Method and system for determining new energy consumption model based on LASSO regression

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...

Problems solved by technology

[0004] At present, the methods for determining the new energy consumption capacity mainly include determining the new energy consumption model, using the power grid planning model, and the time-series production simulation method. These methods mostly rely on mathematical methods, and it is difficult to obtain a clear and clear optimal solution for the final optimization result. , even if the optimal solution is obtained, it is difficult to obtain the optimal interval
