identification information indicating a storage battery system and characteristic data of a storage battery, the characteristic data including history information which indicates charging and discharging history of the storage battery; determines, based on the received history information, a deterioration model corresponding to the storage battery from among deterioration models managed in a database, the deterioration models each indicating a relationship between a state of health and a number of charging and discharging cycles performed by the battery as indicated by the charging and discharging history; generates control data for suppressing deterioration of the storage battery at a predetermined point in time according to the corresponding deterioration model; and transmits the generated control data to cause the storage battery system to control the storage battery.

Storage battery monitoring method, storage battery monitoring system, and storage battery system

A frequency regulation method for a grid which is performed by a control device that connects, through a communication network, a controller for controlling at least one load device and a storage battery. The frequency regulation method including: obtaining, when it is detected that a frequency of a grid deviates from a predetermined range, an instruction signal including a power instruction value for keeping the frequency of the grid within the predetermined range; and generating a control signal for controlling the load device when the load device is operable in accordance with the instruction signal, and transmitting the control signal to the controller, and generating a control signal for charging or discharging the storage battery when the load device is not operable in accordance with the instruction signal, and transmitting the control signal to the storage battery.

In a digital camera, when snapshot shooting is instructed during recording of a moving image, a shot still image is temporarily pushed aside in a memory area for use in pushing aside () in a frame buffer (). A currently shooting motion image and a still image are displayed in parallel on a display (), so that a user can confirm a content of a snapshot. The moving image continues to be recorded even during a push-aside operation. After a moving image processing is completed, the still image is processed by an image correcting circuit (). The frame buffer () comprises a plurality of frame recording areas, and is shared on the occasions of a moving image processing and a still image processing. In a normal moving image processing, these areas are utilized in a cyclic manner, and when the still image is shot, any of areas will be utilized. Thereafter, the rest of areas are utilized in the cyclic manner for the moving images. The recording function for the moving image and still image is improved at low cost, it becomes easy to take a snapshot, and the merchandise size is not increased.
