Abstract

The invention relates to a wind power consumption ability analysis method. The method comprises the following steps: 1) data of a power system are acquired; 2) the start-up mode of the power system is determined, and the minimal start-up capacity of a non-wind turbine generator is determined according to the start-up mode of the power system; 3) the thermal stability limit and the transient stability limit of each main transmission channel and the maximal transmission capacity of each main transmission channel are calculated; 4) the maximal wind power output provided by each hour is calculated; 5) the wind power output based on network constraints is calculated; 6) the wind power accommodation space based on the system peaking capability is calculated and obtained; 7) the actual wind power output and the maximal transmission capacity of each main transmission channel are calculated, and the limited output of each main transmission channel in the power system is calculated respectively and correspondingly; 8) wind power generation is calculated, and the wind power limit is calculated; and 9) an abandoned wind power ratio is calculated. The method of the invention can intuitively and accurately represent the wind power consumption ability by the power system.

Description

technical field [0001] The invention relates to the technical field of wind power grid connection, in particular to a method for analyzing wind power accommodation capacity. Background technique [0002] Wind power is a renewable green energy. In recent years, with the adjustment of my country's energy structure, green energy has been paid more and more attention. In order to ensure energy security and promote environmental protection, my country has introduced a series of new energy development policies to encourage large-scale development and utilization of wind power. In 2010, my country's wind power installed capacity surpassed that of the United States and became the country with the largest wind power installed capacity in the world. By the end of 2014, my country's wind power installed capacity had reached 95.81 million kilowatts. It is expected to reach 200 million kilowatts. However, the development of wind power in China is extremely unbalanced. Due to the limitat...
