Abstract

The present belongs to the new energy power generation technical field and relates to a probability distribution-based wind farm cluster output power smoothing effect analysis method. The method includes the following steps that: the wind power data of a wind farm are acquired and are adopted as wind electricity output power sample data; normalization processing is performed on the sample data, so that processing-post new data can be obtained; wind farm cluster output power smoothing effect indexes are obtained through calculation according to the new data; and the result of a wind farm cluster output power smoothing effect is determined according to the probability distribution of the indexes. According to the probability distribution-based wind farm cluster output power smoothing effect analysis method of the present, the three smoothing effect indexes, namely, wind electricity output power weighted probability, maximum output power simultaneity rate and average absolute fluctuation coefficient, are provided from the perspective of probability distribution; and influence on the wind farm cluster output power smoothing effect caused by different space scales can be obtained through comparison and analysis.

Description

technical field [0001] This application relates to the technical field of new energy power generation, in particular to a method for analyzing the smoothing effect of wind farm cluster output based on probability distribution. Background technique [0002] In recent years, with the increasing energy demand, the greenhouse effect and various environmental pollution problems have become increasingly serious, vigorously developing new energy has become an important part of the sustainable development strategy of various countries. Among them, wind power has become the leading new energy development with its relatively mature technology, abundant resource reserves and low power generation cost. However, with the gradual increase of the penetration rate of wind power in the power grid, the characteristics of wind power generation such as volatility, randomness and uncertainty have brought a lot of problems to the safe and stable operation of the power system, power quality and it...
