  • Publication number: 20240405551
    Abstract: A base station management device (10) for managing at least one base station (20) including a solar power generation device (21) and a storage battery (22) and being capable of executing response to DR and self-wheeling of generated power includes: a power generation amount prediction unit (13) deriving a power generation amount prediction value of the base station at a prediction target time, based on a power generation amount actual value, weather information when the actual value has been obtained, and a weather forecast value of the prediction target time; and a schedule creation unit (14) that creates a schedule of self-wheeling of generated power based on the power generation amount prediction value of the base station, selects, in a case where a DR notification is given, one of the self-wheeling and the response to DR having a higher effect, and creates a schedule for implementing the method.

  • Patent number: 10308670
    Abstract: The purpose of the present invention is to provide silanol compounds that can be used as raw materials of siloxane compounds and the like, and a composition of the silanol compounds, as well as to provide a production method that makes it possible to produce silanol compounds at excellent yield. A composition comprising 5 mass % to 100 mass % of a silanol compound represented by Formulas (A) to (C) can be prepared by devising to produce silanol compounds under water-free conditions, to produce silanol compounds in a solvent having the effect of suppressing the condensation of silanol compounds, and to perform other such processes, the composition being able to be used as a raw material or the like of siloxane compounds because the silanol compounds can be stably present in the resulting composition.

  • Publication number: 20170275171
    Abstract: An object of the present invention is to provide a method for producing oligosilane and in particular to provide a method that can efficiently produce oligosilane at lower temperatures and with an improved yield and selectivity. In the dehydrogenative coupling reaction of hydrosilane, oligosilane can be efficiently produced at an improved selectivity for oligosilane, and in particular at an improved selectivity for disilane, by carrying out the reaction in the presence of zeolite having pores with a minor diameter of at least 0.43 nm and a major diameter of not more than 0.69 nm.
