Description

technical field

[0001] The invention relates to the technical field of new energy power generation, in particular to a method and system for optimizing and predicting the structure of new energy power sources in a region. Background technique

[0002] New energy power generation has been favored by countries all over the world because of its environmental friendliness, low pollution and renewable characteristics. Encouraged and supported by national policies, my country's new energy power generation has developed rapidly in the past ten years, and has now become the country with the largest wind power scale and the fastest development speed in the world. The sudden emergence of new energy provides an alternative solution for the sustainable utilization of energy in our country, but the power generation output of new energy is unstable and fluctuates randomly, large-scale, centralized new energy development mode, large-capacity, long-distance, high-voltage power transmission ...

Embodiment Construction

[0056] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and together with the embodiments of the present invention are used to explain the principle of the present invention and are not intended to limit the scope of the present invention.

[0057] A specific embodiment of the present invention discloses a method for optimizing and predicting the structure of new energy power sources in a region. By constructing a three-stage comprehensive optimization forecast model of "total amount-structure-component", the structural optimization of new energy sources is predicted. Such as figure 1 As shown, the total development of new energy power sources is predicted and analyzed. On the premise of not destroying the trend and causality in the original data, the improved gray prediction model is used to infer the changes of the series itself...
