Large-scale offshore wind power cluster fan arrangement optimization method and system

Abstract

The invention discloses a large-scale offshore wind power cluster fan arrangement optimization method and system. The method comprises the following steps: S1, dividing a large-scale wind power cluster area into a plurality of same small-scale wind power plant areas; S2, determining a medium-sized wind power plant of which the scale is smaller than that of the large-sized wind power cluster from the large-sized wind power cluster as an optimization object, wherein the shape of the optimization object is the same as that of the large-sized wind power cluster; S3, determining fan arrangement of the small wind power plant area with the minimum wake flow loss from the fan arrangement candidate points by using a random search algorithm; and S4, calculating the wake flow loss of the large-scale wind power cluster area, and when the wake flow loss of the large-scale wind power cluster area does not conform to the expectation, expanding the scale of the optimization object, and skipping to the step S3 until the wake flow loss of the large-scale wind power cluster area conforms to the expectation. The small-scale wind power plant is used for replacing the whole wind power cluster to serve as an optimization object, the optimization time and cost can be greatly shortened, and the calculation speed and wake flow loss are well balanced.

Description

technical field [0001] The invention belongs to the technical field of design of offshore wind farms, and more specifically relates to a method and system for optimizing the arrangement of wind turbines in a large offshore wind power cluster. Background technique [0002] Since the proposal of the dual carbon goals of peaking carbon emissions by 2030 and neutralizing carbon emissions by 2060, power grids at all levels have responded positively, setting off an upsurge of new energy grid integration. The eastern waters of China are rich in wind resources and have great potential for development, and the construction scale of wind farms can reach 10 million kilowatts. Large-scale offshore wind farm clusters will accommodate thousands of wind turbines. The wake effect is complex and the arrangement is difficult. It is a scale that has never been encountered in China's offshore wind farm construction and international academic research. The number of wind turbines in a 10-millio...
