Embodiment Construction

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings, accompanying tables and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] In the embodiment of the present invention, the large-scale cross-regional wind power installed capacity coordinated planning method takes the wind power combination capacity factor as income and the wind power combination standard deviation as risk, and optimizes the proportion of wind power installed capacity in each region so that in a certain In the case of combined capacity factor, the standard deviation of wind power combination reaches the minimum, which effectively reduces the fluctuation of total wind power output and reduces the total peaking capacity deman...

Abstract

The invention discloses a cross-region wind power installed capacity coordinated planning method which includes the steps of obtaining related data, constructing a calculation model, calculating a wind power combination effective frontier curve, determining a planning result and the like. According to the cross-region wind power installed capacity coordinated planning method, the wind power installed capacity of different regions is planned in a united mode based on an investment combination theory, wind power total contribution fluctuation is effectively reduced, and total peak pitching capacity demands of a system are reduced. The wind power installed capacity of the various regions under the condition that wind power combination quality factors are maximum serves as final optimized results, and the credibility of the wind power capacity and wind power fluctuation are considered to the maximum degree. The top limitation and the bottom limitation of the wind power installed capacity of the various regions are set, conditions, such as electric power network structures, load levels and government policies, of the various regions are sufficiently considered, and the planning result is close to the reality.

Description

technical field [0001] The invention belongs to the technical field of grid planning, and in particular relates to a coordinated planning method for cross-regional wind power installed capacity. Background technique [0002] With the continuous increase of national energy conservation and emission reduction efforts, wind power and other renewable energy power generation has developed rapidly. my country is building eight 10 million-kilowatt wind power bases in Jiuquan, Hami, Mengdong, Mengxi, Hebei, Jilin, Jiangsu, and Shandong. In addition, relevant departments are formulating plans for 10-million-kilowatt wind power bases in Heilongjiang and Shanxi, and the number of 10-million-kilowatt wind power bases in my country will increase from the current 8 to 10. The current wind power planning methods generally carry out wind power planning in local areas according to the local wind power resources, lack of a unified planning guidance method, and do not carry out cross-regional...
