Solar power generation equipment amount prediction system, solar power generation equipment amount prediction method and weather prediction system

摘要

It is another object to remove the influence of the voltage distribution of the power distribution system, to provide predictable photovoltaic power generation facility prediction system with high accuracy the amount of power generated by the photovoltaic installation. In solar power generation facility amount prediction and weather forecasting system 500, solar power generation equipment amount correction unit 570, power loss due shadow voltage increase and suppression control, the amount of power generation Past results of each solar power plant 220 by removing the influence of, is determined as actual power generation amount correction value to the amount of power generation when there is no influence thereof. Solar power generation equipment between power generation amount correlation model identification unit 550, to identify the correlation model between the actual amount of power correction value of past solar power equipment 220 multiple. By using the correlation model, solar power generation equipment amount prediction unit 560, to predict the amount of power generated by the future time of each solar power plant 220. Weather information converting unit 590 converts the intensity of solar radiation the predicted value of the power generation.
