Using Improved SPA and ICS-LSSVM for Sustainability Assessment of PV Industry along the Belt and Road

Abstract

Scientific and timely sustainability evaluation of the photovoltaic industry along the Belt and Road is of great significance. In this paper, a novel hybrid evaluation model is proposed for accurate and real-time assessment that integrates modified set pair analysis with least squares support vector machine that combines improved cuckoo search algorithm. First, the indicator system is set from five principles, namely economy, politics, society, ecological environment and resources. Then, the traditional approach is established through modifying set pair analysis on the basis of variable fuzzy set coupling evaluation theory. A modern intelligent assessment model is designed that integrates improved cuckoo search algorithm and least squares support vector machine where the concept of random weight is introduced in improved cuckoo search algorithm. In the case analysis, the relative errors calculated by the proposed model all fluctuate in the range of [−3%, 3%], indicating that it has the strongest fitting and learning ability. The empirical analysis verifies the scientificity and precision of the method and points out influencing factors. It provides a new idea for rapid and effective assessment of PV industry along the Belt and Road, as well as assistance for the sustainable development of this industry. This paper innovatively proposes the sustainability evaluation index system and evaluation model for the photovoltaic industry in countries along the Belt and Road, thus contributing to the promotion of sustainable development of the photovoltaic industry in countries along the Belt and Road.

Smart Grid Project Benefit Evaluation Based on a Hybrid Intelligent Model

“…As for the evaluation method, the existing research provides an important reference for the implementation effect evaluation of smart grid projects in this paper. The evaluation methods mainly include traditional evaluation methods and modern intelligent evaluation methods [8]. The traditional evaluation methods include subjective evaluation methods and objective evaluation methods.…”

Smart Evaluation of Sustainability of Photovoltaic Projects in the Context of Carbon Neutrality Target

“…The development situation has been more or less problematic, and the sustainability of PV project development has faced many tests [2]. In particular, in the development of PV projects in the context of carbon neutrality goals from the emphasis on project scale to the direction of improving project quality, it is necessary to implement the concept of sustainable development [3]. To further promote the sustainable development of PV projects and better play a positive role for PV projects to the carbon neutrality target, it is necessary to conduct a scientific evaluation of their sustainability, to provide references and suggestions for PV projects to identify the problems in their sustainable development and improve their sustainability.…”
