Abstract

The invention provides a solar energy resource short-term and imminent forecasting method based on a satellite radiation product. The method comprises the following steps: acquiring historical solar radiation data corresponding to a current period; establishing a solar radiation value forecasting model based on a mean generation function according to the historical solar radiation data corresponding to the current period; outputting an initial solar radiation forecast value in a forecast time period of the current period according to the forecast model. From a second period, the solar resource short-term and imminent forecasting method further comprises the following steps: correcting an initial solar radiation forecast value in a forecasting time period of a current period by using a ground observation solar radiation value in a forecasting time period corresponding to a previous period; and obtaining a final solar radiation forecast value in the forecast time period of the current period.

Description

technical field [0001] The present invention relates to the field of solar resource forecasting, in particular to a short-impending solar resource forecasting method based on satellite radiation products, a computer-readable storage medium and an electronic device. Background technique [0002] In recent years, with the increasingly prominent environmental and energy issues, photovoltaic power generation, as a new energy source, has developed particularly rapidly. Surface solar irradiance is the most direct climatic factor affecting the power of photovoltaic power generation. However, surface solar irradiance changes periodically and randomly with seasons and weather. Therefore, photovoltaic power generation has obvious intermittent and fluctuations. [0003] Therefore, how to accurately forecast solar radiation has become an urgent technical problem in this field. Contents of the invention [0004] The object of the present invention is to provide a method for short-impe...
