Abstract: A power control apparatus includes: a first conversion apparatus that applies DC/DC conversion to direct current power from a power generator for generating power using natural energy, and outputs the resultant power; a second conversion apparatus that applies DC/DC conversion to the power output from the first conversion apparatus and charges a power storage unit with the resultant power, and also applies DC/DC conversion to power from the power storage unit and discharges the resultant power; a third conversion apparatus that supplies alternating current power to a power system and an alternating current load by applying DC/AC conversion to the power output from the first conversion apparatus and/or the power discharged by the second conversion apparatus; and a controller that causes the second conversion apparatus to perform the discharge so that the power output from the third conversion apparatus is higher than power consumed by the alternating current load.

Abstract: A generated power estimation model to be used for estimating an expected generated power amount that is expected to be generated by a solar power generation module is constructed based on a daily correlative relationship between a generated power amount generated by a solar power generation module that generates power by receiving sunlight, and an energy amount of sunlight emitted to the solar power generation module. Furthermore, the expected generated power amount is estimated based on the generated power estimation model, and it is determined whether or not an abnormality has occurred by comparing the expected generated power amount and the generated power amount actually generated by the solar power generation module. This technique can be applied to a solar power generation system, for example.

Abstract: A storage unit stores a defect correlation table indicating what influence a given type of defect will have on the inspection of the other types of defects. When an obtainment unit obtains an inspection result of inspecting for a defect, an influence determination unit refers to the defect correlation table and determines the influence of the other types of defects on the inspection result. Information pertaining to the determined influence is outputted via an output unit.
