Objective In the context of the new era, China is undergoing a critical phase of energy structure transformation, particularly amid restrictions on fossil fuel consumption and the transition to a "dual control" system. Renewable energy has become a key pillar of this transformation. However, the existing green power tracing system faces numerous challenges, including complex market transactions, diverse user demands, and significant supply-demand discrepancies.

Method To address the issues in the current green power tracing system, this paper deeply analyzed the demands and challenges faced by the existing green power tracing system and market mechanisms. It focused on enhancing the accuracy of the coefficient acquisition in the average tracing method. To achieve this, the social average power source structure was introduced as a more scientific and reasonable average tracing solution to ensure an effective correspondence between the source and usage of green electricity. Specifically, by systematically analyzing the proportions of various types of power generation sources in a specific region, more accurate data on power sources could be provided. Additionally, this paper proposed an improved certificate-electricity separation tracing method aimed at effectively improving the transparency of the green electricity market and the standardization of data tracking. This method would help ensure market participants' understanding and trust in green electricity, further promoting market development.

Results The introduction of the social average power source structure and the improved certificate-electricity separation tracing method shows that these improvements significantly enhance the transparency of the green electricity market, increase the accuracy of data tracking, and ensure market participants' understanding and trust in green electricity.

Conclusion The improved green electricity tracing system can effectively promote the high-quality development of the renewable energy industry, provide strong support for achieving the "dual control" goals, and thus enhance market fairness and user trust.
