基于物源可拓模型的光伏发电经济效益评价模型

Economic Benefit Evaluation Model of Photovoltaic Power Generation Based on Provenance Extension Model

由于传统模型在光伏发电经济效益评价应用中响应时间比较长,评价效果不佳,本文提出了基于物源可拓模型的光伏发电经济效益评价模型。根据光伏发电经济收益的影响特征,从工程概况、投资、成本以及收益4个方面选择评价指标,构建评价指标体系,利用判断矩阵确定评价指标熵权,并利用物源可拓模型定量评价对象,确定经济效益指数。同时,根据评价准则确定等级,实现对光伏发电经济效益的定性评价,完成基于物源可拓模型的光伏发电经济效益评价模型构建。实验证明,构建模型响应时间不超过1s,在光伏发电经济效益评价方面具有良好的应用前景。

Due to the long response time and poor evaluation effect of traditional model in the application of photovoltaic power generation economic benefit evaluation,this paper proposes a photovoltaic power generation economic benefit evaluation model based on source extension model.According to the influence characteristics of the economic income of photovoltaic power generation,the evaluation index is selected from the four aspects of project overview,investment,cost and income,and the evaluation index system is constructed.The entropy weight of the evaluation index is determined by the judgment matrix,and the evaluation object is quantitatively evaluated by the source extension model,the economic benefit index is determined.At the same time,according to the evaluation criteria to determine the grade,to realize the qualitative evaluation of the economic benefits of photovoltaic power generation,and complete the construction of the economic benefits evaluation model of photovoltaic power generation based on the source extension model.The experimental results show that the response time of the model is shorter than 1 s,which has a good application prospect in the economic benefit evaluation of photovoltaic power generation.
