Low-carbon economic benefits evaluation for power generation projects with improved TOPSIS method based on combination weighting

摘要

In the context of the low-carbon economy, economic benefits evaluations for power generation projects focus on the financial benefits and emphasize on the benefit from carbon-emission reduce. Thus, this paper firstly built an economic benefits evaluation index system for power generation projects based on low-carbon financial benefits and carbon-emission reduction efficiency. Then, it established an improved TOPSIS evaluation model based on orthogonal projection method and combination weighting which is determined by AHP subjectively and variation coefficient method objectively. Finally, the empirical analysis of wind power projects' constructions verified the feasibility and effectiveness of the evaluation model using that new method
