A method and device for determining a wind power simulation discarding wind sequence

Abstract

The invention provides a method and device for determining a wind power simulation abandonment wind sequence, which firstly obtains operation data of a power system, and then inputs the operation datainto a new energy sequence production model constructed in advance to obtain a wind power simulation abandonment wind sequence, wherein the new energy sequential production model is constructed according to the actual wind power discarding wind sequence. The invention provides an evaluation index of the characteristics of the wind power abandoned wind sequence including the distribution of the abandoned wind period, the abandoned wind duration time and the abandoned wind persistence power quantity, which provides a way for the determination of the wind power simulated abandoned wind sequence.The invention finally realizes the determination of the wind power simulation wind abandonment sequence, analyzes the wind power abandonment characteristics of the high proportion wind power in the future planning level years, further analyzes the reason of the wind abandonment power limitation and provides a basis for solving the problem of the wind abandonment power limitation.

Description

technical field [0001] The invention relates to the field of new energy technologies, in particular to a method and device for determining a wind power simulation abandonment sequence. Background technique [0002] As wind power penetration technology becomes more and more mature, the country pays more and more attention to the development of wind resources, and large-scale wind farms have gradually been connected to the grid; so far, wind power has become the trend of new energy power generation technology; however, due to the large-scale wind power Rapid and disorderly commissioning, lagging power grid construction, insufficient peak shaving capacity of the power grid, instability of wind power output, and limitations of rapidly adjustable power supply capacity in the power grid have resulted in the limited ability of the power grid to accept wind power, resulting in increasing wind curtailment. more serious. [0003] Due to the instability and randomness of wind power, i...

Problems solved by technology

[0006] In order to overcome the lack of further analysis of the reasons for curtailment of wind power and solve the problem of curtailment of wind power due to the lack of evaluation of the characteristics of wind power curtailment in the prior art, the present invention provides a method and device for determining the sequence of wind power simulation curtailment , first obtain the operating data of the power system, and then input the operating data into the pre-built new energy time-series production model to obtain the wind power simulation curtailment sequence; the new energy time-series production model uses the wind power curtailment characteristics obtained from the actual wind power curtailment sequence. The invention provides a method for determining the sequence of wind power simulation curtailment, which provides a basis for further analysis of the causes of curtailment of wind and power reduction and solving the problem of curtailment of wind power
