Abstract

The wind-solar hybrid power generation project combined with electric vehicle charging stations can effectively reduce the impact on the power system caused by the random charging of electric cars, contribute to the in-situ wind-solar complementary system and reduce the harm arising from its output volatility. In this paper, the site selection index system of a landscape complementary power generation project is established by using the statistical methods and statistical analysis in the literature. Subsequently, using the Analytic Network Process to calculate the index weight, a cloud model was used in combination with preference ranking organization method for enrichment evaluations to transform and sort uncertain language information. Finally, using the results of the decision-making for the location of the Shanghai wind-solar complementary project and by carrying out contrast analysis and sensitivity analysis, the superiority and stability of the decision model constructed in this study was demonstrated.

Highlights

  • With the rapid development of economy, the number of traditional car purchases has grown rapidly, leading oil consumption rising, air pollution is becoming more and more serious

  • On the basis of the above analysis, this study aims at expanding the PROMETHEE method to uncertain language environment using a cloud model considering the index correlation and solving the index weight using AHP

  • In order to further verify the accuracy and superiority of the model built in this study, it is necessary to compare the model constructed in this study with the traditional uncertain language environment decision model

Summary

Introduction

With the rapid development of economy, the number of traditional car purchases has grown rapidly, leading oil consumption rising, air pollution is becoming more and more serious. This situation leads that greater demands were being placed on the development of electric car. Solar energy and wind energy have the advantages of universal distribution, cleanliness, immense resource potential and prolonged usage. Renewable energies such as wind and solar are intermittent, coupling solar power with wind power can attain a complementary effect. At night or during cloudy days, the sunlight is weak, but the wind is strong
