Wind power plant and photovoltaic power station group output non-mechanism model modeling method considering correlation

The invention provides a wind power plant and photovoltaic power station group output non-mechanism model modeling method considering correlation. A delay link is adopted to represent delay correlation between adjacent wind power plants or between adjacent quarters of a photovoltaic power station, an ant colony optimization algorithm is adopted to solve the delay time, finally, the output of the adjacent wind power plants or the output of the adjacent quarters of the photovoltaic power station is predicted based on the delay time, and in the prediction process, a transfer function selects first-order Taylor series expansion. The method can predict the output of other wind power plants according to the output of a certain wind power plant or predict the output of the next season according to the output of a certain photovoltaic power station for the delay correlation between the outputs of the adjacent wind power plants and between the outputs of the adjacent seasons of the photovoltaicpower station, and provi
