With the increasing global concern over climate change and sustainable development, renewable energy sources such as wind power, solar energy, and hydroelectric power are becoming key pathways for transforming electricity systems. Scholars both domestically and internationally are exploring innovative and optimized market mechanisms to enable effective participation of renewable energy in the electricity market, aiming to maximize its benefits. However, the current evaluation system for green power projects is still inadequate, primarily focusing on economic benefits and lacking comprehensive methods for project assessment. To address this, a comprehensive benefit evaluation system has proposed. An analysis model for the economic, environmental, and social benefits of new energy stations has been developed, delving into the composition of economic benefit indicators and emphasizing the importance of social and environmental benefits in project decision-making. A comprehensive evaluation index system and fuzzy analysis method have established to provide quantitative assessment tools for green power trading projects at new energy stations. Based on practical examples, this provides objective evidence for related decision-making. The results indicate that this method outperforms others on most evaluation indicators, validating its effectiveness in project assessment. The study accurately concluded that green power projects have strong comprehensive benefits and provided specific recommendations to promote the healthy development of the green power trading market, which is crucial for advancing the widespread application of renewable energy and global green development.
