Business Model Selection Model of Distributed Photovoltaic Energy Storage System in China

There have been researches on the evaluation of the business model of distributed photovoltaic energy storage system (DPESS). The main achievement is to select evaluation indexes from the economic point of view. First, considering the dominant and hidden benefits of DPESS, a complete evaluation index system for business model of DPESS is established from economic benefit, environmental benefit and social benefit. Then, the integrated weighting model which considers the advantages of subjective and objective weighting method is constructed, and the gray cluster trigonometric function evaluation model of DPESS is proposed. The case study shows that the proposed comprehensive evaluation model can rank the comprehensive benefits of the business model of DPESS. Finally, based on the comprehensive evaluation results, a complete DPESS business model site selection evaluation index system from multiple perspectives is constructed, which can provide the basis of selecting DPESS business model for decision makers.
