Title:
PHOTOVOLTAIC POWER GENERATION AMOUNT PREDICTION DEVICE, CONTROL METHOD OF PHOTOVOLTAIC POWER GENERATION AMOUNT PREDICTION DEVICE, AND PROGRAM
Document Type and Number:
Japanese Patent JP2021087321
Kind Code:
A
Abstract:
To correctly predict a power generation amount of a photovoltaic power generation facility after a short time.SOLUTION: A photovoltaic power generation amount prediction device for calculating a prediction value of a power generation amount of a photovoltaic power generation facility after a predetermined time, comprises: a power generation amount storage part that stores an actual value of a power generation amount of the photovoltaic power generation facility in association with date information and weather information; a vector search part in which a date difference of each actual value is within a first date, and a time difference is within a first time, and which selects a candidate vector having the same weather information as a similar vector in regard to the latest actual value in the candidate vector and the latest actual value within a nearest vector after the search of the candidate vector in which a norm with the nearest vector having the actual value within the nearest first period as an element is a first predetermined value or less from the power generation amount storage part; and a power generation prediction part that calculates the prediction value of the power generation amount after the predetermined time of the photovoltaic power generation facility by using a precedent vector after the passing of the predetermined time from the similar vector.SELECTED DRAWING: Figure 6
