Abstract

The invention discloses an active power control method by considering fatigue load distribution and productivity of a wind power plant. Wind power plant fan fatigue distribution and total active powerare taken as a mixed target function to optimize the active power control strategy of the wind power plant, and the influence of the wind power plant capacity and fatigue distribution on the wind power cost is comprehensively considered, so that the wind power plant maintenance frequency and shutdown time cannot be increased due to unbalanced fatigue distribution, and a more reasonable active power control method is obtained.

Description

technical field [0001] The invention belongs to the technical field of wind farms, and more specifically relates to an active power control method considering the fatigue load distribution and production capacity of wind farms. Background technique [0002] Energy is an important material basis for the survival and development of human society, and is related to national economy and people's livelihood and national strategic competitiveness. At present, the world's energy structure is undergoing profound adjustments, the overall relationship between supply and demand is easing, the response to climate change has entered a new stage, and a new round of energy revolution is booming. As countries around the world pay more and more attention to issues such as energy security, ecological environment, and climate change, the development of new energy will definitely be the top priority in this round of energy revolution. In my country's geographical environment, there are long co...
