Embodiment Construction

[0059] The following will be combined with the accompanying drawings in the embodiments of the present invention, the technical solution in the embodiments of the present invention will be described clearly and completely, it is clear that the embodiments described are only a part of the embodiment of the present invention, not all embodiments. Based on embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative work, are within the scope of protection of the present invention.

[0060] At present, there are three common methods for determining the capacity of new energy consumption:

[0061] 1. Low-dimensional function mapping method

[0062] Two-dimensional model to high-dimensional model mapping is a common method of building three-dimensional models, through the support vector machine under the kernel function to map the two-dimensional model to three-dimensional space, support vector machine is to solve th...

Abstract

The invention relates to a method and system for determining a new energy consumption model based on LASSO regression. The method comprises the following steps: constructing a new energy consumption model; performing dimension reduction calculation on the new energy consumption model by using LASSO regression, and judging whether a mathematical relationship exists among factors: if yes, representing a multi-dimensional model through a factor function relational expression; and if not, representing the multi-dimensional model by using a Peaks function. The multi-dimensional new energy response surface model based on LASSO regression can vividly describe the condition that the new energy utilization rate changes along with factors, and has important significance for researching the influence of multiple uncertain factors on the new energy utilization rate.

Description

Technical field [0001] The present invention relates to the field of new energy evaluation technology, in particular to a method and system for determining a new energy consumption model based on LASSO regression. Background [0002] Energy is the foundation of sustainable economic and social development and an indispensable driving force for human production and life. With the increasing prominence of problems such as energy security, ecological environment and climate change, accelerating the development of new energy has become the general consensus and concerted action of the international community to promote energy transformation and development and cope with global climate change. [0003] China actively promotes the development of new energy, by the end of 2015, China's cumulative installed capacity of new energy reached 171.48GW, ranking the forefront of the world. Due to the randomness and volatility of new energy output such as wind and light, and because of the endowm...
