    Abstract: Inrush current to a load at the time of a power outage is reduced. A power control apparatus includes an inverter and a controller. When the controller detects a power outage in a power grid, the controller performs control so that output voltage supplied from the inverter to a switching device rises to an operating voltage. The operating voltage is the voltage at which the switching device operates to switch from electric power supplied to load devices from the power grid to electric power from the inverter. The controller also performs control to maintain the output voltage at or below the operating voltage when the output voltage reaches the operating voltage and then performs control so that the output voltage rises to a predetermined voltage exceeding the operating voltage.

    Abstract: A resource recovery system is a system for recovering articles which can be recycled as resources. The resource recovery system includes a resource recovery apparatus that recovers the article discarded by a consumer, and a server apparatus that communicates with the resource recovery apparatus. The resource recovery apparatus transmits, to the server apparatus, a first message including an article identifier for identifying the recovered article. The server apparatus associates, based on the first message received from the resource recovery apparatus, a discarding time when the article is discarded with a provision time when the article is provided to the consumer.

    Abstract: A power management apparatus manages a facility including a stop space. The stop space includes charge-discharge equipment that performs charge and discharge of a storage battery apparatus provided in an electric mobile body. The power management apparatus includes: a receiver configured to receive a permission message indicating that at least one of the charge or discharge of the storage battery apparatus is permitted; a manager configured to manage a remaining storage amount of the storage battery apparatus for which the at least one of the charge and discharge is permitted by the permission message, when the storage battery apparatus is connected to the charge-discharge equipment; and a controller configured to control the charge-discharge equipment for performing the at least one of the charge and discharge of the storage battery apparatus, based on the remaining storage amount of the storage battery apparatus that is managed by the manager.

    Abstract: A power supply apparatus, a power supply system, and a power supply method increase the power generation efficiency of the system overall in a system that includes a plurality of power source units. A power supply apparatus operates distributed power sources in parallel, the distributed power sources including power source units, and supplies output power from the distributed power sources to a load. The power supply apparatus includes a controller that controls each power source unit so that output power from whichever of the power source units has higher power generation efficiency is prioritized to increase.
