To effectively facilitate the low-carbon transition of energy and power systems

it is imperative to not only design transition paths at the macro level

but also conduct system feasibility analysis at the operation level. This study proposes a comprehensive analytical methodology for evaluating the low-carbon transition pathways of the power system. Based on the model built and paths designed in Part I of the paper

Part II extends the analysis by conducting a production simulation of the power system under various predefined scenarios

thereby validating the electric power and energy balance. The flexibility and resilience of the power system operation are evaluated under both normal and extreme weather conditions. Furthermore

the economic viability of different transition paths is compared

and the impacts of multiple factors on the annualized cost of each path are examined through sensitivity analysis. Together with Part I

this paper achieves the soft-linking of bottom-up power system operation simulation and economic analysis to top-down development scenario design

providing support for the rationality and feasibility verification of macro transition paths of China's power system towards carbon neutrality by 2060.
