ELECTRICITY DISTRIBUTION SYSTEM MANAGEMENT DEVICE, ELECTRICITY DISTRIBUTION SYSTEM MANAGEMENT SYSTEM, AND ELECTRICITY GENERATION AMOUNT ESTIMATION METHOD

摘要

The electricity distribution system management device (1) pertaining to the present invention is equipped with: a communication unit (16) for acquiring the amount of insolation, that is, measurement values measured by pyranometers, via a communication network, which is used for collecting measurement values from smart meters which measure amounts of electricity, and a meter data management device (20); and an electricity generation amount estimation unit (11) for estimating, on the basis of the amount of insolation, an amount of electricity generated by each of multiple photovoltaic power generation facilities which are connected to a power grid of a high-voltage system.
