Abstract

The invention provides a static optimization method of power gathering and output electric capacity of a wind power station group, aiming at the problem that the power output electric capacity is not enough and wind power cannot be used for generating electricity by networking of most wind power stations in China. The integral fluctuation characteristic of the output power of a wind power station group is presented by a cumulative annual power output curve of the wind power station, an optimized power transmission capacity objective function optimizing the overall benefit of a power transmission project is established by comprehensively considering factors of power transmission benefit, power transmission construction cost, wind abandoning loss caused by blockage, and the like, and an optimal wind power gathering and output power transmission capability is determined according to the function. The invention provides an effective static evaluation method for the selection of the power output and power transmission capability of kW level wind power bases and can ensure that the comprehensive income of a wind power output and power transmission project reaches the maximization.

Description

technical field

[0001] The invention relates to a method for statically optimizing the power transmission capacity of wind farm group power convergence and external transmission. Background technique

[0002] Global warming is a huge challenge facing human society. It has become an important political and economic issue that has attracted wide attention from all countries, and has become a hot spot in the game of future interests among countries. Carbon emissions from fossil fuel-based electricity production are an important contributor to global warming. The development of renewable energy is an effective way to improve the energy structure. Wind energy is currently the non-hydroelectric renewable energy with the greatest potential for large-scale development and utilization. The grid-connected operation of wind power generation is an important way to develop wind energy resources on a large scale.

[0003] my country is rich in wind energy resources, which are mainly di...
