A Multi-Dimensional and Multi-Level Based Collaborative Evaluation of Carbon Reduction in the Power Sector

Achieving deep carbon reduction in the power sector is central to China's green energy transition. This study develops a novel multidimensional and multi-level collaborative evaluation framework designed specifically to assess carbon reduction pathways in electricity systems. Methodologically, we begin by forecasting power demand and the evolution of the generation structure—including thermal, wind, hydro, and photovoltaic sources—based on multi-source power big data, which provides a high-resol
