A control method of the power generation system of the disclosure is a control method of a power generation system configured with a power generation apparatus and at least one other power generation apparatus coupled to the power generation apparatus herein, the power generation system configured to interconnect with a grid and supply power to a load, wherein a process performed by the power generation apparatus includes a step of obtaining a current value between the power generation system and the grid, a step of determining, based on the current value, respective target power to be generated by the power generation apparatuses, and the other power generation apparatuses, and a step of notifying the other power generation apparatuses of the respective target power.

Control method of power generation system, power generation system, and power generation apparatus

In order to provide means to improve an operating ratio and the like of a fuel cell while keeping using a gas meter and a gas leakage detection system popularly used by a general household, a fuel cell system of the disclosure herein including a fuel cell module configured to generate power by using gas supplied via a gas meter and a controller configured to control the power generation of the fuel cell module, wherein the controller, when detecting for a first predetermined period of time that the gas is not supplied to anything else other than the fuel cell module, controls to stop the power generation of the fuel cell module for a second predetermined period of time.

Fuel cell system, control method of fuel cell system, and fuel cell control apparatus

A power conversion apparatus, power conversion method, and a power conversion system can reduce the occurrence of unnecessary power loss. The power conversion apparatus converts direct current (DC) power supplied by a solar cell into alternating current (AC) power. The power conversion apparatus includes a DC filter unit, a memory, and a controller. The DC filter unit includes a noise filter that reduces noise in the DC power supplied by the solar cell and a switch that connects an input terminal and an output terminal of the noise filter. The controller controls the switch in accordance with output power of the DC filter unit.

An energy management apparatus capable of taking an appropriate measure in the event of a power failure and a method of controlling the energy management system will be provided. A storage medium, a power input unitfor receiving power supply, a backup power sourcefor supplying power when power supply to the power input unitfrom a grid power sourcestops, and a control unit, when the power supply to the power input unitfrom the grid power sourcestops for a period equal to or longer than a predetermined period, for carrying out a suspension processing of the storage mediumare provided.

Energy management apparatus and method of controlling the same

An information processing apparatus includes a first display controller, an accepting unit, a grouping unit, and a memory controller. The first display controller controls a display to display plural images representing respective files. The accepting unit accepts an operation for selecting at least two or more images from among the plural images. The grouping unit forms a group by associating plural files represented by the at least two or more images with one another with the at least two or more images kept displayed on the display in a case where the accepting unit has accepted the operation. The memory controller controls a memory to store information indicating display positions of the at least two or more images on a screen in association with the group that has been formed by the grouping unit.

Information processing apparatus, information processing method, and non-transitory computer readable medium

A power supply system comprises a plurality of distributed power source systems capable of supplying powers to loadsby performing an interconnection operation in parallel with gridor an offline self-sustained operation. SOFC systemdetects an abnormal state of the power supplied to loads. SOFC systemeases the abnormality detection conditions during the self-sustained operation than during the interconnection operation.
