A short-term wind speed prediction method and system

Abstract

The invention discloses a short-term wind speed prediction method and system. The method comprises the steps of obtaining historical wind speed data; Wherein the historical wind speed data comprises first historical wind speed data and second historical wind speed data, and the first historical wind speed data is data before the second historical wind speed data; Optimizing the neural network model through a genetic algorithm; Training the optimized neural network model through the historical wind speed data to obtain a prediction model; Performing variational mode decomposition on the secondhistorical wind speed data to obtain a plurality of second nonlinear fluctuation wind speed characteristic data; And predicting the second nonlinear fluctuation wind speed characteristic data throughthe prediction model to obtain wind speed prediction data. The method or the system can effectively improve the reliability of the wind speed prediction precision.

Description

technical field [0001] The invention relates to the field of wind speed prediction, in particular to a short-term wind speed prediction method and system. Background technique [0002] Since the 21st century, energy and environmental issues have become increasingly globalized. The scarcity of fossil energy and the irreversibility of environmental pollution have urged countries around the world to formulate sustainable energy development strategies and build a diversified energy system. Promoting the development of green and renewable energy is a key to solving current energy problems, and it is the only way to promote global energy transformation. [0003] As a new energy power generation technology with zero emission and low operating cost, wind power has been developed and utilized on a large scale worldwide. According to the data released by the Global Wind Energy Council, the cumulative installed capacity of the global wind power market exceeded 500GW in 2017, and the n...

Problems solved by technology

However, with the continuous increase of installed capacity, the problem of grid consumption has become increasingly prominent

The low consumption level of the power grid and severe wind curtailment not only brought immeasurable economic losses to various wind power companies, but also greatly weakened the utilization rate of new energy power generation and restricted the development of new energy industries
