Abstract

Clean and low-carbon development is the core goal of the new-type power system. To facilitate a comprehensive evaluation of the carbonintensity, a source-grid-load-storage evaluation system of new-type power system under carbon peaking and carbon-neutral goal is established. A comprehensive new type of low-carbon indicator system for power system source-grid-load-storage is constructed to address the issues of redundant indicators, strong inter-correlation, limited practical utility, and the absence of energy storage in existing source-grid-load evaluation system. In response to the limitations of subjective and objective weighting methods, the AHP-CRITIC hybrid weighting method is introduced, and the comprehensive weights are calculated based on the least squares method. In light of China’s dual carbon goals and addressing the subjective biasof traditional fuzzy evaluation, an improved FCM fuzzy comprehensive evaluation method based on data-driven prediction is proposed. This method enhances the objectivity and scientific rigor of the evaluation model, while ensuring its applicability over extended time spans, thereby achieving a comprehensive evaluation of the low-carbon performanceof the power system. Finally, the effectiveness of the evaluation model is validated using the power system of a city in western China as a case study.
