Offshore wind plant output typical scene generation method and storage medium

Abstract

The invention discloses an offshore wind plant output typical scene generation method and a storage medium, and the method comprises the steps: collecting offshore wind plant output data and offshore meteorological data for detection and processing, and obtaining new offshore wind plant output data and offshore meteorological data; dividing the new offshore wind plant output data and offshore meteorological data into S seasons according to the ocean monsoon features, obtaining k weather feature indexes of the output of the offshore wind plant in the s-th season, wherein the weather features include ocean non-extreme weather and ocean extreme weather; according to the characteristic index of the ocean non-extreme weather, determining an offshore wind plant output typical scene and a probability thereof under the ocean non-extreme weather in the s-th season; and according to the characteristic index of the extreme day, determining an offshore wind plant output typical scene and a probability thereof in the s-th season ocean extreme weather. According to the method, the weather characteristic indexes influencing the output of the offshore wind plant are accurately identified through correlation analysis, and the accuracy and typicality of the selected scene are improved.

Description

technical field [0001] The present invention relates to the technical field of offshore wind power generation, in particular to a method for generating a typical scene of output of an offshore wind farm and a storage medium. Background technique [0002] my country has a long coastline and abundant offshore wind energy resources, which have great potential for development. Compared with land wind resources, offshore wind energy resources have many advantages. Many indicators, such as average wind speed, effective wind energy density, wind power level, available hours of effective wind speed, and turbulence intensity, are superior to land wind resources. But at the same time, affected by geographical location, coastal wind energy resources have obvious characteristics of marine monsoon. For example, the wind in winter and summer may show a certain wind direction, and coastal meteorological disasters occur frequently. Wind power has both pros and cons. Affected by the endowm...

Problems solved by technology

[0004] However, the current wind farm output modeling method is mainly based on the characteristics of land wind farms, and is established according to the mapping relationship between land wind speed and wind turbine output. Larger differences, stronger anti-peaking characteristics, and variable marine climate characteristics make offshore wind power have more complex and extreme output scenarios, and these
