Application Number: JP,2024-195814
Category (FI): H02S50/00
Stage: PROBLEM TO BE SOLVED: To enable accurate evaluation of the operating status of photovoltaic power generation and accurate determination of photovoltaic power generation abnormalities, so as to provide a new perspective on the operation management of a photovoltaic power plant.SOLUTION: In a step S101, operation data of a photovoltaic power plant is acquired, and a preset machine learning model is trained on the basis of the past operation data of the photovoltaic power plant to generate a photovoltaic power generation prediction model. In a step S102, the photovoltaic power generation prediction model is used to obtain a power amount to be generated on a current day, and daily power generation fluctuation evaluation and power generation efficiency evaluation are performed on each of the multiple photovoltaic power plants to determine which photovoltaic power plants have an abnormal power generation situation. In a step S103, the operation data corresponding to the photovoltaic power plant where the abnormal power generation situation exists is compared with diagnosis determination conditions to generate a photovoltaic power generation abnormality diagnosis result.SELECTED DRAWING: Figure 1 (Grant)
