Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0040] like figure 1 As shown, a wind farm micro site selection method specifically includes the following steps:

[0041] S01. Based on the actual project construction needs, determine the wind farm area and the start and end time of each phase of the wind farm, and then calculate the investment cost of each phase of the wind farm. like image 3 Shown is a schematic diagram of the timeline of a multi-phase wind farm project.

[0042] The start and end time of each period of the wind farm directly affects the number of wind turbines in the wind farm and the annual power generation,...

Abstract

The invention relates to a multiphase wind power plant micro site selection method. Fine adjustment is performed on an optimal blower position in a movable grid neighborhood through regional gridding based on a genetic algorithm with extremely high global search capacity by adding tabu search in the genetic algorithm so that the algorithm is enabled to have great stability and capacity of overcoming premature in the optimization process, a defect of insufficiency of local search capacity of the genetic algorithm is compensated, whole algorithm performance is enhanced, and optimized distribution of irregular shapes of wind power plants can be effectively processed. Compared with conventional fractional optimization of multiphase wind power plants, wake flow influence between wind power plants of different phases is considered in the optimization process so that power generation efficiency of a wind turbine can be enhanced, and long term of optimal benefit of the wind power plants can be pursued. The method can be extended to the solution of similar problems, and research results are beneficial for enhancement of wind energy utilization efficiency and economic benefit of the wind power plants so that the method has high practicality.

Description

technical field [0001] The invention relates to a method for microscopic location selection of wind farms, in particular to a method for microscopic location selection of multi-phase wind farms. Background technique [0002] As a new type of clean and renewable energy, wind energy has very broad application and development prospects. Wind power converts wind energy into electrical energy through wind turbines. The main purpose is to save traditional fossil energy to meet the growing energy demand and reduce environmental pollution. [0003] At present, the low utilization rate of wind energy is still the key factor restricting the development of the wind power market, and how to further improve the efficiency of wind power is also the focus of domestic and foreign scholars' research. Reasonable planning of fan arrangement in wind farms is one of the important means to improve the utilization rate of wind energy. The research on wind farm planning and design mainly focuses o...
