PHOTOVOLTAIC POWER GENERATION AMOUNT ESTIMATION SYSTEM, ESTIMATION METHOD AND PHOTOVOLTAIC POWER GENERATION SYSTEM CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a photovoltaic power generation amount estimation system, an estimation method and a photovoltaic power generation system control system, which are low cost and capable of highly accurately calculating a photovoltaic power generation amount in a short period and reliability thereof.SOLUTION: The photovoltaic power generation amount estimation system is equipped with: communication means for obtaining a power generation amount of a photovoltaic power generator connected to a power distribution system at a fixed period; a first database storing time-series data on the power generation amount; a second database storing map information on an area including the power distribution system; a third database storing weather information on an area including the power distribution system; arithmetic means; and a monitor. The arithmetic means uses weather information and map information on an area including installed positions of a first photovoltaic power generator and a second photovoltaic power generator which are connected to the power distribution system, and time-series data on a measured photovoltaic power generation amount to obtain an estimated power generation amount of the second photovoltaic power generator at estimated time together with information on reliability of the estimation.
