Title:
PHOTOVOLTAIC POWER GENERATION SHORT-TERM POWER PREDICTION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/216576
Kind Code:
A1
Abstract:
The present invention provides a photovoltaic power generation short-term power prediction method and system. The method comprises: calculating a Euclidean distance between meteorological elements on the basis of absolute errors between the meteorological elements at forecasting moments within a forecasting period and corresponding historical moments, a pre-calculated meteorological element standard deviation, and a pre-calculated meteorological element weight value; for the forecasting moments, selecting a preset number of historical moments having a minimum Euclidean distance, obtaining photovoltaic power generation actual power values corresponding to the historical moments, and calculating weight values corresponding to the photovoltaic power generation actual power values; performing weighted summation on the photovoltaic power generation actual power values and the weight values corresponding to the photovoltaic power generation actual power values to obtain photovoltaic power generation predicted power values of the forecasting moments; and summarizing the photovoltaic power generation predicted power values of the forecasting moments to generate a photovoltaic power generation short-term power prediction. The present invention is less dependent on actually measured meteorological data, and is high in adaptability, simple and applicable, reliable in calculation, and easy to implement and deploy on an engineering site.
