Marine booster station site selection optimization method

Abstract

The invention relates to a marine booster station site selection optimization method. The method comprises the following steps that an offshore closest point a of a marine booster station is obtained according to a coordinate of a land centralized control center; a gravity center point b of a marine wind power plant is obtained according to all coordinates of N draught fans, and a straight line L is obtained according to the gravity center point b and the offshore closest point a; multiple points c are preset on the straight line L, coordinates of the points c, a coordinate of the gravity center point b and a coordinate of the offshore closest point a are preset to be initial coordinates of the marine booster station respectively, and corresponding collecting power line layouts of the marine wind power plant are obtained respectively; when the total cost corresponding to one point c or the gravity center point b or the offshore closest point a is smaller than or equal to the preset total cost, the point is the optimal coordinate of the marine booster station. According to the marine booster station site selection optimization method, marine wind power construction conditions can be comprehensively considered, and the construction cost of the marine wind power plant is reduced to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of offshore wind power, in particular to a site selection optimization method for an offshore booster station. Background technique [0002] Today, wind power has become the fastest growing renewable clean energy in the world, especially offshore wind power has the advantages of high wind speed, stable wind force, less wind shelter and interference, and large power generation. It is an inevitable trend for wind power development to shift from land to sea in the future. my country is rich in offshore wind energy resources, and the wind energy reserves that can be developed at a height of 10m offshore are about 750 million kW. Offshore wind power will definitely become the focus of my country's future clean energy development. [0003] For an offshore wind farm with a fixed capacity, when the coordinates of the wind turbines are determined, the coordinates of the offshore booster station directly affect the la...

Problems solved by technology

[0007] However, there are deficiencies in the existing site selection methods for offshore booster stations: the mean value clustering method does not consider the total cost of different coordinates of the offshore wind farm and the difference in the price of high-voltage submarine cables, and the considerations are too simplified; the DDR method only considers the geometric center of the wind farm and The wind farm is close to two points on the side of the grid connection point, and other possible coordinates of the offshore wind farm have not been discussed, and the selection range is relatively limited

The existing two methods cannot obtain the maximum advantage of cable investment cost in actual engineering.
