Problems solved by technology

Existing methods have at least one of the following problems: (1) The wind power sequence obtained by reducing the historical sequence data is a historical scene that has occurred, and lacks the predictability of the future scene, that is, the comprehensiveness of the scene is insufficient; (2) Due to the amount of calculation, the existing generation method of wind power sequence scene method is suitable for the case where the original scene set is small, but not directly applicable to the original scene set with large set elements; Correlation between time period powers

Abstract

The invention discloses a generation method of a wind power sequence scene set, which comprises the following steps of: firstly, constructing a multi-objective optimization model for generating a required wind power sequence scene set; establishing a first objective function considering the sum of distances of all wind power sequence scenes in a wind power sequence scene set, establishing a secondobjective function considering the deviation between the second correlation coefficient of each time period of the wind power sequence scene set and the first correlation coefficient of each time period of the original wind power sequence scene, and obtaining an optimal group of N wind power sequence scenes through a solving model; and therefore, the generated wind power sequence scene set can consider the comprehensiveness of the scene and also consider the correlation between the power of each time period in the wind power sequence scene so as to ensure that the generated wind power sequence scene is more accurate.

Description

technical field [0001] The invention relates to the technical field of power system operation and planning, in particular to a method for generating a wind power sequence scene set. Background technique [0002] With the increasing scale of wind farms connected to the system, the random characteristics of wind farm output cannot be ignored in system analysis. Generating less wind power sequence scenarios that can accurately reflect the characteristics of the original scenario and have predictability for the future has important reference significance for the operation and planning of large-scale wind power systems. At present, the generation method of wind power scene in a single period has certain development, which can be used in engineering practice; but the generation of wind power scene in multiple periods, that is, the generation of wind power sequence scene is still in its infancy. The generation methods of wind power sequence scene sets mainly include Monte Carlo me...
